农业机械导航中的GPS定位误差分析

摘要

GPS定位已在农业机械装备中得到广泛应用,但定位过程会产生一定的误差.导航中GPS定位误差分析,可采用目前应用比较广泛的差分技术及联合卡尔曼滤波算法;在动态定位数据的处理中,利用基于时间序列的处理方式,能显著的降低定位误差.%GPS positioning has been widely used in agricultural machinery equipment.However,during the positioning process,certain errors may occur.The analysis of GPS positioning error inagricultural machinery navigation can adopt the widely used difference technique combined with Calman filtering algorithm.During the processing of dynamic positioning data,using method based on time series can significantly reduce positioning error.
