A Planetary Rover Localization Algorithm Based on Wireless Sensor Network

First of all,the existing localization algorithms for planetary rovers are summarized.And then,the RCM(RSSI and Circle centre Mixed localization) algorithm and its theoretical model,which combines RSSI(Received Signal Strength Indicator) algorithm with the excircle center algorithm,are proposed based on the technology of wireless sensor network.Simulation results show that the localization error is reduced to less than 10% even when the error of RSSI algorithm is up to 50%,demonstrating validity of the proposed RCM algorithm.
