摘要
精密单点定位技术不依赖移动通信网络,在缺少CORS站和控制点的情况下,一定程度上能够满足特殊行业的测量需求。UBLOX发布的首款面向大众的多频段接收器ZED-F9P,能在给定的时间内接收更多的卫星信号,理论上能够较以往有更高的定位精度。为此我们挑选了集成ZED-F9P的接收机板卡、天线和供电模块,制作了便携式GNSS接收机,用来开展精密单点定位实验。基于RTKLib软件,将多种观测条件下的测量数据进行处理,结果表明:当测量点位在无遮挡条件下,静态连续观测30 min以上,该型接收机平面定位精度优于0.25 m,高程精度优于0.15 m。这种方法实现了低成本便携式GNSS装备的单点定位,为特定行业和地域开展高精度点位测量提供了参考数据。
Precision point positioning technology does not rely on mobile communication networks,where the CORS station and control points are missing,to some extent,to a certain extent,to meet the measurement requirements of the special industry.The first paragraph of Ublox is facing the multi⁃band receiver ZED⁃F9P,which can receive more satellite signals within a given time,theoretically,than conventional positioning accuracy.To this end,we have selected the receiver card,antenna and power supply module of ZED⁃F9P,making a portable GNSS receiver to carry out precision single point positioning experiments.Based on RTKLIB software,measurement data under multiple observation conditions,the results show that when the measurement point is in the case of no shielding conditions,the static continuous observation is more than 30 minutes,the type receiver planar positioning accuracy is better than 0.25 meters,and the elevation accuracy is better than 0.15 meters.The program enables single point positioning measurements of low⁃cost portable GNSS measuring equipment,reference data is provided for high⁃precision point measurements for specific industries and geographies.
