Abstract

The present application provides a turntable calibration method and device. The method includes: acquiring the first acquisition parameter corresponding to the parameter to be measured collected by the inertial navigation system installed on the turntable; acquiring the second acquisition parameter corresponding to the parameter to be measured output by the turntable Parameters: performing a calibration test on the turntable according to the first acquisition parameter and the second acquisition parameter corresponding to the parameter to be measured. This solution uses the inertial navigation system to test and calibrate the turntable, which simplifies the procedure of the turntable calibration, and at the same time realizes the intelligence and automation of comprehensive testing, reduces the participation of test personnel, and improves efficiency.

Description

technical field [0001] The present application relates to the technical field of testing, in particular to a method and device for calibration of a turntable. Background technique [0002] The turntable is a special measuring device used to calibrate the attitude angle position, angular rate and dynamic characteristics of inertial devices. It can provide typical motion simulation of ships, aircrafts and other carriers. It is an indispensable test equipment for inertial testing. One, with functions such as position, speed, swing, and servo, can meet the test and experiment of shipboard, vehicle, and airborne inertial systems and inertial components. Since the turntable is an important instrument for testing, verifying and calibrating inertial navigation devices and guidance systems, its performance directly affects the accuracy of the inertial navigation system. Therefore, it is more and more important to strengthen the research on the calibration technology of the turntable...
