GPS网约束平差基准可用性指标研究

针对GPS网约束平差时,高精度观测成果受平差基准影响,导致精度损失这一瓶颈问题,提出了约束平差基准点选择的可用性指标,探讨了一种利用无约束平差验后方差和可靠性分析矩阵,一次性判断全部设计拟重合点的可用性方法。这种方法准确、高效、可靠。

Study on Approve - useful Index about Bount - adjustment Datum of GPS Networks

This paper aims at a difficult problem of accurate losser, in which observation results of the high precision accept the effect of adjustment dotum, as the GPS Networks bound adjust. Approve- useful index of the datum point of the bount adjustment is proposed An accurate, high - efficiency, reliable approve -useful methods are also discussed, which makes use of the tested variance of the no - bound adjustment and the reliability - analytical matrix, by which once all designing coincidence - point is judged.
