Abstract: A satellite tracking system and method, a three-point peaking technique is used to determine the direction of a satellite 50 which includes a signal source. A Kalman filter is used to minimize the effects of noise in the received signal during the three-point peaking operation. This determination may be made at any time. Once the position of a satellite 50 has been determined twice over a time interval, its future position may be estimated by an adaptive continuous step track technique, using a Kalman filter, which assumes that the satellite moves uniformly with time as viewed from the antenna.
Abstract: A dual reflector earth station antenna (ESA) system for transmitting uplink in a first frequency band and receiving downlink in a second frequency band, the ESA system comprises a reflector; a reflector tracking assembly coupled to the reflector and configured to control the direction of the reflector; a feed horn coupled to the reflector and optimized for a near-constant phase center for both the first frequency band and the second frequency band; a subreflector tracking assembly including a subreflector, configured for tracking in the X, Y and Z-axes and supported proximate a focal point of the reflector; and a control system in communication with the subreflector tracking assembly and comprising at least one processor.
