Abstract

Magnetometers-aided MINS could solve roll angle measurement of air vehicle at fast spinning rate, but magnetometers were easily disturbed and had measuring error, so it was necessary to establish tri-axial magnetometer correction system for magnetometers-aided MINS navigation system. Based on LabWindows/CVI and MATLAB fuzzy programming, earth magnetic field and ellipsoid fitting model were built to complete magnetometers correction system and its virtual instrument. On that basic, magnetometers-aided MINS navigation system and its virtual instrument were established. Results of correction and non-correction magnetometers-aided MINS navigation test showed that the magnetometers correction system can compensate the error of interference, measuring and so on, furthermore geomagnetic attitude computing become more accurate and the higher precision of position and velocity for magnetometers-aided MINS system. All of them are significant for engineering and products.
