SSPI Innovators And Honorees...A Gathering It's A Good Thing

Recognizing outstanding new contributions to the field of satellite communications by both private-sector and public-sector organizations, awards
The Society of Satellite Professionals International (SSPI) announced today the recipients of its 2012 Industry Innovators Awards. The Industry Innovators Awards, introduced in 1993, recognize outstanding new contributions to the field of satellite communications by both private-sector and public-sector organizations. Honorees are chosen by a committee of industry experts for accomplishments ranging across a broad spectrum of advanced satellite technology and business applications.

The 2012 Industry Innovators Awards will be presented during the Stellar Reception, sponsored by Arianespace, Intelsat and Space Systems/Loral, immediately prior to SSPI’s annual Gala on the opening night of the SATELLITE conference. The Stellar Reception will take place at the Renaissance Washington. SSPI will also honor the recipient of the Stellar Award for Government Service, Air Force Lt. Gen. Ellen M. Pawlikowski, announced in January.

Innovation in Ka-Band Services

SSPI honors two for-profit companies and strategic partners for the development and launch of transformative high-throughput satellites that seek to provide broadband Internet access to homes and small offices at rates and speeds comparable to terrestrial alternatives.

Launched in December 2010, Eutelsat’s KA-SAT satellite ushered in a new era of competitively priced satellite Internet services in Europe and the Mediterranean Basin. The satellite delivers throughput of over 70 Gbps with high frequency reuse achieved via 82 spotbeams. KA-SAT powers the Tooway broadband service, the first to implement ViaSat’s high-capacity technology, to provide speeds of up to 10 Mbps download and 4 Mbps upload, making it the fastest satellite broadband service within its footprint and comparable to ADSL. Speeds of up to 50 Mbps download and 20 Mbps upload address professional markets. With 30 million homes in KA-SAT's coverage still unserved or underserved by ADSL, KA-SAT is on the way to making a significant contribution to meeting pent-up broadband demand from consumers and enterprises.

October 2011 saw the launch of ViaSat-1, the world’s highest capacity satellite offering 140 Gbps of total throughput over the USA.  ViaSat-1 represented a visionary initiative by the firm to change the paradigm of broadband services delivered via satellite.  Spotbeams are focused on the 70% of the US population where most subscribers are located, and frequency reuse boosts total capacity by a factor of 18. The high-capacity satellite system also includes next-generation ViaSat ground system technology, which includes the company's advanced acceleration technology.  The Exede broadband services introduced in January 2012 promise to provide a 10x increase in download speeds and 6x increase in upload speeds compared with satellite alternatives.

Innovation in the Mitigation of Galaxy-15

SSPI honors two satellite operators that forged an unprecedented collaboration to prevent a perfect storm of radio frequency interference over the US domestic arc. On April 5, 2010, the Galaxy 15 C-band spacecraft, operated by Intelsat at 133 degrees west, stopped responding to commands. The satellite continued to relay cable TV programming but, without spacecraft telemetry and tracking, it started an uncontrolled drift eastwards through the crowded orbital arc, threatening interference with other satellites, beginning with an SES spacecraft.  Intelsat and SES developed an effective mitigation strategy including innovative spacecraft maneuvers to avoid interference from “ZombieSat”, customer communication strategies and a unique software utility that together averted disaster. SES successfully performed the first "leap-frog" maneuver, to be repeated by the other operators passed by Galaxy 15. Throughout the nearly year-long crisis, not one network programmer lost transmission, and the extraordinary efforts of Intelsat and SES and the other operators in the North American arc won them the respect of customers across America.

Innovation in Industry Collaboration on the Safe Use of Space SSPI honors an association formed by satellite operators to make operations in space safer for themselves and more reliable for their customers. The Space Data Association (SDA), incorporated in the Isle of Man, is the first organization created specifically to share information previously considered confidential by commercial operators. The SDA’s Space Data Center provides a common location for its operator members to securely pool satellite ephemeris data and radio frequency information in order to reduce the risk of collision in space and to more rapidly mitigate the impact of radio frequency interference. It is also the only system in existence today that routinely accounts for the maneuvers of all its member’s satellites making the output of the system far more accurate than any other in use today.  Founded by Intelsat, SES and Inmarsat in 2009 to address the increased crowding of Earth orbit and the lack of reliable, industry-wide data on pending collisions, SDA has grown to 12 member organizations and has over 350 satellites in its database.

