This book a study of the design and simulation of fleet tracking system for multi-beam operation. Fleet tracking system is now one of the most popular technological changes in all over the world that is going to make our personal and business life lot easier. It will be completed in two phases. The first phase will design and simulate the fleet tracking system assuming single beam operation. In the second phase the multi beam scenario will be simulated. The fleet tracking system is an embedded application, which will continuously monitor a moving fleet terminal and report the status.
