Characteristic testing technology of three-axis diagonal integration of fiber-optic gyro is an important part of high precision intertial navigation. The original calibration method of the scale fator and resolution of threeaxis diagonal integration of fiber-optic gyro depends on the tooling and tests the gyro one by one based on the theoretical testing model. The testing time of original method is long and the method is strict in precision of tooling. Aiming at the above problems

put forward a new method that calibrates the scale factor and resolution by measuring installation error and calculating rotation matirx. The experiment proves that the new method can calibrates the scale factor and resolution of all gyro of three-axis diagonal integration of fiber-optic gyro quickly and accurately. The new method has solved the problems of original testing technology for three-axis diagonal integration of fiber-optic gyro being complicated

time-consuming

strict in clamping.
