About GPS satellites
GPS satellites orbit about 20,200 km up and go around the Earth twice a day. Your phone needs signals from at least four of them to work out where you are.
Each carries atomic clocks. Because of relativity those clocks tick very slightly differently in orbit, and the system corrects for it every day, otherwise positions would drift by kilometres.
GPS satellites in Clamber
You reach this landmark at 698 points. It is landmark 18 of the 21 between the ground and the Moon, which waits at 930 points. Its real height is about 1.6 times that of the previous landmark, One Earth stacked.
Answers are worth 0 to 100 points depending on how rare they are, so even a run of nothing but the rarest answers needs at least 7 holds to get here. A fall drops you to just below the last landmark you passed, so a landmark you have reached can slip away again. See how to play for the full rules.