Innovation in Identifying the Source of Interference

SSPI honors Comtech EF Data for developing, on its own initiative and at its own expense, a critical component of a long-term solution to the problem of satellite radio frequency interference (RFI). When interference occurs on a satellite, the first and most challenging problem is to identify the source of that interference, because without this information, almost nothing can be done to resolve the problem.  The industry currently uses complex and costly geo-location systems and large amounts of human labor to pinpoint interference sources.

Responding to requests from the industry, Comtech EF Data developed a technology called MetaCarrier that fulfills three important requirements: it is readable regardless of any encryption of the signal; it uses a format that is universally accepted; and it adds minimal overhead to the transmission.  MetaCarrier uses spread-spectrum modulation of a very low data-rate carrier that contains metadata about the carrier and the device that is emitting it.  The energy of this "meta-carrier” is spread across the bandwidth of the carrier being identified, which adds only a miniscule amount of noise to the signal.  Because it is separately encoded from anything else riding on the signal, it can be encoded and decoded regardless of encryption or conditional access, and can be used on any static carrier, SCPC, video or other configuration.  It represents a significant advance over the only other approach to digital carrier ID, which uses the DVB-S2 Network Interface Table and works only with that technology.

As a service to the industry, Comtech EF Data has proposed that MetaCarrier be adopted by DVB as an open standard, to be incorporated into new terminal equipment and downloaded by firmware update to existing equipment where possible.  Once it achieves widespread adoption, carrier ID will permit satellite operators and their customers to identify, in minutes, the equipment from which an interfering signal originates, which will be a major step on the long road to making satellite RFI a thing of the past.  

"Our Awards Committee focused on innovations in areas that deserve the industry's attention," said Keith Buckley, Chairman of SSPI's Board and CEO of ASC Signal Corporation," and on innovations that open doors to vast new opportunities for the industry. SSPI is proud to be able to draw attention to these innovative organizations and salute their achievements on behalf of our industry."

SES Moves AMC-3 Want A Better Reception? Move The Satellite!

One way to optimize satellite coverage is to move it, such as...

SES S.A. (Euronext Paris and Luxembourg Stock Exchange: SESG) today announced that the AMC-3 satellite is being relocated from its former location of 87 degrees West to 67 degrees West to optimize coverage of Mexico, Central America and the Caribbean. The 67 degrees West orbital position offers an extensive Ku-band satellite frequency range and excellent viewing angles for coverage of the Americas and the Caribbean.

The drift was initiated in January and the satellite is scheduled to arrive at its new orbital location on February 24th.

AMC-3 was launched in 1997 into the orbital location of 87 degrees West. Built by Lockheed Martin, the spacecraft carries Ku- as well as C-band transponders. The AMC-3 spacecraft was replaced at the 87 degrees West slot by the SES-2 satellite launched on board an Ariane 5 vehicle on September 22, 2011. AMC-3 has enough fuel to operate in geostationary orbit until 2017. At 67 degrees West, AMC-3 will be co-located with the AMC-4 satellite, which has been providing services over Latin America and the Caribbean since its deployment at this position in 2010. Together, AMC-3 and AMC-4 will be able to offer 28 commercially available Ku-band transponders (36 MHz equivalents) at 67 degrees West.

Romain Bausch, President and CEO of SES stated: “The relocation of the AMC-3 satellite once again demonstrates the operational flexibility provided by a 50 spacecraft strong global fleet. The orbital slot of 67 degrees West offers an additional growth opportunity to SES to efficiently serve Mexico, Central America and the Caribbean with satellite solutions for television distribution, broadband connectivity and government services.”

SES-3 Is A Real Mover And Shaker In Space

Imagine being a satellite and having to move to a new position in space...that takes two months.

SES today announced that the SES-3 satellite is being relocated from its former location over North America to Asia, an area experiencing great demand for state-of-the-art, reliable satellite capacity.

The SES-3 satellite is being relocated to 108.2 degrees East to provide coverage of the Middle East and South Asia regions, where SES experiences growing customer demand. The drift began in mid-December 2011 and the satellite arrived at its new orbital location on February 6, 2012.

