An antenna positioner includes a housing and a hub mounted within the housing. A substantially planar configured support plate is rotatably mounted on the hub. A substantially elongate antenna is pivotally mounted on the support plate. An elevation drive mechanism is mounted on the support plate and interconnects the antenna for pivoting the antenna a predetermined angle and adjusting elevation of the antenna. An azimuth drive mechanism is mounted on the support plate and interconnects the hub and rotates the support plate relative to the hub a predetermined arcuate distance relative to the hub and adjusts azimuth of the antenna. A controller is operatively connected to the elevation drive mechanism and the azimuth drive mechanism and controls the azimuth and elevation drive mechanisms to adjust elevation and azimuth.

Low profile antenna positioner for adjusting elevation and azimuth

An antenna positioner control system and related method is disclosed. The antenna positioner control system includes a housing and a hub mounted within a housing. A support plate is rotatably mounted on the hub. An antenna is pivotally mounted on the support plate. At least one elevation drive servomotor is mounted on the support plate and interconnects the antenna for pivoting the antenna a predetermined angle and adjusting elevation of the antenna. At least one azimuth drive servomotor is mounted on the support plate and interconnects the antenna for rotating the support plate relative to the hub a predetermined arcuate distance for adjusting azimuth of the antenna. An antenna control unit is operatively connected to the elevation drive servomotor and azimuth drive servomotor and includes an elevation control circuit and azimuth control circuit. Each of the control circuits include a position feedback control loop, a resolver positioned within the position feedback control loop, a rate feedback control loop, a tachometer positioned within the rate feedback control loop, and a motor feedback control loop.
