不同品牌GNSS设备坐标系统参数快速转换方法

Fast Conversion Method of Coordinate System Parameters between Different Brand GNSS Equipments

为提高不同GNSS设备坐标系统参数转换效率,减少现场采集数据时间和手输参数错误率,针对电力工程测绘精度要求高、测量环节多、多种GNSS设备协同使用的特点,山东电力工程咨询院有限公司基于Leica Geo Office 7.0开发了“不同GNSS设备数据转换系统V1.0”,集成了徕卡、天宝、南方等品牌GNSS设备坐标系统参数转换模块,解决了不同品牌GNSS设备之间坐标系统参数不通用、参数文件加密且存储方式不同等技术难题。经实例验证,在保证精度的前提下可有效提高电力工程测绘的工作效率。

In order to improve the conversion efficiency of different coordinate system parameters of GNSS equipments,and reduce the time of field data acquisition and the error rate.For the features of high precise results,too many connections and cooperative use of different GNSS devices in power engineering surveying,Shandong Electric Power Engineering Consulting Institute Corp.,Ltd.developed the"Different GNSS equipments Data Conversion System V1.0"based on Leica Geo Office 7.0,which integrated data conversion modules between GNSS equipments of Leica,Trimble,South,and solved the inconsistency of coordinate system parameters between different brands GNSS equipments,file encryption and different storage methods and other technical problems.The example validation shows that the efficiency of surveying and mapping in power engineering can be effectively improved on the premise of guaranteeing the accuracy.
