摘要
iGPS测量系统已经在国外航空航天制造与检测、汽车船舶工业设计与制造、大型工业设备安装与检测、逆向工程等领域广泛应用。国内应用则刚刚展开，因对其了解不够深入，测量精度没有进行严格的对比和测试，多数应用于辅助测量任务。基于上述现状，本文分析了iGPS系统的测量与坐标解算原理，并分别对系统建站精度、静态单点内符合测量精度、与其它坐标测量系统的坐标转换精度以及不同运动状态下系统的动态测量精度进行了实验测试，得到了有关系统精度的可靠结论。
iGPS measuring system has been widely applied in various fields at abroad, such as aerospace manufacturing and testing, marine industries, installation and test of large -size industrial equipment and reverse engineering. However, the system is mainly used for assistant measuring in China for lack of necessary knowledge and rigorous comparison and test of measuring accuracy. According to the situation, the measurement and coordinate calculation principles of iGPS system are analyzed, and the coordinate system accuracy, static single point measuring accuracy, dynamic accuracy and coordinate transformation accuracy in various situations are tested to reach a reliable conclusion about the system accuracy.
