The Affordable Tactical Low Altitude Satellite Technology ATLAST program focuses on developing an architecture for a system providing tactical and beyond line-of-sight communications employing a constellation of satellites in Low Earth Orbit LEO. A LEO based approach may result in a cost effective system providing voice and data communications between small, low-power, mobile terminals and hub stations. A constellation of small, inexpensive, lightweight satellites can be launched into LEO at a cost lower than that for higher orbits. Also, using LEO assets requires much less power to close the link. This report presents the approach to designing such a system and summarizes the design. The initial communications requirements are presented, and the impact discussed. Trade-off involving geometries for tactical links are presented. The baseline strawman design is given, including communications link budgets.
