Problems solved by technology

This method is suitable for stable platforms under the condition of general stable accuracy, but for high-precision stable platforms, there is a non-negligible installation error, which affects the stable accuracy of the stable platform; the gyro velocity information of the stable platform participates in the calculation of the geographic coordinates of the ground target, and the installation error affects the solution. When the stable platform is used for too long or the support surface of the gyroscope is deformed due to collision, this calibration method has the advantages of fast, convenient and accurate

Abstract

The invention provides a calibration system for a gyroscope installation error, and a calibration method thereof. The calibration system comprises an error calibration platform, an error calibration rigid body rotation table, a data transmission device and an error calibration upper computer, wherein the error calibration platform rotates and drives the error calibration rigid body rotation tableto rotate at an even speed after the error calibration platform is electrified; the error calibration rigid body rotation table drives an error calibration gyroscope to rotate; the speed information of the error calibration gyroscope is transmitted to the error calibration upper computer through the data transmission device; the error calibration upper computer displays the installation error angle value of the error calibration gyroscope according to the speed information; and according to the installation error angle value, the installation error of the error calibration gyroscope is calibrated so as to realize quick and accurate compensation.

Description

technical field [0001] The invention relates to the technical field of servo control systems, in particular to a gyroscope installation error calibration system and a calibration method thereof. Background technique [0002] With the continuous improvement of the demand for precise reconnaissance targets, the application of light and small reconnaissance stable platforms with tracking and guidance functions is becoming more and more extensive. Compared with the traditional reconnaissance platform, the light and small platform not only has the characteristics of flexible and flexible use, but also can provide short-distance ground information quickly and accurately. Due to the small platform (short for light and small stable platform) structure frame and gyroscope installation position, there are installation errors. When the small platform adopts the semi-strapdown servo control method, the installation error participates in the attitude calculation of the azimuth and pitch ...
