摘　　要：目前大型科学工程朝着更大尺寸、甚高精度、不可逆转、海量观测数据及多传感器测量等更复杂的方向发展,进行精密工程三维控制网仿真分析,对高效高精度地建设我国大科学工程具有重要意义。从仪器误差、环境干扰、反射棱镜制作误差以及地球曲率等方面探究激光跟踪仪测量系统的测量数据的误差来源,通过蒙特卡洛坐标不确定度分析要领,计算和评定目标点坐标与测站坐标的误差,并且应用点位误差椭圆对控制网布局进行优化设计。模拟实验表明,相对于经验布局,该方法更易获得符合测量要求的网络布局,对超大规模高精度控制网建设具有一定指导意义。At present,large-scale scientific projects are developing in more complicated directions,such as larger size,very high accuracy,irreversible,massive observation data and multi-sensor measurement.Carrying out simulation analysis of the three-dimensional control network of precision engineering is of great significance for the construction of China's large scientific projects with high efficiency and high precision.Based on the laser tracker measurement system,this paper analyzed the source of measurement data error from the aspects of instrument error,environmental interference,reflective prism manufacturing error and earth curvature,etc.Through the Monte Carlo coordinate uncertainty analysis method,the error between the coordinates of the evaluation target point and the coordinates of the station was calculated.Experiments showed that,compared with the empirical layout,this method was easy to obtain a network layout that standards the measurement requirements and could provide reference for the construction of ultra-large-scale high-precision control network.
