Abstract
Some exception and poor quality measuring data is once existed in the reentry flying of an old satellite,which made a lot of diffculities to the calculation of trajectory determination.In order to solve the problems and give some experience of using this type of data,three different calculation methods are given based on the actual situation of project,including the current statistical modeling Extended Kalman Filter (EKF),the dynamic modeling Unscented Kalman Filter(UKF) and sliding window polynomial Least Mean Square(LMS) estimation.Also the real poor quality measuring data is used to test the three methods and the trajectory calculation results and corresponding impact points are given.The experiences and lessons in the calculation are summarized.The calculation results show that the three algorithms have some obvious differences when the poor quality data is used.So a variety of algorithms are advised to provide reference for each other in a actual project application.The results and experiences have some certain reference value for reentry trajectory determination and real-time estimation of the impact point.关键词