SES-3 is a young satellite as it was just launched in July of 2011. Once reaching 108.2 degrees East, the planned coverage is capable of supporting such applications as video, voice, data, and end-to-end communications networks. With MAC-1 compliance and encrypted tracking, telemetry and control, the satellite is also well positioned to meet the secure communications needs of government customers.

The launch on an ILS Proton rocket took place from Baikonur, Kazakhstan. Based on Orbital’s GEOStar-2™ bus, SES-3 is the first of two satellites built by Orbital for SES. SES-3 was co-launched with the KAZSAT-2 satellite.

Romain Bausch, President and CEO of SES, stated: “With a fleet of 50 spacecraft in orbit around the globe, SES has the operational flexibility to swiftly respond to shifting customer demand by re-deploying in-orbit capacity without affecting existing services.

Tip Osterthaler, President and CEO of SES Government Solutions added, “The relocation of the SES-3 satellite is a result of continued engagement and dialogue with our customers and in response to the growing demand for bandwidth to support critical communications capabilities. This move is a confirmation of our commitment to provide affordable and vital capability for our government customers.”

Space Systems/Loral... Thrusting To Its Slot (Satellite)

Space Systems/Loral (SS/L) (NASDAQ: LORL) has announced that the
SES-4 satellite, designed and built for....

....SES (EURONEXT PARIS: SESG) (LUXEM: SESG), is successfully performing post-launch maneuvers. The satellite deployed its solar arrays yesterday following its launch on Tuesday aboard a Proton Breeze M launch vehicle, provided by International Launch Services (ILS), from the Baikonur Space Center in Kazakhstan. The satellite's main thrusters are maneuvering SES-4 into its geosynchronous orbit.

"As the most powerful satellite in the SES fleet, SES-4 will provide new, state-of-the-art satellite capacity across three continents," said Martin Halliwell, Chief Technology Officer of SES. "This is our second SS/L-built satellite to launch in the last six months, and we continue to work closely with SS/L on another important addition to our fleet, which is scheduled to launch later this year."

SES-4 is a C- and Ku-band satellite designed to provide Fixed Satellite Services (FSS) to the Americas, Europe, Africa, and the Middle East. With approximately 20-kW end-of-life power, it is based on the decades-proven SS/L 1300 platform, which has the flexibility to support a broad range of applications and technology advances. When the satellite completes in-orbit testing, it will replace NSS-7 at 338 degrees East longitude. SES-4 is SS/L's seventh 20-kilowatt satellite to be placed into orbit. It has more transponders than any other satellite in the SES fleet with 52 C-band and 72 Ku-band transponders. With this launch, there are 67 SS/L-built 1300 platform satellites currently in orbit.

Ball Aerospace... More MOIRE (Satellite)

Ball Aerospace & Technologies Corp. has successfully completed a Preliminary Design Review (PDR) for the....

....Membrane Optic Imager Real-Time Exploitation (MOIRE) program under contract to the Defense Advanced Research Projects Agency (DARPA). Ball Aerospace is incrementally demonstrating technologies needed to develop a large, lightweight geosynchronous space-based telescope using advanced diffractive optics membrane to provide persistent, real-time, tactical video to the war fighter. The PDR, which concluded on August 30, demonstrated the ability to create a diffracted optical element (DOE) on a membrane. Ball Aerospace showed an 80 centimeter diameter, 32.5 meter focal length imaging DOE. This component is typical of what would be used for a 5 meter diameter telescope. Ultimately, the system is envisioned to use multiple membranes to form a collection aperture that is 20 meters in diameter. MOIRE seeks to validate the manufacturability of large membranes, large structures to hold the optics tight and flat, and also demonstrate the secondary optical elements needed to turn a diffraction based optic (such as photon sieve) into a wide, bandwidth imaging device.

“The use of membrane optics is an unprecedented approach to building large aperture telescopes,” said Ball Aerospace President and CEO, David L. Taylor. “With the technology being developed on the MOIRE program, Ball Aerospace is broadening its role in geosynchronous imaging.” In phase two of the program now underway, a sub-aperture section of a 5 meter diameter demonstration telescope will be designed and built. Five additional risk-reduction options in phase two of the program will be addressed prior to Ball building a flight demonstration.

United Launch Alliance On... The Final Shuttle Flight...

ULA homepage linkOn behalf of the men and women of United Launch Alliance (ULA), we would like to recognize the outstanding contributions to mankind of NASA’s Space Shuttle Program.

