Abstract
A system and method for aligning an outdoor antenna reflector unit (ODU) with multiple satellites is disclosed. The method may rely on multiple satellites as alignment anchor points to reduce ODU alignment pointing error. The method may require at least three measurements of signal power at different angles for each satellite link to determine the ODU antenna pattern for each satellite link. A peak angle is then calculated for each satellite link based on the determined satellite link ODU antenna pattern. Once the satellite link peak angles are determined, the average peak angle can be calculated and used for aligning the ODU to the multiple satellites. The method may further reduce pointing error by using satellites transmitting within the Kfrequency band as alignment anchor points. The method may simplify ODU alignment by merely requiring an installer to adjust an ODU alignment screw based on the calculated average peak angle.
