Abstract

When environmental magnetic field is not uniform or background magnetic field is much bigger, the classical method using optical pump and fluxgate arise error. For this problem, by analyzing the classical method, the relationship between maneuver angles and direction cosines was derived, and a new method using optical pump and GPS was studied. The new method uses GPS to get direction cosines as it is not influenced by magnetic interference. The experimental result shows that the method has good effect on compensation.

Key words： aeromagnetic survey; aircraft background magnetic field; direction cosines; GPS