For more than 30 years, the Space Shuttle has launched American heroes into space, enabling scientific discovery, increasing our understanding of our planet and its changing climate, and facilitating assembly of the International Space Station – providing humanity’s most extended presence in space.

Throughout the shuttle era, the U.S. space industry has been proud to work together as a team with NASA to build, launch, operate and land the world’s first reusable space transportation system. Through triumphs and setbacks, the people of NASA and the Shuttle workforce have never lost sight of America’s leadership in space and NASA’s role in expanding the frontier. The space shuttle is a remarkable spacecraft with a rich legacy of accomplishments that stands as an icon of America’s can-do spirit.

[color=yellow]Although the space shuttle has completed its final mission, ULA is launching NASA into the future with five historic missions in just six months, delivering critical NASA payloads to orbit in support of the global science community.[/color] This campaign is unprecedented not only for its reach across the solar system, but also for its tempo and precision.
Last month, an ULA Delta II launched Aquarius, improving our understanding of Earth’s climate. In August, an Atlas V will launch Juno on a five-year journey to Jupiter to unlock its inner secrets. In September, a Delta II will send GRAIL to map the Moon’s quirky gravitational field. In October, a Delta II will launch the National Polar-Orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project (NPP) into polar orbit, providing weather continuity and climate data. Finally, in November, an Atlas V will launch Mars Science Laboratory (MSL) with Curiosity, the largest ever Mars rover on a mission to the red planet.

In addition, under the Commercial Crew Program, ULA is proud to be the launch vehicle of choice for Sierra Nevada’s Dream Chaser and Blue Origin’s Space Vehicle, and compete to support Boeing’s CST-100 program. Working together with NASA, these established companies and entrepreneurs plan to usher in a bold new era of human spaceflight; not only transporting NASA astronauts to the International Space Station, but opening spaceflight to non-government passengers for the first time.

We at United Launch Alliance are honored to have been NASA’s partners since the launch of John Glenn 50 years ago on an Atlas,[color=yellow] and are proud to boldly launch NASA into the future.[/color]

NASA JPL... Juniper Adventure Draws Ever Closer

The fairing for this spacecraft is now in place and the launch date nears...

Processing on NASA's Juno spacecraft continues, with the spacecraft being inserted into its payload fairing yesterday, (July 18, 2011). The payload fairing acts as a protective cocoon that will shield Juno from the elements during the first 205 seconds of the spacecraft's ascent to orbit. The encapsulation process is expected to take about four days. On Friday, July 15, the Juno team used a process called gamma-ray radiography to inspect solder connections leading to a heater element aboard one of Juno's two magnetometers. The results of the inspection indicated there was an ample amount of solder connecting wire leads to the heater, enabling it to operate effectively during its mission.

[color=orange]Technicians use an overhead crane to lower NASA's Juno spacecraft onto a fueling stand at Astrotech's Hazardous Processing Facility in Titusville, Fla. Image credit: NASA/KSC[/color]

The Juno spacecraft carries two redundant Flux Gate Magnetometer instruments that will measure Jupiter's powerful magnetic environment. Lab testing of heaters similar to ones on Juno, designed to keep the Flux Gate Magnetometer instruments warm in space, had indicated a small probability that wire connections might not operate as expected. As a precaution, NASA and Juno mission personnel had decided to inspect the Juno heater elements and, if necessary, repair solder joints connecting the heaters' electrical wires to their mounting surfaces to ensure mission success. "This test gave us confidence that our magnetometer will work as advertised in just about the harshest environment you could find in the solar system," said Scott Bolton, Juno's principal investigator from the Southwest Research Institute in San Antonio.

The launch period for Juno opens Aug. 5 and extends through Aug. 26. For an Aug. 5 liftoff, the launch window opens at 8:34 a.m. PDT (11:34 am EDT) and remains open through 9:43 a.m. PDT (12:43 p.m. EDT). NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute at San Antonio, Texas. Lockheed Martin Space Systems, Denver, is building the spacecraft. The Italian Space Agency in Rome is contributing an infrared spectrometer instrument and a portion of the radio science experiment. JPL is a division of the California Institute of Technology in Pasadena.

Department of Defense... Pumping Up Partnerships...

Civil and military space programs are now facing a time of transition...

