摘要
Abstract
Beidou timing user cannot accomplish precise one-way timing because of l arger changes of uplink delay in Beidou Satellite Navigation System.It is found that the linear Kalman filter algorithm cannot exactly estimate the uplink dela y value when the continuous large wild values appear,which cannot be used norma lly for consumer.So the algorithm is modified and measure is brought forward to estimate the value of uplink delay using Kalman filter algorithm.At the same t ime,the simulation is carried out,and the experimental result indicates that t he algorithm is right.关键词
