ISRO eyes to shrug off setback with Cartosat launch in Dec

ЦитироватьHyderabad, Oct 11 (PTI) The Indian Space Research Organisation plans to launch a satellite on board Polar Satellite Launch Vehicle (PSLV) in December, the first since its unsuccessful mission to orbit a navigation spacecraft nearly one-and-a-half months ago.

The ISRO is getting ready for the Cartosat-2 series satellite mission in mid-December from the Satish Dhawan Space Centre or Sriharikota High Altitude Range (SHAR), an official of the space agency told PTI.

This would be the third satellite in the Cartosat-2 series.

In February this year, PSLV-C37 launched the first Cartosat-2 series satellite along with 103 co-passenger satellites in a single flight.

In June, India's workhorse launch vehicle launched the second one along with 30 co-passenger satellites -- the 39th consecutively successful mission of PSLV.

But a PSLV-C39 flight carrying IRNSS-1H navigation satellite on August 31 was unsuccessful, in what is seen as a setback to ISRO.

"We plan to launch Cartosat-2 series satellite 3 mission, which is a follow-on mission in the Cartosat-2 series with the primary objective of providing high-resolution scene specific spot imagery, in mid-December," the official said.

"There will be a few foreign co-passenger satellites...about 15 to 20 (nano satellites)," he said.

The total number of customer satellites from abroad placed in orbit by PSLV so far is 209, according to ISRO.

ЦитироватьIsro to launch Cartosat 2 sat with 30 nano sats in mid-December

NEW DELHI: After the unsuccessful launch of navigation satellite IRNSS-1H, Indian Space Research Organisation (Isro) is gearing up to launch a remote sensing satellite of Cartosat-2 series along with 30 nano satellites of foreign countries in the second half of December.
Спойлер
Vikram Sarabhai Space Centre (VSSC) director Dr K Sivan said, "Isro will be busy in launching a series of satellites from December onwards. We are targeting to launch Cartosat along with 30 nano satellites of foreign countries in the second half of December."

He said, "The replacement satellite for IRNSS-1A (the first navigation satellite whose three atomic clocks, meant to provide precise locational data, had stopped working last year) will be launched soon thereafter. Both these launches will be from the first launchpad at Sriharikota as the second launchpad will be busy in launching three GSLV rockets, including the Chandrayaan-2 mission in March. "If for any reason, Cartosat launch is delayed in December, it will also stall the launch of replacement satellite IRNSS-1I as both these launches have been planned from the first launchpad."

The three GSLV launches, which will involve two GSLV Mk II and one GSLV Mk III (Isro's fat boy), will be from the second launchpad at Sriharikota. Instead of PSLV (which was used for launching Chandrayaan-1 mission in 2008 ), Isro is using GSLV Mk II for the second lunar mission as the payload is heavier this time (combined launch mass 3,250 kg). The payload will constitute orbiter, lander and rover.

Dr Sivan said, "After the IRNSS-1H satellite failure, corrective measures will be taken in all rockets before the launches." Though the inquiry into reasons for the heat shield glitch is still going on, "initial findings suggested a defect in the pyro elements of the rocket which deal with the stage separation mechanism". The VSSC director said the committee probing the failure of IRNSS-1H launch will submit its investigation report much before the upcoming launches.

He said the faulty satellite stuck inside the heat shield is still orbiting the outer space and is "unlikely to fall into the Pacific Ocean anytime soon". On August 31, PSLV-C39 could not deliver the 1.4-tonne IRNSS-1H in the geo orbit as its heat shield did not get separated minutes after the rocket's lift-off from Sriharikota.

THIRUVANANTHAPURAM: The Indian Space Research Organisation (ISRO) has made improvements to the pyro devices on the Polar Satellite Launch Vehicle (PSLV) whose last mission in August was doomed due to the problems with the separation of the heat shield encasing the satellite. The next mission using the rocket - the PSLV C-40, which will have a Cartosat 2 series satellite as its chief payload - is slated to lift off from the Satish Dhawan Space Centre, Sriharikota, in the second half of December, K Sivan, Director, Vikram Sarabhai Space Centre (VSSC) at Thumba here, said.

''We have not changed the basic design of the pyro devices. It's the same, but we have made some design improvements to add more robustness to the system,'' he said. Sivan said the enhancements will soon undergo tests at the VSSC -  the nodal agency for ISRO's launch vehicles - and the Liquid Propulsion Systems Centre (LPSC), Valiamala. As the name suggests, the pyro elements on a launch vehicle employ charges to separate the payload fairing and release the satellite into orbit. On the PSLV C-39 mission, the mechanism malfunctioned, leaving the IRNSS 1H satellite stuck inside the heat shield.

