%X On the basis of the motion law in pseudo-range kinematic GPS positioning,three approximation models are discussed and a new approximation model named linear variation of distance among epochs is firstly proposed.The new model is tested and compared with the other two models by use of real-time GPS observations.The result indicates that the model of linear variation of distance is more reasonable than that of linear variation of coordinates,and the approximation model of quadratic curve is the most available for pseudo-range kinematic positioning.
