Accurate localization in combination with wireless sensor networks and laser localization
In order to explore the moon more effectively, it is very important to enhance the ability of navigation and localization of the lunar rover for exploration achievement of scientific goals. In this paper, an Accurate Localization in Combination with Wireless Sensor Networks and Laser localization scheme is proposed. First, the lunar rover position system consisted of the Lander, the lunar rover and a wireless sensor network is introduced. Then, we compare and analyse the advantages and disadvantages of TOA, TDOA, AOA, and RSSI. In the proposed scheme, the wireless sensor networks first localize themselves with the help of the Lander. For increasing the localization accuracy of the sensor nodes, a novel localization algorithm based on APS algorithm is presented. Next, we detail the lunar rover localization especially in that case where the lunar rover is not in the sight of the Lander. In initial experiment, we validate the proposed method using the test platform designed by us.
