First GPS IIF satellite on station
Officials from the Air Space Command’s Global Positioning Systems Wing at the Space and Missile Systems Center here have announced the first GPS IIF satellite arrived on station Aug. 1. This indicates the satellite is in its designated orbital position and ready for its final phase of on-orbit checkout and testing, to be completed before September. The satellite then will be cleared to serve navigation and timing users as part of the operational GPS constellation.
The next-generation GPS IIF satellites will provide improved accuracy through advanced atomic clocks, a longer design life than legacy GPS satellites and a new operational L5 civil signal that benefits civil aviation and other safety-of-life applications. It also will continue to deploy the modernized capabilities that began with the eight modernized GPS IIR satellites, including a more robust military signal. (…)
