GPS IIIF will be the first GPS satellite block to have all space vehicles participate in the Cospas-Sarsat system. The Cospas-Sarsat system is an international collection of satellites spanning low-earth, medium-earth, and geostationary orbit satellites which all listen for 406 MHz distress signals generated by beacons on earth.
The Contingency Operations effort enables GPS III satellites to participate in the GPS constellation, albeit in a limited fashion, without having to wait until OCX Block 1 becomes operational (scheduled for 2022). The United States Space Force awarded the US$96 million Contingency Operations contract in February 2016. [74]
SpaceX is set to launch the U.S. Space Force's GPS III Space Vehicle 04 today from Cape Canaveral Air Force Station in Florida. The launch today will use a Falcon 9 first-stage that hasn't flown ...
Like earlier GPS satellites, Block IIF spacecraft operate in semi-synchronous medium Earth orbits, with an altitude of approximately 20,460 km (12,710 mi), and an orbital period of twelve hours. The satellites supplement and partially replace the GPS Block IIA satellites that were launched between 1990 and 1997 with a design life of 7.5 years ...
As SpaceNews reports, Space Force's Space Development Agency late last month selected 19 separate space companies to participate in HALO, which aims to "accelerate the development of satellite ...

Beginning in 2007, DSCS began being replaced by the Wideband Global SATCOM system. A total of 14 DSCS-III satellites were launched between the early 1980s and 2003. Two satellites were launched aboard the Space Shuttle Atlantis in 1985 during the STS-51-J flight. As of 14 September 2021, six DSCS-III satellites were still operational. [2]
The 3rd Satellite Communications Squadron is a United States Space Force unit responsible for maintaining critical communication for missile warning. It is a part of Space Delta 4 and headquartered at Buckley Space Force Base, Colorado. It was activated on 24 March 2022 after inactivating Space Delta 4, Detachment 1. [1]
