摘要
本文综述了转发GPS外测数据处理和状态估计方法。详细讨论了各种处理观测值的差分法,比较了它们的优缺点。由数学仿真证明GPS用于弹道测量时其状态估计的精度是很高的。
This paper summariges the methods for translated GPS extra-traxzctory measuring data and state estimation, discusses in detail various differential methods for processing observation data and compares their advantages and disadvantages. Mathematical simulation showed that it is very high for the accuracy of state estimation to use the GPS in trajectory measurement.
