应用紫外敏感器的高轨卫星自主导航技术OA北大核心CSTPCD

In response to the problem of improving the autonomous survival and mission capabili-ties of satellite,and ensuring high-precision autonomous navigation tasks for future high orbit satellites without ground measurement and control station support.a method for autonomous navigation of satellite using the Earth ultraviolet and stellar visible light bands is proposed in this paper.This method uses field of view 1 to observe the stellar visible light bands and field of view 2 to observe the Earth ultraviolet bands.Then,field of view 1 is used to recognize all stellar ima-ges using the global recognition algorithm,and the optical axis direction of the recognition is used as the stellar correction,field of view 2 is used to image the contour of the Earth ultraviolet band and calculate the direction of the Earth center vector in the satellite coordinate system.Through the high-precision system deviation calibration,the current domestic high orbit autonomous navi-gation application has been achieved in high-precision.