The integration of the PSLV C-40 will begin at Sriharikota in the last week of November. The first stage has already arrived at the spaceport. "Actually, the failure came as a surprise to us. We never expected it as the pyro design which we use is basically a good one,'' Sivan said. Following August's failed mission, the ISRO had se t up a failure review committee to ascertain the causes. Sivan said the C-39 failure has not had any impact on the PSLV's commercial prospects.

Isro cautious about December satellite launch
Nov 17, 2017, 06.44 PM IST



THIRUVANANTHAPURAM: After the recent failure of PSLV-C39 on August 31 this year, Isro centres here including VSSC and LPSC are doubly cautious. They are focused on the next mission of PSLV-C40 to launch 31 satellites including Cartosat -2ER by December end this year.
Спойлер
...

Though PSLV-C40 was planned for launch in November end, it is now decided to launch by December end after a series of tests. "Preparations are on for the next mission pf PSLV-C40 by next month end to launch 30 satellites at one go including the Cartosat-2ER satellite. It will be a robust launch," Vikram Sarabhai Space Centre (VSSC) director K Sivan had told TOI.

All precautions will be taken to prevent any anomalies, he said. In the previous PSLV launch, there was no design fault. The heat-shield at the top nozzle of the rocket failed to release the satellite into orbit and it could be due to a fault in pyro-techniques, he said.

Normally the heat shield split into two halves at the conical nozzle opens up to release the satellite into the orbit, it failed to open 20 minutes after lift-off, the scientist explained. The heat shield is designed to absorb excessive heat produced by friction against atmosphere during take-off and to protect the components and fuel tanks of the rocket.

"The reason why it failed could be due to some hitch in the pyrotechnic material of the heat shield or probably failure of the springs to trigger the force against atmosphere to open the shield to eject the satellite out. The exact reasons are being ascertained by the 'Failure Analysis Committee of core scientists and the report will be released soon, said a lead scientist at VSSC.

The PSLV-C39 launch was to place the IRNSS-1H, the eighth in the Indian Navigation Satellite series which was a step for the country's self-reliance in GPS. The 1425 kg IRNSS-1H satellite launch was crucial as it was carrying atomic clocks to replace the Rubidium atomic frequency standard clocks that failed to function in the previous IRNSS-1A satellite, he said.

While a VSSC scientist said, the failure analysis report is ready but it will be released only within the Isro centres. Based on its findings and recommendations all precautions will be taken to avert any failure, we are doubly cautious. A series of tests will be conducted before the next mission of PSLV-C40 slated for Dec end, he said.

CANYVAL-X 1 and CANYVAL-X 2 (Tom & Jerry)

The first two, CANYVAL-X 1 and CANYVAL-X 2, have candidly been named Tom & Jerry, and are part of a joint project between NASA and South Korea's Yonsei University. The satellite pair will conduct CubeSat astronomy by functioning as a tandem telescope pair; one satellite will carry the optics and the other, the detector.

 ● CNUSAIL-1

The second ISL project is a CubeSat known as CNUSAIL-1, a 3U CubeSat by Chungnam National University, a solar sail experiment that aims to demonstrate de-orbiting procedures. The 4-kg satellite is expected to have a design life of 3 months.

 ● Kausat-5

Also handled by ISL is Kausat-5, a 3U CubeSat by the Korea Aerospace University. An Earth Observation satellite, Kausat-5 will measure the amount of radiation in Low Earth Orbit (LEO) using an infrared imager, with an expected life of 1 year.

 ● STEP Cube Lab

STEP Cube Lab is a 1U CubeSat developed by Chosun University, and is an experimental satellite meant to help the university determine future missions. This is the first CubeSat designed by the university's Space Technology Synthesis Laboratory (STSL), and will carry various payloads including a variable emittance radiator and a solid propellant thruster.

 ● SIGMA (KHUSAT-3)

SIGMA (Khusat-3) is a 3U CubeSat developed at Kyung Hee University. The third nanosatellite in the Khusat series, the satellite will measure the global magnetic field and radiation. Its payloads include a radiation detector and a magnetometer, and it is expected to last for 3 months.

Excluding these, South Korean universities have developed 7 CubeSats since 2006. Of these, three have served their purposes, while the other 4 have failed due to launch incidents or satellite malfunction.

Yesterday we performed a fit check of PicSat in the QuadPack CubeSat dispenser (on the right).
The dispenser and PicSat will be ship separatly to India where we will put PicSat in the dispenser before the integration on the launch vehicle.

This test allows to avoid discomfiture on the launch pad in case of an external modification of the satellite which may block it in the deployer. For this test, PicSat was almost in flight configuration with a development detector which will be modified in the next days.

