SpaceX Falcon 9 rocket launched the newest GPS III satellite, Space Vehicle 03 (SV03), for the U.S. Space Force (USSF) from Cape Canaveral Space Launch Complex-40 in Florida on Tuesday at 4:10 p.m. EST. The payload separated at 5:40 p.m., 1 hour and 29 minutes after liftoff.

The launch marked the second time a Falcon 9 carried a GPS III satellite into space; SpaceX served as the provider for the first satellite’s launch in December 2018, while the second satellite was launched on a United Launch Alliance (ULA) Delta V rocket in August 2019.

The Falcon 9 first stage booster successfully landed on SpaceX’s droneship “Just Read the Instructions,” about 8 minutes and 30 seconds after liftoff.  This was the first national security space launch where SpaceX attempted to recover the booster post-launch. Walter Lauderdale, mission director for the Space and Missile Systems Center’s Launch Enterprise said in a June 26 media teleconference that the Space Force agreed to give SpaceX the opportunity to recover the booster during this mission in exchange for some revised spacecraft requirements.

The launch took place after a two-month delay from its originally scheduled date  in order to implement new health and safety measures to protect launch and operations crew during the ongoing COVID-19 pandemic.

GPS III SV03 will augment the current GPS constellation of 31 operational spacecraft. GPS satellites operate in Medium Earth Orbit. GPS provides positioning, navigation, and timing services for more than four billion users worldwide. This latest generation of GPS satellite boasts a 15-year design life — 25 percent percent longer than the last generation of GPS satellites on-orbit.

“The GPS III program brings a new standard of excellence for the entire space community. Our production team and contract partners have developed an indispensable tool that is available to military and civil users around the world.” said Cordell DeLaPena, program executive officer for SMC’s Space Production Corps. “Our team will continue to advance the launch campaign for the remaining space vehicles and I anticipate the successful launch of SV03 on the Falcon 9.”
