摘要
提出观测两个已知点的水平角和垂直角,计算测站三维坐标的两点后方交会原理;给出了待定点点位中误差反误差椭球的长短轴及其在水平和垂直方向上转角的计算公式。编制了相应PC-1500计算机的全部计算程序,供野外作业使用。
The paper describes the principle of two-point resection in which the horizontal and vertical angles of two known points are observed, and three dimensional coordinates of station points are calculated. For unknows points, it gives the mean square error of a point, the major and minor axes of error ellipsoids, and the calculating formula of turning angles in horizontal and vertical direction. The correspondingly calculating programs for PC-1500 computer which provide the use for field operation are compiled.
