摘要
本文从纵横向误差微分关系导出了平面控制网的相对点位精度计算式,由坐标协因数阵Q_(xx)可以计算出相对于任意控制点、任意方位角和任意边长的相对点位精度,或任意三点间的相对点位精度。
This paper derives the calcalation formula for the relative point position precision of the horizontal control network using the longitudinal and lateral error differential relations. From the coordinate cofactor matrix Qxx, it may calculate the relative point position precision with respect to any control point,any azimuth and any side distance or this precision for any three points.
