Abstract
The present invention relates to a system and method for monitoring a non-tracking satellite antenna terminal's pointing accuracy in three situations. First, the pointing accuracy is monitored after initial installation of the antenna within a geo-synchronous satellite communications system. Secondly, the method is employed to determine mis-pointing of the antenna terminal as a result of a long term event such as building settlement. Lastly, the method is employed to detect mis-pointing of the non-tracking antenna terminal due to a short term event, such as an earthquake, wind storm, or hurricane.
