分米级广域精密定位系统方案探讨

Discussion on Project of Decimeter-Level Wide Area Precise Point Positioning

阐述了分米级广域精密定位服务系统的基本架构及其关键技术。通过仿真分析得出,在该精密定位服务系统中,单频伪距差分用户定位精度可达1 m;单频载波相位差分用户定位精度可优于1 m;双频载波相位差分用户定位精度可优于0.5 m,达到了分米级定位。

This paper mainly expatiated on the frame and key technology of Wide Area Precise Point Positioning at decimeter-level. Through simulating and analyzing, the conclusion was gained that the positioning accuracy of single frequency with pseudo-range was 1 meter and the positioning accuracy of single frequency with carrier phase was better than 1 meter and the positioning accuracy of double frequency with carrier phase was 0.5 meter.
