The text analyses GPS observation model, the characteristic of kinds of errors fountain and the adopting measures in the observation, and processes the thorough research to Bernese GPS Software Ms-Windows Version 4.2. It makes the most stable satellites as the main error. The differential way adopts non-differential way and double differential way. The positioning precision of the single point is decimeter level. RMS is within 0.01~0.02; If the ambiguity right and without week skip, the observation datum of a EPOCH-BY-EPOCH can make the short base line（S0km）positioning precision reach centimeter level.
