Abstract :
Receiver needn´t get to current navigation data and only need to synchronize satellites´ signal. So it need achieve the satellite navigation data from special server. The reference moment have bias when receiver captures satellites´ signal. It was found though analysis there is a connection between positioning bias and reference moment bias. There is a very large positioning bias when the reference moment bias is in the narrow middle area of whole ms. The bias comes from border fuzzy in recovering pseudo range. This paper provides theory basis for research method eliminating these bias.
