This Final Report summarizes the research activities of the faculty and students at New Mexico State University sponsored under NASA research grant NAG5-7520. This report covers the period between 1 May 1999 and 30 April 2000. Individual copies of the technical reports, theses, and dissertations have been submitted under separate covers as they were completed.

This paper will present work being done to model and simulate a CDMA based Mobile Satellite System architecture for providing all or part of the future Air Traffic Management (ATM) services. Such a system, will help in relieving the dependence on ground based networks, if not eliminate it. Additionally such an architecture can be used in parallel or as a supplementary service along with ground based links to help alleviate any capacity bottlenecks, or in areas where such services are difficult to make available such as in oceanic, remote areas outside the jet highways, or in developing countries where ground services are less available.
