| Abstract: | The paper presented a calibrating method for error model coefficients of PIGA(pendulous integrating gyro accelerometer) using precision centrifuge with counter-rotating platform,expounded its testing principle and pointed out that it could improve the environmental condition of PIGA test on centrifuge.The test scheme and identification method were given which solved the problem of rotation-related influence caused by centrifuge large arm when implementing high g testing.A data processing method for separating and accurately calibrating error model coefficients were presented,and the problem of sinusoidal inputs caused by counter-rotating platform was solved. |