SSTL ships CARBONITE-2 and Telesat's LEO-1 for PSLV launch

Surrey Satellite Technology Ltd (SSTL) has shipped two small satellites, CARBONITE-2 and LEO-1, to India in preparation for a late December launch on ISRO's Polar Satellite Launch Vehicle (PSLV) from the Sriharikota launch site.
Спойлер
LEO-1 will be one of two Telesat Phase 1 satellites planned for launch this year that will allow Telesat to start testing key performance parameters of its next generation global LEO constellation. The satellite has a launch mass of 168kg and will be launched into an initial sun-synchronous orbit.  After launch SSTL will complete commissioning of the spacecraft and will perform orbit-raising manoeuvres to achieve the final planned orbit. Command of the spacecraft will then be handed over to Telesat for in-orbit operations using the Ka-band payload.

CARBONITE-2, is a technology demonstration mission owned and operated by SSTL that will demonstrate a low cost video-from-orbit space solution using COTS technologies.  The 100kg spacecraft flies a commercial-off-the-shelf (COTS) telescope and HD video both of which have been adapted for a space environment and integrated into a custom built framework.  The imaging system is designed to deliver 1m GSD images and colour HD video clips with a swath width of 5km.

On 21 November 2017 British company Earth-i signed a contract with SSTL to supply 5 CARBONITE series satellites for a new full-colour video imaging constellation planned for launch in 2019.

CARBONITE-2 is a follow-on mission to CARBONITE-1, launched in 2015. The CARBONITE series of platforms are designed for rapid re-visit constellations providing high resolution images, 3-D imaging and video from space. SSTL is a leading supplier of LEO missions to commercial operators: previous missions include Beijing-1, the 5 satellite RapidEye constellation, Deimos-1, exactView-1, KazEOSAT-2 and the 3 satellite TripleSat constellation.

Notes to editor:

LEO-1 has been previously referred to as LEO-Prototype-1.

DECCAN CHRONICLE. | PATHRI RAJASEKHAR

Published Nov 24, 2017, 7:51 am IST
Updated Nov 24, 2017, 7:51 am IST

The launch will take place at the end of December, 2017 or the first half of January 2018.

Nellore: After a four-month lull following the failure of the PSLV-C39/IRNSS-1H Mission, the Indian Space Research Organisation has been gearing up to launch its Polar Satellite Launch Vehicle- PSLV-C40 with Cartosat - 2 series satellite and a host of foreign satellites including some Indian satellites. The launch will take place at the end of December, 2017 or the first half of January 2018.
Спойлер
Isro scientists have been paying special attention to the current mission in view of the  setback to the PSLV-C39/IRNSS-1H Mission launched on August 31, 2017. It may be recalled that the heat shield of the PSLV rocket did not open though the IRNSS-1H (Indian Regional Naviga-tion Satellite System) satellite reached sub- geosynchronous transfer orbit. This was attributed to malfunctioning of the rocket's payload-fairing pyrotechnics. The snag had left the combined fourth stage-fairing-satellite stack stranded in a lower orbit.

Incidentally, IRNSS-1H was supposed to replace IRNSS-1A, which was the first satellite in the Indian Regional Navigation Satellite System. The replacement has become a necessity in view of the failure of atomic clocks in IRNSS-1A. This letdown by India's most dependable workhorse launch vehicle with 39 successful flights out of a total of 41 to its credit, had left everyone, especially ISRO scientists, unnerved.

In this backdrop, the entire space community across the globe will be observing the launch and its success is crucial for ISRO to restore confidence among international clients waiting to launch their satellites through PSLV, a potential forex garner for the country through the launch of foreign satellites. According to sources in ISRO, the payload of PSLV-C40 is likely to be 30 satellites, including  India's Cartosat - 2 series satellite and two more micro satellites, besides 26 satellites of different sizes and shapes belonging to other countries.

With respect to the primary satellite, Cartosat-2 Series Satellite, it is a follow-up mission in the Cartosat-2 Series with the primary objective of providing high resolution scene-specific spot images for civilian and military applications. It carries Panchromatic and Multi-spectral cameras operating in Time Delay Integration (TDI) mode and is capable for delivering high resolution data. Cartosat-2 Series Satellite will be launched by PSLV-C40 along with co-passenger satellites.

The company, founded in 2010, said it launches tech demo satellites several times a year to ensure they are using the latest and most advanced technology. These advancements are then incorporated into future operational fleet.

The company operates a fleet of earth-imaging satellites, collecting a massive amount of information about the planet.

"We've been very pleased with our working relationship with Antrix Corporation Limited (Antrix), the commercial arm of ISRO. When Planet proposed to send a record-breaking 88 satellites to orbit on a single launch, they accepted the challenge without hesitation, and they delivered," said Karthik Govindhasamy, chief technology officer and executive vice president of engineering at Planet.

"We have a rich history with Planet and we are proud to be a reliable launch partner that they can count on for consistent and timely launches," Rakesh S, chairman and managing director, Antrix, was quoted as saying in the statement.

"The Planet's appetite for launch capacity is impressive and we're excited that the PSLV continues to meet their needs," he said. RS GK DV
