master antenna distribution system

Autonomous celestial navigation system is a typical nonlinear,non-Gaussian dynamic system.

针对传统的扩展卡尔曼滤波不适于非线性和噪声非高斯分布的系统,和一般粒子滤波存在的粒子退化等问题,提出了一种将RJMCMC(可逆跳转马尔可夫链蒙特卡罗)算法应用于月球探测器自主天文导航粒子滤波器中的新方法。

This dissertation taking near earth satellite as research object, systematically studied the method of satellite autonomous celestial navigation based on multi-sensors, the application of nonlinear filtering method in satellite autonomous navigation system and its DSP reali.

本文以近地轨道卫星为研究对象,着重研究了基于多姿态敏感器的卫星自主天文导航方法及非线性滤波方法在卫星自主导航系统中的应用,并对自主导航算法的DSP实现、DSP计算结果的实时图形显示等问题进行了研究。
