Magnetic Heading Reference
US Patent:
3943763, Mar 16, 1976
Filed:
Dec 11, 1974
Appl. No.:
5/531647
Inventors:
Howell D. Garner - Newport News VA
Assignee:
The United States of America as represented by the United States

International Classification:
G01C 2100
US Classification:
73178R
Abstract:
This invention employs a magnetometer as a magnetic heading reference for a vehicle such as a small aircraft. The magnetometer is mounted on a directional dial in the aircraft in the vicinity of the pilot such that it is free to turn with the dial about the yaw axis of the aircraft. The invention includes a circuit for generating a signal proportional to the northerly turning error produced in the magnetometer due to the vertical component of the earth's magnetic field. This generated signal is then subtracted from the output of the magnetometer to compensate for the northerly turning error.
