Lockheed completes antenna assemblies for 8 GPS III satellites

by GPS4US 2013-07-18 18:09
Lockheed Martin says it has completed assembling antennas for the first eight satellites for GPS III, the new system that will replace aging GPS satellites currently in orbit.

Lockheed, the prime contractor in the GPS III effort, delivered seven antennas to their GPS III processing facility on June 14. The antennas will be installed in SV01, the first the first GPS III space vehicle, which is scheduled to be delivered to the US Air Force in 2014. The new antennas will allow SV01 to send or receive navigation data to earth.

GPS III will also be capable of inter-satellite data transfer, telemetry, tracking and control for satellite-ground communication. The antenna assembly is critical for both military and civilian GPS use. They will provide up to eight times more anti-jamming signal power and three times more accurate GPS data compared to the current system.

"These antennas on the next generation of GPS III satellites will transmit data utilized by more than one billion users with navigation, positioning and timing needs," Keoki Jackson, vice president of Lockheed Martin's Navigation Systems mission area, told United Press International.

"We have become reliant on GPS for providing signals that affect everything from cellphones and wristwatches, to shipping containers and commercial air traffic.”
