Satellite coverage region detection

摘要

A system and method for determining when a moving mobile platform will enter or exit a satellite coverage region. In a preferred form the method involves determining a plurality of boundary coordinates that define a satellite coverage region perimeter. A position of the mobile platform is monitored as the mobile platform moves along a travel path. The proximity of the mobile platform to the satellite coverage region perimeter is determined by periodically comparing the position of the mobile platform to the boundary coordinates.
