New-type gimbal mount of airborne optoelectronic platform and its key technologies

The foreign new-type gimbal mount of airborne optoelectronic platform and its key technologies were reviewed. Combined with the development trend of equipment products of airborne optoelectronic system, the technical status of gimbal mount platform was described, and the configuration, vibration isolation form and stability accuracy were introduced. From the aspects of task integration, high-precision stability and motion compensation, the requirements of airborne optoelectronic system on gimbal mount platform, such as larger space for task sensor layout, stronger motion compensation function and higher stability of ring frame were analyzed. The foreign new-type unconstrained driving-active following and parallel-type active following gimbal mount platform innovative technologies were researched. The results show that the foreign new-type gimbal mount of airborne optoelectronic platform realizes the stability performance of 3 axis over 5 μrad on the basis of mission load and gimbal mount mass ratio greater than 1. Finally, the key supported technologies of new-type gimbal mount of airborne optoelectronic platform were proposed.
