Abstract:Aiming at how to test the rate gyro combination automatically and accurately in the environment of high and low temperature,
the method of testing the rate gyro combination was analyzed and a system for testing electrical performance of the rate gyro combination
working in full temperature environmental was proposed. By using Labview modular,a good human-computer interaction interface was
designed and realized;The fast and automatic switching of all the sensitive axes of gyro combination working in the full temperature
environmental can be realized through the three-axis turntable fixed in the temperature chamber,and testing efficiency was improved;The
real-time monitoring and control system was designed,the automatic acquisition of the gyro signal in real-time could be completed and
the test accuracy will be enough. Finally,the accuracy of three-axis turntable in the temperature chamber,the consistency of the test
system were tested and analyzed respectively. The results of the design indicate that the test system has the ability of testing electrical
performance of the rate gyro combination accurately and consistently and gets the advantage of automation and high reliability.
Key words:rate gyro combination;full temperature environment;three-axis turntable;automatic test
