The stabilization accuracy is crucial to the gun control system of tank.According to the shortages of current measuring ways of stabilization accuracy

a measuring method for stabilization accuracy of tank gun control system using gyroscope as sensor is put forward firstly.The gyroscope gathers angle signals of the gun

and the signals are transmitted to data acquisition circuit

data is stored in electrical disk.The gun vibrating curve can be drawn on screen of test instrument

and stabilization accuracy is gotten.Moreover the measuring data can be transferred to computer for further processing.Compare the measurement values gotten from testing equipment with quadrant readings

the errors are below 1.5%

so the testing instrument is effective for testing stabilization accuracy.
