Which navigational error is caused when GPS satellites experience less spacetime curvature?

💡 Explanation

Satellites at higher altitudes experience less gravitational spacetime curvature, so time passes faster; General Relativity predicts this. The GPS requires extremely precise time measurements, therefore, because the satellite on-board clocks run slightly faster, the signal delay is underestimated rather than navigational inaccuracies arising from other propagation errors.
