Paper Abstract

The electro-optical tracking system with the capability of target capture and tracking, is typical astronomical observation instruments. In most of the task scenarios, the electro-optical tracking system must finish the azimuth zero calibration at the initial stage. Two methods are usually used for zero calibration: (1) with the aid of the external autonomous north seeking equipment; (2) with the help of the astronomical measurements under clear weather. The former problem is the increased cost for purchasing additional equipment and training operators, while the latter is limited by weather conditions and personnel experience. In this paper, an independent azimuth zero calibration method based on single gyro for electro-optical tracking system is proposed, which introduces a four-position method on the basis of high-precision angle measure sensor and gyro equipped in the system to calibrate azimuth zero point. The all-weather independent azimuth zero calibration is realized, after data sampling and processing. The experimental verification results illustrate the azimuth zero calibration precision is less than 3’ in 4 minutes, meeting the initial zero calibration requirements of electro-optical tracking system.
