Global Positioning System and Time and Frequency Measurements
Abstract
The Global Positioning System (GPS) has been used for time synchronization among major national timekeeping facilities for nearly ten years. Its reliability and accuracy are well documented. While older GPS equipment has operated well in a laboratory environment, more advanced receivers now on the market provide enhanced performance at a lower cost while expanding GPS time accuracies to new applications. The Collins Air Transport Division of Rockwell International has developed a commercial GPS sensor known as the NAVCORE I which derives position, velocity, and time data from GPS satellite signals. Digital data outputs are updated at the rate of one complete solution per second, making the sensor function applicable to a wide range of dynamic and static time and navigation applications. This paper describes time performance of the NAVCORE receiver and the design of a time and frequency system based on NAVCORE.
