一种用于电力终端的BDS定位漂移校正算法

摘要

This paper proposes a correction algorithm for the static positioning drift of the BeiDou system (BDS) for power terminals, and carries out experimental verification. Firstly, it introduces the positioning principle and precise single point positioning (PPP), and analyzes the error sources that affect the positioning and positioning drift. Then, according to the experience, some thresholds are set to judge the state of the power terminal, and a moving average correction algorithm is proposed to reduce the late modeling error. The algorithm is implemented by microprocessor and be verified by experiments.%文中提出了一种用于电力终端的北斗系统 (BDS) 静态定位漂移的校正算法, 并进行了实验验证.文中首先简要介绍了定位原理和精密单点定位 (PPP), 分析了影响定位和定位漂移的误差源;然后, 根据经验设定了一些阈值判断电力终端状态, 提出了一种移动平均校正算法, 以减少后期建模误差, 随后通过微处理器实现该算法;最后, 通过实验验证了该算法的可行性.
