Aim at the precision limitation for calculating angular velocity because of installation errors of accelerometer in the gyro free strapdown inertial navigation system (GFSINS), a calibration method of installation error parameters is put forward. Based on a six-accelerometer configuration scheme, the calculating method of angular velocity and linear acceleration is analyzed, and the accelerometer...
In the gyro free strapdown inertial navigation system (GFSINS), the precision of system is obviously affected by the static error of accelerometer because accelerometers are used instead of gyroscopes. Firstly, the static error model of accelerometer is built, and the effect of static error for angular velocity calculation in a nine-accelerometer configuration system is given. Then, the accelerometer...
