Title: Method and apparatus for predicting impending service outages for ground-to-satellite terminal in a satellite communication system

Abstract: A method (1300) and apparatus (300) combines a terminal blockage profile for a ground-to-satellite terminal with satellite location and motion data for one or more satellites (12) in a satellite communication system (10) to predict an impending service outage or impairment on a real-time or near real-time basis and reports such impending outages or impairments, and the expected duration thereof, to the terminal operator. The prediction of an impending outage or impairment also can include analysis of information concerning atmospheric conditions in the vicinity of the terminal location as well as other potential sources of a service outage or impairment.
