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. (…)
