The accuracy with which a GPS receiver can determine your position on the earth depends critically on how accurately it knows the local time on the earth when it receives a signal relative to the time on the satellite when it broadcast the signal. The speed of light is 3x108 m/s, and so in 1 ns (10-9 seconds) light travels 1/3 of a meter or approximately 1 ft. If the clock on a GPS receiver is in error by 1 microsecond, what is its error in determining your position?
