Abstract :
LEO/MEO satellite systems are playing an increasing important role in future worldwide mobile telecommunications. One of the difficult technical issues encountered in LEO/MEOs is the high speed of these satellites relative to the mobile terminals. Thus, accurate and efficient methods of tracking the satellites are required. In this paper, we propose, analyse and evaluate the performance of efficient antenna pointing algorithms allowing the mobile terminals to track their own movements as well as those of the LEO/MEO satellites
