| 摘 要： | 针对地磁场模型精度较低从而导致导航精度不高及基于轨道动力学方程的天文导航方法的局限性问题,提出了一种利用天文,地磁信息进行飞行器自主导航的方法,建立了适用于一般飞行器的动力学方程,并推导了系统的观测方程.该方法以星光与地磁矢量夹角为观测量,采用Unscenteal Kalman Filter(UKF)方法估计飞行器的位...

| Abstract: | According to the low precision of navigation system caused by the low precision of geomagnetic model and the limitation of astronomy navigation based on dynamics models,a autonomous navigation method,which used celestial/geomagnetism information,was presented.A general dynamics models was presented,and the observational equation of the system was educed.The angle between starlight and geomagnetic vectors was taken as observed variables and Unscenteal Kalman Filter(UKF) was used to estimate the position and ... |
