基准站坐标偏差对伪距差分定位的影响研究

The Study of the Influences on Pseudo-range Difference Caused by Coordinates Deviation of Base Station

从伪距差分定位的双差公式出发,详细推导了基准站坐标偏差对流动站定位结果的影响公式。实验结果表明,基准站坐标偏差的差值将被直接传递给流动站的定位结果中,从而证明了理论上推导的公式的正确性。所得结论对利用伪距差分定位具有重要的参考价值。

Based on the pseudo-range differential positioning double-difference expressions,the formulas of influences on the result of move station which is owing to coordinates deviation of base station is presented in this paper. The result of a test indicates that base station's coordinates deviation is handed on the position result directly and thus proves the formula is right.The given conclusion provides valuable references for pseudo-range differential positioning.
