Measurement of the time delay of gps timing receiver based on UTC(NTSC)

GPS provides a method for accurate timing. The measurement of the time delay of timing receiver is a difficult task with the existing method, high in cost and complex in operation. A new and simpler measurement method is presented in this paper, based on the time difference between UTC(NTSC) which is the time scale kept in National Time Service Center and the output of 1pps signal by the GPS timing receiver. On the basis of the international comparison link of UTC(NTSC) and UTC, and the time difference between UTC and GPST, a new method for the measurement of the time delay of GPS timing receiver is given. This method is easy to do. The error of with this method is also analysized.
