The Antenna Beam Pointing System is a novel system and method to point a satellite terminal antenna beams to a satellite in near-circular orbit. Unlike other methods, the system described herein relies on the satellite orbital equations of motion to estimate its position with any precision, using a finite-term algebraic expression, and the satellite terminal position information. The system can point to the satellite as a function of the beamforming capabilities of the phased array antenna or the driving system of a mechanically steered antenna. Satellite acquisition could be attained within one second because of the long-term prediction of the orbital equations of motion with programmed initial orbit conditions and the antenna beamwidth which is wide enough to encompass the satellite uncertainty box in orbit. The system could be used with a beacon signal strength indicator or a correlating signal. The system is also applicable for satellites in elliptical orbits.
