摘要
随着RTK技术的普及,基于RTK加密的GPS工程平面控制网的布设已成为一个具有重要现实意义的技术问题。基于此,研究了控制网的基本单元图形以及实际作业中应如何保证网的精度和可靠性等问题。为了估算控制网的精度,使用蒙特卡罗法得到单位权中误差,并得出具有实际意义的精度指标主要包括边长相对中误差、点位绝对中误差和相对中误差,最后给出了一个基于RTK加密的GPS工程平面控制网的布设实例。
With the popularization of RTK Technology, the problem that GPS plane control network is densified by RTK is becoming important and realistic. The basic unit sketch is studied in this paper. In the meantime, how to guarantee the reliability and accuracy is discussed in practice. In order to assess the accuracy, Monte Carlo method is used to get the mean square error of unit weight, and discussed the main precision index includes： side square error, mean square error of points and relative mean square error between points, at last, given.
