We currently have over 30 GPS satellites orbiting the Earth at around 20,200 kilometers or about 12,550 miles above us, with at least four always visible from any point on Earth's surface.

SpaceX launched a new GPS satellite to orbit for the US military, ... (20,200 km) above the Earth’s surface, where more than 30 GPS satellites are currently operating.

LITTLETON, Colo. — A new factory built to crank out the next generation of advanced Global Positioning System satellites will draw upon some Hollywood magic: 3D glasses and virtual reality.

The path to our current GPS constellation was paved in the early 1970s by the Naval Research Laboratory’s NTS-1 and NTS-2 spacecraft which were revolutionary game-changers.

Called R-GPS for short, the program is intended to provide an alternative, backup network for the current satellite system. "[GPS is] vitally important to everything we do day-to-day, from the ...

The lab and the Space Force are also considering how the satellite could augment the current GPS constellation as standalone small satellites. The program’s scope also includes development of NTS-3 ...

The GPS time scale doesn't use leap seconds. However, part of the data transmitted by the satellites is the current offset between GPS time and UTC. Most GPS receivers apply the offset and output UTC.

The Space Force has around 31 operational GPS satellites in orbit, a mix of modern and older spacecraft providing varying levels of capability. The newest satellites, dubbed GPS III, are built by ...
