The clock model is analysed much in this paper which is key to GNSS orbit determination. First it is introduced how to calculate sampling distance. That is necessary and mostly to rebuild the clock model of incept equipment from both GNSS single data of especial PRN codes point positioning and passive ranging system. Then the formula is gived about both clock error model of GNSS and the change from GPST to time of absolute positioning And the express about telegraphese navigation to GPST is taken apart particularly. Last both the process of GNSS amending clock model with telegraphese navigation code and of calculating sampling distance and experience of shorting positioning distance first are given.