The Defense Department is expanding partnerships with spacefaring companies and nations to maintain the strategic advantage it gains in space, the deputy assistant secretary of defense for space policy said today. Speaking with reporters from the Defense Writers Group, Ambassador Gregory L. Schulte said NASA's final space shuttle flight this week represents "a time of transition" for the civil and military space programs. "Space," Schulte said, "is increasingly congested, contested and competitive."

The Omaha, Neb.-based U.S. Strategic Command, whose mission now includes warning companies and countries when space debris threatens their satellites, is tracking more than 22,000 objects in space, he said. A range of countries are developing counter-space capabilities, including satellite-damaging jammers and lasers, he added, and 11 countries now operate 22 launch sites.

"The United States is not the only player in space," Schulte said, "and space is certainly not our private domain. Space is ubiquitous in the defense establishment and in the conduct of military operations, he added, "and we're acting to maintain our strategic advantage in space." Space is critical to ground navigation, smart bomb precision, and to relay unmanned aerial vehicle feeds to troops, Schulte said. Space also is necessary for early warnings of missile launches and for keeping the president connected to U.S. nuclear forces. Space is a force multiplier, Schulte added. "Without space capabilities, we'd need a lot more bombs to put on a particular target and there would be a lot more casualties and collateral damage. Without space assets, we'd need a lot more troops on the ground doing counterinsurgency operations."

To maintain the advantage, Schulte said, "we just launched [the] second in a series of GPS satellites that's going to give us more jam resistance and better civil capacity." The Defense Department recently launched a new space-based infrared satellite, the first in geosynchronous orbit, that will offer much better tactical intelligence for missile launches, Schulte said. DOD also is putting into orbit the first of four advanced extremely high frequency, or EHF, communications satellites, he said, and a new space-based surveillance satellite that will boost the ability to track objects in space.

[img]http://www.satnews.com/images_upload/1595656532/WidebandGlobalSATCOM.jpg[/img]
Artistic rendition of the Wideband Global SATCOM

"Our military space program is going to have to provide us that strategic advantage in a tight budget environment," he added, "and the [DOD National Security Space Strategy] shows a way to do that." The strategy, issued by then-Defense Secretary Robert M. Gates in January and affirmed by Defense Secretary Leon E. Panetta, "seeks to address ... new challenges by promoting norms of responsible behavior in space and sharing data to help promote spaceflight safety," Schulte said. The document also calls for partnerships with the commercial sector and with foreign partners to augment U.S. capabilities, he said, and to increase the resilience of U.S. satellite constellations against attack or disruption. International partnerships that show the way to the future, the ambassador said, involve the advanced EHF satellite, in which three other countries participate, and a Wideband Global SATCOM System, in which Australia participates. Such collaboration, Schulte said, "shares the burden, gives us enhanced coverage and helps provide some deterrence" to those who might consider using counter-space technologies against space assets.

"Another illustration of the way forward," Schulte said, "is a program that our Defense Information Systems Agency, DISA, has proposed to Congress." The program is called ASSIST, for Assured SATCOM Services in a Single Theater, which is the U.S. Central Command's area of operations. "DISA is proposing to commercially procure satellite services to support the warfighter, rather than just leasing the services year to year," the ambassador said. "In doing so," he added, "we can save significantly on annual leasing costs and we can also get access to satellites that have three times the capacity of the closest U.S. government-owned satellite."

The Defense Department also is beginning to work with commercial space companies to reduce the department's costs and to help energize the industrial base. "We're going to see space increasingly commercialized," the ambassador said. "The cost of entry into space is going to go down, and that has all sorts of implications for the Department of Defense, along with opportunities." Next month, for example, the U.S. Air Force will use the commercial space company Orbital to launch the CHIRP sensor — the Commercially Hosted Infrared Payload, Schulte said. "This is a sensor the Air Force purchased and will be launched on a commercial communications satellite to demonstrate an advanced infrared imaging capability," he said, at considerable savings. "CHIRP is costing us something like $65 million and we get 80 percent of the requirements," Schulte said. "If we had launched it as a free-flying satellite, it would have cost more like $500 million." Commercial space is part of the future, he added, "and we want to be part of that future."

The Defense Department is working with NASA, the White House and others to develop a new space transportation policy to update the 2004 presidential policy, he said. "The new policy will reflect the end of the shuttle program but also that there are potential new entrants into space launch, and that our ranges are not only used for national security missions, but also increasingly for commercial missions," Schulte said.

