EL SEGUNDO, Calif., Nov. 15, 2010 -- Boeing [NYSE] has received the first on-orbit signals from LightSquared's SkyTerra 1 following the satellite's launch at 12:29 p.m. Eastern time on Nov. 14 on an International Launch Services Proton vehicle from the Baikonur Cosmodrome in Kazakhstan. Controllers at the ground station in Hartebeesthoek, South Africa, confirmed initial contact with the spacecraft at 9:50 p.m. Eastern time.

Signal acquisition indicates that the satellite is healthy and ready to begin operational testing and on-orbit maneuvers.

SkyTerra 1 is a Boeing 702HP satellite designed for geomobile services that will provide satellite coverage as part of LightSquared's new broadband mobile wireless network in the United States.

"There is a large and rapidly growing demand for data services to U.S. businesses, individuals and other end users, and Boeing has accomplished the first step in delivering this capability to LightSquared with the successful launch of SkyTerra 1," said Craig Cooning, vice president and general manager, Boeing Space & Intelligence Systems. "Boeing has been designing advanced geomobile satellite systems for the past 13 years, and our experience enables us to provide LightSquared with a high-value solution."

When operational, SkyTerra 1 will combine with ground-based beam-forming (GBBF) equipment and ground stations to form LightSquared's first Space-Based Network (SBN), which will enable faster service and broader access to smaller mobile devices for millions of users in the United States. The Boeing-built SBN will benefit from the satellite's 22-meter L-band reflector, which reduces the need for larger antennas and battery-draining receivers inside mobile handsets.

LightSquared's SBN will combine with a ground network of more than 40,000 base stations built to offer ground coverage, satellite coverage or a combination of the two. LightSquared plans to begin rolling out its nationwide wholesale 4G LTE wireless network in the first four markets in the second half of 2011.

Boeing and LightSquared will soon begin on-orbit maneuvers to move SkyTerra 1 into its test orbit location, where the spacecraft will begin deployments and signal testing. After validating the satellite's subsystems and the SBN with ground stations, LightSquared will accept the SBN from Boeing in early 2011.

Boeing, the prime contractor for LightSquared's satellites, built SkyTerra 1 at its integration and test complex in El Segundo. Harris Corp. of Melbourne, Fla., developed the satellite's L-band reflector. ViaSat's Comsat Laboratories in Germantown, Md., is providing the GBBF equipment, the uplink beacon stations and the ground stations' control and monitoring system. SED Systems of Saskatoon, Canada, is providing the antennas, RF elements and integration services at the gateway stations.

Boeing Wrestling with Antenna Glitch on SkyTerra 1
http://www.spacenews.com/satellite_telecom/101203-boeing-antenna-glitch-skyterra.html

PARIS — The SkyTerra 1 mobile communications satellite launched Nov. 14 for startup wireless broadband provider LightSquared has been unable to fully deploy its large reflector antenna, which is the key enabler for the company's planned U.S. broadband network, industry officials said.

These officials said satellite prime contractor Boeing Space and Intelligence Systems, assisted by antenna builder Harris Corp., has assembled a team to analyze what has happened and to determine whether the antenna unit can be manipulated in some way to permit full deployment.

Officials said that as of Dec. 2, ground teams remained hopeful that the antenna, which when deployed measures 22 meters in diameter and is the largest commercial reflector of its kind ever launched, might be gently "shaken" by ground commands to solve the problem.

"The situation does not look good but it's too early to say whether it's a major issue or something that will be forgotten in a few months," said one industry official. "It's understandable that the satellite control team would want to take its time before deciding on corrective action."

Boeing began deployment of the antenna Nov. 30. A glitch-free unfurling would have taken no more than several hours.

In response to Space News inquiries, El Segundo, Calif.-based Boeing on Dec. 2 issued the following statement: "The SkyTerra 1 satellite, launched Nov. 14, is stable and healthy, and we are proceeding with post-launch checkout processing. As of Dec. 2, the L-band antenna reflector on the SkyTerra 1 satellite has not been fully deployed. Boeing, in close partnership with its LightSquared customer, has assembled a team of experts to assess progress and continue deployment of the antenna. As with any post-launch checkout, it's not unexpected for minor delays to occur, and we are proceeding to complete in-orbit testing and hand over the satellite and its Space Based Network to LightSquared in early 2011."

Reston, Va.-based LightSquared, owned by hedge fund Harbinger Capital Partners of New York, is preparing to use spectrum it has secured for satellite communications to deploy a network of ground-based signal boosters to provide wireless broadband throughout the United States.

The ground-based repeater network, known as an Ancillary Terrestrial Component (ATC), will serve most customers in most places, with the satellite used only when the customer is beyond terrestrial network coverage. But LightSquared's license to use its L-band radio spectrum is conditioned on its maintaining a mobile satellite service.

How tightly the U.S. Federal Communications Commission (FCC) will bind ATC approval to a functioning satellite service is still unclear as the U.S. regulator is still working on a final set of rules that would apply to all mobile satellite ventures planning ATC networks.

SkyTerra 1, which was launched aboard an International Launch Services Proton Breeze M rocket from Russia's Baikonur Cosmodrome in Kazakhstan, is scheduled to enter service in early 2011.

LightSquared will need to deploy thousands of ATC towers to provide nationwide coverage, a multibillion-dollar undertaking that still lacks full financing. Harbinger has supported the company up to now, but has been unable to secure strategic or other partners willing to make major investments of their own.

SkyTerra 1 is insured for about $268 million, a policy for which LightSquared paid a $37.5 million premium. A second, identical satellite, SkyTerra 2, is nearly completed at Boeing and presumably could be launched within a year if needed. It remains to be seen whether insurance underwriters would agree to maintain the company's 14 percent premium rate or would insist on a sharply higher rate in the event that SkyTerra 1's antenna fails to fully deploy.

