In general relativity, gravity changes time. Gravity potential o =-GM/R. Time change r= At/t= AQ / c2. If uncorrected, it would cause errors in GPS Global Positioning System. The GPS satellites orbit average 20,200 km above Earth surface, and gravity at the satellites are a little different from Earth surface. Find the: a) time error r ? e-10 due to gravity. b) distance error (km) in one day. (signal travels at light speed)
