Gps system time (gpst) is defined by the gps ground segment on the basis of a set of atomic clocks aboard the satellites and in the monitor stations. It is not adjusted for leap seconds and it is synchronized with the utc (usno) at nanosecond level. The origin epoch of gps time is 0h utc (midnight) of january 5th to 6th of 1980.
Gps determines distance between a gps satellite and a gps receiver by measuring the amount of time it takes a radio signal (the gps signal) to travel from the satellite to the receiver. Radio waves travel at the speed of light, which is about 186,000 miles per second.
Gps is used for navigation in planes, ships, cars, and trucks also. The system gives critical abilities to military and civilian users around the globe. Gps provides continuous real-time, 3-dimensional positioning, navigation, and timing worldwide.
