| Abstract: | The coordinates of an end point are required to be known in solving the GPS baselines.The precision of the known points has impact on the solutions of the baselines.The effect of the starting point coordinate deviation on GPS baseline surveying is explicated in this paper.According to the double_difference observing equations located by GPS static state relative fixedpvition the mathmatical model is established.By analysing the simulated data,some useful conclusion are obtained.Several methods for improving the known points precision are put forward. |
