Abstract
An antenna system for a satellite including a gimbal device, such as a bi-axial gimbal, that employs a first uni-axial gimbal providing movement in one direction and a second uni-axial gimbal providing movement in a perpendicular direction. The first gimbal is mounted to a platform bracket, which is part of a moveable platform. The first gimbal is also mounted to the second gimbal, and the second gimbal is mounted to a satellite bracket secured to the satellite. Both a receive antenna array and a transmit antenna array are mounted to the moveable platform. Therefore, movement of the first gimbal causes the combination of the receive and transmit antenna arrays to move in one direction, and movement of the second gimbal causes the combination of the receive and transmit antenna arrays to move in the perpendicular direction.