Alternatively, insurers could insist on rewriting the existing policy to exclude the SkyTerra 2 antenna from coverage. The second satellite is also insured for $268 million.

Melbourne, Fla.-based Harris has become the dominant supplier of the latest generation of large reflector antennas used to provide mobile communications to small devices such as car radios and smartphones. Increasing the satellite antenna size and power means user handsets do not need to generate as much power on their own to capture and maintain a communications link.

The size of these antennas, which unfurl like umbrellas, has increased steadily over the past decade, from 5 to 9, 12, 18 and now, with SkyTerra, 22 meters.

Harris' selling point has been the fact that the antennas, when in stowed position for the satellite's launch, take up a remarkably small amount of volume and weight given their deployed dimensions.

    Typically the antenna is deployed using an articulated boom that locks into position, putting the antenna some distance from the body of the satellite. The antenna itself is then slowly deployed. Videos of the maneuver taken during ground tests suggest a large spider stretching its legs.

    While the technology, developed for U.S. government programs, is considered proven enough to give comfort to insurance underwriters, its commercial adoption has not come without setbacks. The Garuda 1 satellite launched in 2000 with a 12-meter-diameter antenna was found to have a defect that prevented its owner, Asia Cellular Satellite (ACeS) of Indonesia, from making full use of it.

    The 12-meter S-band antenna on the Eutelsat W2A satellite launched in April 2009 and owned by Solaris Mobile of Ireland, a joint venture of Eutelsat of Paris and SES of Luxembourg, suffers from an anomaly that will not permit Solaris to deliver all the services it had planned.

Boeing Completes Skyterra 1 Antenna Deployment[/size]
By Peter B. de Selding

    PARIS — Boeing Space and Intelligence Systems on Dec. 14 announced that the 22-meter-diameter L-band antenna on the SkyTerra 1 mobile broadband satellite had been successfully deployed after a problem that had threatened to torpedo the mission.

    El Segundo, Calif.-based Boeing said that all Skyerra 1 systems are healthy, and that further satellite checkout procedures will continue "over the next several months" before the satellite, which was launched Nov. 14, is handed over to its customer, LightSquared of Reston, Va. LightSquared is owned by New York hedge fund Harbinger Capital Partners.

    "We assembled a core team of experts, and today's success is one that we share with Harris Corporation, the supplier of the antenna, and with our customer, LightSquared," Craig Cooning, general manager of Boeing Space and Intelligence Systems, said in a Dec. 14 statement. "Although the occasional delay in full deployment sometimes occurs on a satellite, it is not a situation we face very often. Today's success is due to the talented men and women at Boeing and their unparalleled expertise in operating satellites and in creatively and successfully resolving the issue."

    LightSquared is building a multibillion-dollar network to provide mobile broadband throughout the United States using radio frequencies available to it only if it maintains a functioning satellite to serve customers outside the reach of its terrestrial network.

    "We congratulate the Boeing, Harris and LightSquared teams who have worked diligently over the past week to successfully deploy the SkyTerra 1 L-band reflector," Martin Harriman, LightSquared executive vice president of ecosystem development and satellite business, said in a statement. "We look forward to Boeing's completion of in-orbit testing of the SkyTerra 1 satellite and handing [it] over to us in early 2011. LightSquared is proceeding on schedule with its rollout of the nation's first integrated wireless broadband and satellite network."

U.S. government revokes LightSquared license

The Federal Communications Commission announced this week it will prohibit LightSquared, a private mobile broadband satellite operator, from beginning service of a high-speed Internet network because it interferes with critical GPS navigation signals.

The ruling comes after a year of extensive engineering tests and political infighting over the LightSquared network, which aims to deliver broadband Internet to 260 million Americans by 2016.

LightSquared launched a dedicated L-band communications satellite, named SkyTerra 1, in November 2010.

But soon after the launch, U.S. government officials voiced concerns that the network's signals would intrude into a spectrum occupied by the Global Positioning System, potentially wreaking havoc on the navigation of military equipment, precision munitions, ships, commercial airliners and private vehicles.

LightSquared proposed deploying a terrestrial network of cell towers to start service, and the FCC granted conditional approval of the plan in January 2011.

The FCC decision was in response to a letter from the head of the National Telecommunications and Information Administration, which studied LightSquared's potential impacts on the GPS signal.

NTIA informed the FCC of its findings in a letter dated Feb. 14.

"NTIA, the federal agency that coordinates spectrum uses for the military and other federal government entities, has now concluded that there is no practical way to mitigate potential interference at this time," said FCC spokesperson Tammy Sun, who released a written statement Tuesday.

"Consequently, the Commission will not lift the prohibition on LightSquared. The International Bureau of the Commission is proposing to (1) vacate the Conditional Waiver Order, and (2) suspend indefinitely LightSquared's Ancillary Terrestrial Component authority to an extent consistent with the NTIA letter," the FCC statement said.

LightSquared, which started to meet an FCC mandate to expand the reach of broadband services in the United States, said it has invested $4 billion in the program, and the company vowed to fight the FCC decision, which came down Tuesday.

The FCC previously granted approval for LightSquared to build its network in 2005.

"At the government's mandate, LightSquared began investing billions of dollars in America's infrastructure тАУ without asking for any money from the American taxpayer," LightSquared said in a statement released Wednesday. "Yesterday, after LightSquared had already spent nearly $4 billion, the FCC changed its mind. There can be no more devastating blow to private industry and confidence in the consistency of the FCC's decision-making process."
