Abstract
Systems and methods for optimizing low profile SATCOM antenna panels affixed to a moving vehicle. An elongated SATCOM antenna panel has a narrow azimuth beam optionally having a typical width of no more than a 2-degree angle while the SATCOM antenna panel is maintained parallel to the motion trajectory of a carrying vehicle. An actuation unit rotates the SATCOM antenna panel about three orthogonal axes: a longitudinal axis (Roll rotation), a vertical axis (Yaw rotation) and a lateral axis (Elevation rotation). The actuation unit actuates the antenna panel so it is maintained aligned with the Earth's equatorial plane and the narrow azimuth beam optionally having a typical width of no more than 2-degree angle eliminates adjacent satellite illumination.
