2 2 Axis gimbal assembler for direct LOS stabilization of cassegrain antenna and direct LOS stabilization control apparatus

摘要

Provided are a two-axis gimbal assembly for gaze stabilization of a Cassegrain antenna and a direct gaze stabilization control apparatus. A Cassegrain antenna in a curved-surface shape transmits a wireless signal to a target, and receives the wireless signal reflected by the target. The two-axis gimbal is provided with the Cassegrain antenna, and comprises an internal gimbal assembly rotating towards a high angle direction and an external gimbal assembly rotating towards an azimuthal angle direction. A MEMS gyroscope is mounted on the internal gimbal assembly of the two-axis gimbal, thereby measuring an angular speed of the Cassegrain antenna around sensing two axes on an inertial flat surface.
