三星GPS接收机全地形RTK测量精度测试与应用的探索

将GPS,GLONASS、北斗(COMPASS)3种全球定位系统的接收功能集于一身的GPS接收机(以下简称:三星GPS接收机),能接收18颗以上卫星的定位信息,观测条件相对差时,在导航定位、RTK测量方面表现出巨大优势。本次测试中海达公司生产的H32,在各种观测条件下进行RTK精度测试,并对成果精度和观测地形进行对比分析。可以看出,环视图上,被建筑物遮挡50%以内,可完全正常作业;遮挡50~70%,能够得出固定解,但PDOP值会明显增大,可靠性降低。在城市、野外控制作业将降低对点位的要求,对减轻航测外业像控测量的工作量意义重大。

Exploratory Testing and Application of all Terrain Measurement Accuracy of Tri-Satellite RTK Receiver

The GPS, GLONASS, Beidou ( COMPASS) GPS receiver functions of three global positioning system in one receiver (hereinafter referred to as:Tri GPS receiver), the receiver can receive the satellite positioning information increased to more than 18, the observation conditions relatively poor, in navigation and positioning, RTK measurements showed great advantage.This test Zhong-haida company production of H32, RTK precision test in observation in different conditions, and the accuracy of the results and the observation of terrain analysis, concluded:Ring view, by the building block within 50%, but completely normal operation, block 50-70%, can get the fixed solution, but the PDOP value will increase obviously, reliability reduce.In the city, the field control survey operation will reduce the position requirements, control survey to reduce the aerial survey as the workload of great significance.
