利用平稳时间序列模拟接收机钟误差

Simulating the clock error of receiver by the method of linear time sequence

随着GPS应用的扩展以及GPS产业的发展,使得GPS快速、准确地定位成为必然。然而要达此目的,对其定位中的各种误差研究的投入则必不可少。文中在单点定位的基础之上,根据基站上数据的解算结果,对接收机钟误差的改正值进行研究,利用随机过程中的平稳时间序列方法对其进行模拟解算,并最终得出其时间序列的随机模型。

It is necessary to become fast and accurate in GPS positioning, along with extending the application of GPS, and developing of GPS industry. So, we must do much more work on diversified errors of orientation than before. On the base of single orientation, using the station outcomes, research of the clock correction value of GPS receiver is carried out. The method of linear time sequence is used to simulate and calculate it. And finally, we get the random model of time sequence for clock error.
