Self-Correction of Direct Sensitive Magnetic Compass

摘要

The article gives theoretically a fully discussion of the influence of the magnetic field formed by the iron of the carrier, and a very excellent method so called self-correction to eliminate the influence different from that of tradition. This method is that the magnetic field sensors move around their central axis while keeping the heading course. In this way the magnetic parameters of the carrier can be get and the direct sensitive compass can be rectified.
