摘要：
This paper introduces a new method for small diameter directional gyro inclinometer calibration with continuous measurement mode. The mathematical models referring to the relationship between the input and output of the accelerometers and the gyro are established. Experiment has been conducted for different angular speed and different positions on a three-axis turntable. We totally obtained 36 groups of experiment data of different angular speed regarding to different positions. Through the application of the established mathematical models and by means of computer aided data procession, the scale factors, installation error and static drift for the gyro inclinometer are calculated. Thus, the inclinometer calibration is implemented. It has been verified that this new calibration method enables us to quickly and effectively calibrate gyro inclinometer. The established mathematical model has been proved to be exact and effective. The whole operation is simple, quick and reliable.
