Third Lockheed Martin-Built GPS III Satellite Now Climbing To Orbit


Reading time ( words)

After a successful launch this afternoon, the third Lockheed Martin-built GPS III satellite is now headed to orbit under its own propulsion. The satellite has separated from its rocket and is using onboard power to climb to its operational orbit, approximately 12,550 miles above the Earth.

GPS III Space Vehicle 03 (GPS III SV03) is responding to commands from U.S. Space Force and Lockheed Martin engineers in the Launch & Checkout Center at the company's Denver facility. There, they declared rocket booster separation and satellite control about 90 minutes after the satellite's 4:10 p.m. EST launch aboard a SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station, Florida.

"In the coming days, GPS III SV03's onboard liquid apogee engines will continue to propel the satellite towards its operational orbit," said Tonya Ladwig, Lockheed Martin's Acting Vice President for Navigation Systems. "Once it arrives, we'll send the satellite commands to deploy its solar arrays and antennas, and prepare the satellite for handover to Space Operations Command."

After on-orbit testing, GPS III SV03 is expected to join the GPS constellation – including GPS III SV01 and SV02, which were declared operational in January and April – in providing positioning, navigation and timing signals for more than four billion military, civil and commercial users.

Lockheed Martin designed GPS III to help the Space Force modernize the GPS constellation with new technology and capabilities. The new GPS IIIs provide three times better accuracy and up to eight times improved anti-jamming capabilities over any previous GPS satellite. They also offer a new L1C civil signal, which is compatible with other international global navigation satellite systems, like Europe's Galileo, to improve civilian user connectivity.
