Abstract: A method and apparatus for reconfiguring a satellite based on its position relative to one or more reference points on the Earth's surface. The method and apparatus use dot products defining relative locations of the satellite and predefined regions on the Earth's surface to determine when the satellite is within the predefined region. When the dot product comparison indicates that the satellite is located within the predefined region, a computer on-board the satellite executes a stored command set to reconfigure the satellite's communications protocol for the predefined region in which the satellite is located.
