| Abstract: | The design plan of semi-physical simulation system for optics-based autonomous navigation is discussedduring the section of Mars capture and circum-Mars in Mars exploration. By research orbit dynamical model and imageprocess technique, observation model of auto-navigate module and the model of display module are built, and the positionand speed of the detector were calculated by using unscented Kalman filter. It is shown that the accuracy of autonomousnavigation system through simulations is very high. |
