Design and Realization of the Calibration Equipment for Inertial Navigation System by the Control Computer

Abstract:

Aiming at the problem of calibrating the INS in non-laboratory conditions, this thesis proposes the calibration methods by as the core and combined use of double-position directional gyro calibration, four-position horizontal gyro calibration and Schuler circuit accelerometer calibration etc. It builds up the model for scale factor calibrating, controls the inertial platform by the embedded control technique to make it the three-axis turntable state, and uses the Linux OS and C language design control software to design and develop the automatic calibration equipment for the INS. This equipment is simple in operation, easy in use and portable, and therefore can realize automatic calibration in non-laboratory conditions. And the results meet the requirements for guarantee the precision of the system in use.
