APPARAT UND METHODE ZUR BESTIMMUNG VON AZIMUT, NEIGUNG UND ROLLEN.

摘要

Apparatus and method for determining the azimuth (heading), pitch and roll which include a magnetometer-type sensor providing Hx, Hy and Hz related signals, and coil elements wound around the magnetometer which selectively impose specific magnetic fields about the sensor. The Hx, Hy and Hz field components of the magnetic field are measured from the sensor with and without the selective energization of the magnetic coils and stored, from which the azimuth, pitch and roll are calculated. Furthermore, quadrant correction is applied such that a unique reading is produced for all angles through 360 DEG of azimuth, pitch or roll.
