| Abstract: | In this paper, a new method of calibrating the strapdown inertial measurement unit (SIMU) of middle and low accuracy without opening the box is studied and a suit of six-position scheme is provided. By this method a SIMU of low accuracy can be calibrated. It uses a high accuracy SIMU instead of needing a high-precision testing turntable. Theoretical analysis shows that it is effective in separating the errors of gyro and accelerometers via least squares estimation. |
