| 摘 要： | 对于一般用户来说,GPS的动态应用是非常熟悉的,同样的,一个GPS接收机也是一个动态测量系统,然而直到现在,一个GPS接收机的基本观测量(码和载波相位)在处理时,或多或少被当作带有白噪声输入的固定随机偏差过程。文章通过应用动态系统的方法来看待GPS接收机的误差特性,利用一种线型动态空间误差模型针对GPS接收机相关接收中产生的主要误差进行了分析,从而较好地解决了实际经验与理论之间的差异。

| Abstract: | From kinematic GPS applications it is very well known to the users,although up to now the basic observables(code and carrier phase) are treated more or less as a stationary random bias process with white noise input.The objective of the paper is to present a linear dynamic error model in state space for GPS receiver of autocorrelation type.It is tried to close this gap between practical experience and theory by applying the theory of dynamic systems to the error behaviour of GPS receivers. |
