Research on Micro Inertial Sensor Error Compensation Technology in SINS

Abstract:

The micro inertial sensor parts (gyroscope and accelerometer) measurement error is the main factors to influence the accuracy of the inertial navigation system, in order to improve the navigation precision of SINS (strap-down inertial navigation system), we must reduce inertial sensor measurement error. Based on the error analysis of the inertial measurement device, with accelerometer attitude computation information as gyro attitude computation information reference quantity, established the algorithm of the attitude angle. In the sensor output signal pretreatment technology, this paper mainly introduced the use of surface fitting technology, to establish the error compensation surface equation, and gives the mathematical derivation of calculation error model parameter, the experiment got a good compensation effect.
