INFORMATIVENESS OF VECTOR MAGNETOMETER MEASUREMENTS AND GLOBAL GEOMAGNETIC FIELD MODELS IN THE AIRCRAFT INS AIDING

摘要

Recent global geomagnetic field models provide high-resolution information about the anomalous magnetic field. The paper aims to investigate the global model data informativeness for the aircraft navigation using a strapdown inertial navigation system and a three-axis fluxgate magnetometer. We consider the strapdown INS aiding based on in-flight magnetometer measurements and the global model data. Standard Kalman filtering technique is applied. Simulation results obtained using the global model EMM2015 are discussed.
