Original solutions for localization and navigation on the surface of Mars planet

New original algorithms for navigation on the surface of Mars planet, especially as applied to astronauts, are proposed in this paper. ¹²The autonomous navigation system for astronaut is based on inertial measurement unit (redundant) and Laser (redundant), this permit to localize and navigate in known environment and unknown environment constructing its map in real time, using SLAM robust adaptive algorithms. The estimation of the position of astronauts is done using non linear adaptive filters, such as the Extended Kalman Filter (EKF) and other non linear variant filters. For Mars exploration, these tools are necessary and important for safety in all the future missions. This approach answers the problem of how to extend the existing solutions of localization and Navigation on the earth to Mars surface, according to changes of the magnetic field, gravity and orbital parameters.
