摘要:

实时性和动态性是精密单点定位面临的关键问题。本文基于实时轨道钟差改正产品,讨论了GPS/BDS实时精密单点定位数学模型及误差处理方法。搭建嵌入式软硬件平台,研制出一套具有实时GPS/BDS双系统高精度定位功能的嵌入式设备。测试结果表明,对于嵌入式GPS/BDS实时精密单点定位,静态条件下平面方向优于3 cm,高程方向优于8 cm;动态条件下平面方向优于12 cm,高程方向优于15 cm。

Abstract:

Real-time positioning and dynamic positioning are the key problems of precise point positioning.Based on the real-time track and clock correction product,the mathematical model and error processing method of GPS/BDS real-time precise point positioning are discussed in this paper.Embedded hardware and software platform is built and an embedded device with real-time GPS/BDS dual system,high-precision positioning function is developed.Test results show that for embedded GPS/BDS real-time precise point positioning,the horizontal direction is better than 3 cm and the elevation direction is better than 8 cm under static conditions,the plane direction is better than 12 cm and the elevation direction is better than 15 cm under dynamic conditions.

Key words: real-time precise point positioning, embedded system, GPS/BDS, real-time track and clock product
