Abstract
Stabilization and automatic pointing and tracking platform (PTP) is an important field among the applications of the inertial technology. And because of its broad application foreground, antenna stabilization has e a hotspot of stabilization and automatic PTP. The core of stabilization platform is the attitude measurement and control of the carrier. The main of this article according to the camera steady platform system structure and project design based on the micro-gyroscope.
With whole stabilization ability, whole airspace tracking and no blind-zone, a high accuracy three-axis E-O stabilization and Tacking Devices (EOSTD) which uses a MEMS velocity gyroscope as inertia1 ponent was introduced. The stabilization model were deduced based on the cape speed theory. Three-axis EOSTD could restrain the image rotation around the LOS axis to reach a high stabilization carries on the camera steady platform system structure and the project design, obtains the DSP hardware circuit module. Then make the point of antenna unchangeable by using stated control mould. The error pensated through adopting the calculate way of dynamic state error pensate to realize the exaltation of this system measure accuracy. This system has been developed many experiments, the result has been proved to be better and better.
This paper firstly introduces the origin of the project, research significance, related technical status and main resea
