摘要
Abstract
To improve the performance of ultraviolet sensor applied to middle and high orbit transfer spacecraft,an autonomous navigation scheme based on ultraviolet sensor is proposed.By observing the ultraviolet image of earth with sensors,geocentric vector information is provided and then the orbit of the spacecraft can be determined.The scheme is designed without range measurements,since range error to earth is too huge to use during orbit transfer from height 1 000 km to 36 000 km.The algorithmic model is established,and simulation is taken using extended Kalman filter with orbit data and measurement data.Apart from the influence of sensor measurement precision,sampling period on the navigation accuracy is studied,and observability properties are investigated.The simulation results show that the scheme is effective and the navigation filter can also converge to acceptable accuracy.关键词