SpaceX is another space transportation company that works routinely with the Air Force range at Patrick Air Force Base at Cape Canaveral, Fla., he added. "Industry has read this strategy and has come to us with all sorts of ideas about innovative approaches to taking advantage of commercial capabilities and thinking differently about space," Schulte said. "And we welcome that." (Source: American Forces Press Service, Cheryl Pellerin)

Astrium... Express Delivery

This satellite is now en route to Baikonur for a scheduled August launch...

The Express AM4 satellite, designed and manufactured by Astrium teaming with Khrunichev for RSCC, has left Astrium’s facility in Toulouse, where it had undergone its final integration and test campaign. Express AM4 will now be transported by a Russian Antonov aircraft to Baikonur, Kazakhstan, in preparation for its launch by a Khrunichev Proton Breeze M vehicle in August 2011. Express AM4, to be positioned at 80 degrees East, is the largest Express satellite ever ordered by national Russian operator RSCC. This telecommunications satellite is built in the frame of a partnership between the European spacecraft manufacturer Astrium and the Russian company Khrunichev Space Center.

RSCC is focused primarily on the development of satellite communications for fixed and broadcast services in the Russian Federation to secure the common information network across the country. RSCC currently operates 11 satellites from 14 degrees West to 140 degrees East in geostationary orbit, and is currently looking for high power satellites to complement its existing fleet and fulfil growing needs for satellite capacity. Express AM4 is the first and major milestone in this ambitious program. Express AM4 is based on the highly successful Astrium’s Eurostar E3000 satellite design. The satellite will be delivered in orbit by Khrunichev Space Center using the Proton launch vehicle. Launch and Early Orbit Phase operations will be conducted from the Astrium spacecraft control centre in Toulouse. Express AM4 has a 63 active transponders communications payload operating in -L, C-, Ku- and Ka-bands for its planned 15-year service life in orbit. Its 12 antennas will provide high performance coverage over the Russian Federation and the CIS countries and its steerable antennas can be used to provide communication to any point within the satellite’s visibility. With an electrical power of more than 16 kW, Express AM4 is the most powerful satellite ever built in Europe. Express AM4 will become the 50th Eurostar satellite to reach geostationary orbit, with Astrium’s Eurostar series having accumulated more than 400 years of successful in-orbit operations.

ViaSat... Review Completed + Now Prepping For Shipment

ViaSat Inc. (NASDAQ: VSAT) has announced that the construction of the ViaSat-1 high-capacity satellite is complete.

Tthe spacecraft is now being prepared for shipment to the Baikonur Cosmodrome in Kazakhstan. ViaSat-1 is now scheduled for launch by International Launch Services (ILS) aboard a Proton rocket during the last week in September. The expected summer launch of ViaSat’s transformational Ka-band satellite was recently delayed when a solar array onboard the Telstar 14R communications satellite failed to fully deploy following its launch in May. Telstar 14R, like ViaSat-1, was built by Space Systems/Loral (SS/L) and uses many of the same solar array elements. An extensive, independent review of the solar array design, manufacturing, and operation was convened by SS/L, which resulted in a set of inspections, tests, and corrective actions for subsequent SS/L satellites, including ViaSat-1. That work is now complete on ViaSat-1 and the satellite has been declared ready for flight.

“We have been working closely with ILS to fit ViaSat-1 into a busy launch schedule that was disrupted by the delay,” said Mark Dankberg, chairman and CEO of ViaSat. “The satellite is now complete, the spacecraft is being prepared for shipment, and a final launch date will be confirmed very soon.”

A ViaSat-1 launch information page has been added to the ViaSat website. Visitors can view mission information, news updates, links to partner sites, and a live broadcast on the day of the launch. ViaSat-1 is designed to transform the economics and quality of service that satellite broadband can provide, with the capacity to serve the accelerating growth in bandwidth demand for multimedia Internet access over the next decade. The high-capacity Ka-band spot beam satellite has planned coverage over North America and Hawaii, enabling a variety of new, high-speed broadband services for WildBlue in the U.S. and Xplornet in Canada. With a capacity estimated at 150 Gbps, ViaSat-1 is expected to be the highest capacity satellite in the world.[/url]

Northrop Grumman + Raytheon... Timely Trajectory Tracking

When split seconds count, this system passed its acquisition test...

