Claim:
1. A method for pointing a dual antenna toward a first satellite and second satellite, the dual antenna including a pedestal with mounted first antenna and second antenna, the method comprising the steps of: (a) receiving pedestal location data including pedestal latitude, pedestal longitude, and pedestal altitude for the pedestal; (b) receiving ephemeris data for the first satellite and the second satellite, said ephemeris data including respective satellite latitude, satellite longitude, satellite altitude, and orbit radius; (c) calculating antenna pointings, based on said pedestal location data and said ephemeris data, said antenna pointings including: (d) receiving pedestal misalignment data including pedestal yaw, pedestal pitch, and pedestal roll; (e) calculating corrected antenna pointings, based on said antenna pointings and said pedestal misalignment data, said corrected antenna pointings including: (f) receiving varied yaw, pitch, and roll values; (g) deriving continuously the instantaneous corrected pointings, based on said corrected antenna pointings and said varied yaw values, said corrected pointings including: (h) calculating axis angles for the dual antenna, based on said corrected pointings, said axis angles including for each yaw value: (i) deriving continuously the instantaneous working point axis angles, based on said axis angles, said working point axis angles including for a given yaw, pitch, and roll values:
