摘要
本文讨论了平方根 UDU^T 滤波算法在 GPS 动态用户导航计算中的应用。针对系统测量方程是多维的特点,本文引入顺序滤波概念,给出了适合于动态用户 GPS 导航系统的 UDU^T 滤波算法,还给出了算法的程序框图。在给定飞机航迹情况下,对系统进行了蒙特—卡洛德仿真。仿真结果表明,所提出的 UDU^T 滤波算法适合于动态用户 GPS 导航系统。
A application of square-root UDU^T kalman filter for GPS dynamics user is developed in this paper.First,the sequential filter algorithm is used in this paper,then the square-root UDU^T kalman filter adaptability to GPS dynamics user is deduced.When the airplane trace is given,the Monte-Carlo simulation and analysis are done.The results indicate the square-root UDU^T kalman filter algorithm is satis- factory.
