Abstract:In this paper, we address the issue of the integrated navigation algorithm with different combination of measurements for Mars orbiter. First, system dynamic model and navigation measurement models using optical measurement information, radio measurement information and X-ray pulsars measurement information are respectively established. Second, optical/radio/pulsars integrated navigation algorithm is proposed, and observability analysis of the integrated navigation system is also conducted. Third, adaptive extended Kalman filter is adopted to fuse measurement information and suppress measurement and process noise to optimally estimate the state of Mars orbiter. Monte Carlo simulation results show that optical/radio/pulsars integrated navigation can effectively improve the navigation accuracy and satisfy the navigation requirements of Mars orbiter. © 2018 COSPAR