The Space Tracking and Surveillance System (STSS) demonstration satellites successfully acquired and tracked a short-range, air-launched target (SRALT) July 8th in a test that showed their ability to track dim objects that have extremely short flight timelines. The satellites were built by Northrop Grumman Corporation (NYSE:NOC), prime contractor, and Raytheon Company, sensor payload provider, for the U.S. Missile Defense Agency (MDA). The exercise verified target capabilities and did not involve an intercept attempt.

"Air-launched targets have a wide variety of trajectories. There's nothing predictable about their flights. The STSS demonstrators successfully tracked this target and collected key data about test conditions and the dynamics of air-launched targets that will be valuable for MDA's predictive capability," said Doug Young, vice president of missile defense and missile warning programs for Northrop Grumman's Aerospace Systems sector.

One single-stage, solid-fueled rocket was drop-launched from the rear of a C-17 cargo aircraft by MDA over the Pacific Ocean Test Range near San Nicolas Island off the Central California coast. The SRALT was selected as a target because it closely replicates realistic engagement scenarios. "This was the first time the STSS sensors have been tested against air-launched targets, and they performed flawlessly," said Bill Hart, vice president, Raytheon Space Systems. "Against such short-range targets, split seconds count. That's why a near-immediate reaction system like STSS is so important to our national defense."

Plans call for the STSS satellites to continue on-orbit testing by participating in a series of performance demonstration tests with ground, airborne, resident space objects and ballistic missile targets to reduce the risk of an operational constellation of space-based sensors for missile defense. According to MDA, the additional flight tests will demonstrate the ability to track various targets, providing critical demonstrator performance characterization while progressing towards closing the fire control loop with Ballistic Missile Defense System (BMDS) interceptors using space-based infrared tracking. MDA is operating STSS as an experimental space layer of the BMDS. Using sensors capable of detecting visible and infrared light, the STSS satellite constellation is part of a collection of land-, sea-, air- and space-based BMDS sensors. They are gathering critical engagement conditions and empirical measurement event data, among other missions.

Boeing.. Spatial Quarters Queued Up (Spacecraft)

The first steps have now occurred for this new space transport system...

Boeing [NYSE: BA], on May 19th, completed the Delta System Definition Review (SDR) of the company's Crew Space Transportation (CST)-100 space capsule design. The milestone follows NASA’s award of a Commercial Crew Development Phase 2 (CCDev2) contract to Boeing in April. The daylong review included representatives from NASA, the Federal Aviation Administration, and independent consultants. They examined the changes made to the CST-100 design since the initial SDR, which was conducted in October under the original CCDev agreement.

Boeing engineers reviewed major spacecraft subsystems -- including structures, thermal, electrical, propulsion, life support, software and avionics -- as part of the Delta SDR, and reached agreement during the review on a single integrated, consolidated baseline design. The Boeing team also was able to show strong alignment between the current design and NASA's draft Commercial Crew Program Requirements. The Delta SDR enables a common understanding of the design baseline as the team progresses toward a system-level Preliminary Design Review (PDR), which will further mature the system design and ensure it meets all requirements. Under the second round of NASA's Commercial Crew Development Space Act Agreement, Boeing expects to complete its System PDR no later than early spring 2012.

Boeing is preparing to gather performance data on the spacecraft's launch abort system and service module fuel tank; evaluate vehicle ascent performance in wind tunnel testing; and build on earlier landing air bag and parachute demonstrations with more in-depth investigations. With firm requirements and adequate funding, Boeing plans to conduct test flights in 2014 and 2015 to support operations beginning in 2015. Boeing's Commercial Crew Transportation System (CCTS) includes the CST-100 spacecraft, launch services and ground systems. The CST-100 is a reusable capsule-shaped spacecraft that has a crew module and service module. The CST-100 relies on proven materials and subsystem technologies and can transport up to seven people, or a combination of people and cargo. The CCTS will provide safe, affordable access to the International Space Station and other destinations in low Earth orbit, and will enable NASA to focus on deep space exploration missions. In addition to its support to NASA, Boeing also plans to supply the CST-100 to Bigelow Aerospace for that company’s inflatable space station. Boeing will also work with Space Adventures to sell unused seats.
