Abstract
Control systems and methods are provided for improved azimuthal pointing control near gimbal zenith/nadir in two-axis gimbal systems mounted to moveable platforms. The system includes a two-axis gimbal and a two-axis pointing device mounted to the two-axis gimbal. The two-axis pointing device directs a line of sight axis based upon a commanded steering direction and movement of the platform in the inertial frame of the line of sight. The two-axis gimbal follows the movement of the two-axis pointing device, keeping the two-axis pointing device from encountering its mechanical limits. In this manner, inertial pointing control is maintained in the near gimbal zenith/nadir regime.
