Analysis of Systematic Bias of Single Station Time Service
Abstract Starting from the basic equations of single station timing, we analyze the factors that cause systematic bias of timing results. Combining the specific experiments, the influence of satellite clock error and receiver hardware delay is analyzed and some useful conclusions are obtained. The systematic bias caused by satellite clock error for all stations changes with time. However, the systematic bias associated with results caused by the receiver code bias of various stations differs, depending entirely on the value of the different receiver code biases, so it should be corrected carefully in the timing and time synchronization. However, the receiver hardware delay does not affect the frequency stability of timing results, so there is no need to correct it in frequency transfer.
Key words :
