摘要
研究了DGPS (差分全球定位系统 )用户对接收到的伪距改正量 (PRC)及伪距改正量变化率 (RRC) ,采用卡尔曼滤波进行预处理的方法 .建立了数学模型 ,通过计算机仿真与验证结果表明 :滤波后用户的PRC精度可达到约 0 .1m (靠近基准站时 )和 0 .6m (远离基准站时 ) .该方法可以有效地提高DGPS用户的定位精度 .
This paper focuses on the predictive processing method of the Kalman filter of the customer in DGPS,based on receiving the pseudo range correction(PRC)and range rate correction(RRC).Mathematical model is set up.The results show the accuracy of about 0.1m(nearby reference station)and 0.6m(far off reference station)at PRC can respectively be attained after the filter,this method can effectively improve the accuracy of the customer by the verification and imitation of the computer.
