Driver software installed on the computer can then read time stamps from the receiver and very precisely adjust the operating systems time so that it coincides with the correct time. The timing receiver can communicate accurate time to a host computer via a serial or USB interface. These very precise clocks can be used by ground-based receivers to obtain accurate timing information.īy utilising a well-located GPS antenna, with built in timing receiver, this can provide a consistent supply of accurate time stamps to a host computer. However, in order to provide precise positioning information, each satellite has a very precise atomic clock installed. It can set your PC time to the precise time from atomic clocks on-board NASA USA GPS satellites which orbit the Earth ! Yes, its amazing what the technology revolution has brought us today.The GPS system is a constellation of 32 polar orbiting satellites primarily intended for navigation and positioning.
