The ViaSat-1 satellite's launch is about to be delayed — to August or perhaps September. Space Systems/Loral, the manufacturer, wishes to initiate a review due to a satellite malfunction with Telstar 14R. And what does that have to do with ViaSat-1? The ViaSat satellite uses similar components and the review will take some time. Originally expected to launch this month, ViaSat-1 is a Ka-band craft that will have the highest capacity of any current satellite as well as highly cost efficient, offering high speed data links on higher frequency bands. It is also expected that the satellite will also greatly assist the Company's JetBlue Airways partnership, with talks ongoing with other carriers for in-flight broadband connectivity contracts. ViaSat-2, their next spacecraft, is hoped to be ready for launch in early 2015, but that would probably only occur only if ViaSat-1 launches soon.

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]

Satellite Delays Cost ViaSat, But Defense Business Remains Solid[/size]
By Peter B. de Selding

    PARIS — Satellite broadband equipment and services provider ViaSat said it is continuing to lose subscribers to its WildBlue commercial satellite broadband service because of delays in the launch of ViaSat's ViaSat-1 satellite. The company is also incurring ground-segment costs for ViaSat-1 even though the satellite will not be in operation until December.

    Carlsbad, Calif.-based ViaSat said its business with the U.S. Defense Department, focused as it is on high-priority areas like facilitating broadband access, appears protected from spending cuts, especially since a large portion of the work is already under firm contract.

    In an Aug. 5 conference call with investors, ViaSat said that while its commercial broadband business has taken several blows related to the delays in the launch of ViaSat-1, results of testing on ViaSat's new consumer broadband terminal, the Surfbeam-2, show it can deliver even higher throughput than forecast.

    ViaSat Chief Executive Mark Dankberg said ViaSat this autumn will begin deploying SurfBeam-2 terminals in the western United States in a kind of broad-scale test drive to see just how much throughput it can offer WildBlue subscribers for no increase in monthly fee.

    Dankberg said early indications are the terminals will be able to more than triple or quadruple the throughput of the first-generation WildBlue terminals. The new-generation Surfbeam-2 gear will operate with WildBlue's two existing satellites, the ViaSat-owned WildBlue-1 and the U.S. Ka-band beams aboard Canada-based Telesat's Anik F2 satellite.

    In the conference call, Dankberg said deploying SurfBeam-2 this fall "will be a junior version" of what the company will provide when its ViaSat-1 satellite is in operation. ViaSat's SurfBeam-2 terminals are also being used for Paris-based Eutelsat's Tooway consumer-broadband service, which is expected to take off in the coming months with the new Ka-Sat satellite declared operational starting last June.

    Dankberg said Tooway subscriber additions appear to be meeting expectations so far but that mass deliveries of terminals had not yet started, creating an inventory backlog at ViaSat that he said should soon be turned into revenue.

    The $400 million ViaSat-1 program was supposed to start commercial operations this summer, a date that was pushed to September and then to December. ViaSat has begun incurring charges related to ViaSat-1 including a terrestrial fiber-backhaul network, gateway Earth stations and a data center, all of which are operational even if ViaSat-1 is not.

    ViaSat Chief Financial Officer Ronald G. Wangerin said during the call that the company spent $15 million over the past six months on expenses that had been committed before ViaSat-1's problems were known.

    The latest delay was due to an alert by satellite builder Space Systems/Loral of Palo Alto, Calif., following a failed solar-array deployment on a Loral-built satellite launched in late May. It was not until mid-July that Loral and ViaSat, along with the ViaSat-1 insurance underwriters, concluded that the defect was a one-off issue on a single satellite and would not affect ViaSat-1.

    ViaSat-1 is now scheduled for launch Sept. 30 aboard an International Launch Services Proton vehicle from Russia's Baikonur Cosmodrome in Kazakhstan.

    Because the current WildBlue service has no available capacity on beams where demand is highest, ViaSat and WildBlue have had to cap their subscriber count, sacrificing new customers. The company — ViaSat acquired WildBlue in 2009 — did not provide detailed figures for WildBlue during the conference call on ViaSat's financial results for the three months ending July 1.

    But in the 12-month period ending April 2011, WildBlue's subscriber count dropped by 3.5 percent, to 409,000. ViaSat said it has dropped further recently. "We have begun seeing some of the effects of the satellite delay on our subscriber numbers," Dankberg said. "We're seeing some falloff in wholesale gross adds, and some upticks in churn."

    ViaSat's defense business appears to be bucking the trend among suppliers suffering from planned U.S. defense budget cuts. Two main programs already under contract are: the Multifunction Information Distribution System Joint Tactical Radio System for defense aircraft, and the second-generation Blue Force Tracking (BFT-2) program to permit troops to distinguish friend from foe.

    Defense programs are a hefty part of ViaSat's already large backlog, which at July 1 totaled $568.2 million, up 16 percent from where it stood a year ago. New contract awards in the three months ending July 1 totaled nearly $254 million, including a $40 million contract from Thales Alenia Space of France and Italy to provide Ka-band feeder links for the second-generation Iridium Next mobile satellite constellation; and a total of $39 million in orders from Boeing as part of the Boeing-led Mexsat satellite system for the government of Mexico.

    ViaSat said its aeronautical broadband business, which began as a mainly commercial-market endeavor, is now seeing more installations aboard government aircraft — manned and unmanned — than on commercial aircraft.

    Ground-based government users will not be far behind, Dankberg said. The company has tested a portable broadband terminal with U.S. special forces using Eutelsat's Ka-Sat, and "it got really, really good results," he said.[/size]
