摘要
本文从前方交会点的坐标计算公式出发,推导出双点后方交会坐标的计算公式。根据误差传播定律推导出点位中误差更精确的计算公式。
In this paper, a calculating method of unknown points' coordinates in double resection is given by using the formulas of forward intersection. On the basis of the propagation law of errors the more accurate formulas of calculating position mean square errors are derived.
