摘要
从车载移动测量系统定姿定位基本原理出发,重点讨论了In-Fusion组合技术的实时导航策略。选取西宁市POS测试数据进行基于In-Fusion Single Base后处理解算精度分析,同时分析GAMS和DMI的影响,测试数据POS定位精度小于2. 5 cm,满足工程测绘精度要求,对车辆移动测量系统进行工程应用起到指导意义。
In this paper,proceed from the principle of position determination of vehicle mobile measurement system,we discussed the real-time navigation strategy of In-Fusion combined technology.And then,we carried out the accuracy analysis of Xining POS test data based on the In-Fusion single Base technology,and analyzed the effects of GAMS and DMI.The positioning accuracy of POS test data is less than 2.5 cm,which can meet the requirements of precision engineering on surveying and mapping.This study can play a guiding significance for engineering.
