Smart Algorithms for Astronaut Localization and Navigation on the Surface of Mars Planet Based on Natural constraints

New original algorithms for navigation on the surface of Mars planet, especially as applied to astronauts, are proposed in this paper. The 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 adaptive algorithms and physical and natural constraints of astronaut's body. 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.
