Some Applications of GPS Timing Information,
Abstract
GPS Satellites transmit two independent signals. One is C / A code (course acquisition signal) could be utilized by all civilian users. This service is called as Standard Positioning Service (SPS). Another is P code (precise signal) that could be only accessed by those authorized users. The service is called as precise positioning service (PPS). SPS C / A code users can navigate with accuracy of approximately 100m and timing accuracy of about 250-300 ns (I sigma). Such timing accuracy is not enough for precision time and frequency value transfer. For this reason we must do some research work to improve the SPS C / A code accuracy which SPS users can get. This paper presents our recently progress on timing information analysis, its data processing and its timing and frequency measurement applications.
