Abstract
A receiver and antenna drive gear unit provide optimal mechanical and electrical pointing of the antenna dish at each of the satellite orbiting in geo-synchronous fashion above the equator, the receiver having the capability of calculating and initially pointing the antenna dish at each of the satellites, and then providing peaking routines under operator control to maximize signal strength. The antenna drive gear unit utilizes a separate motor for each of the azimuth and elevational directions and utilizes circular ring gears and a spur gear to drive the antenna, thereby providing much more accurate and repeatable monitoring and positioning of the antenna unit over extended usage.
