1. A method for generating a magnetic heading for a mobile terminal, comprising:
- determining a geographic position of the mobile terminal;
sensing a magnetic field at the mobile terminal;
determining a magnetic inclination and/or a magnetic declination of the magnetic field based on the determined geographic position; and
determining a magnetic heading for the mobile terminal based on the sensed magnetic field and based on the determined magnetic inclination and/or magnetic declination.

Abstract
Mobile terminals, methods, and program products for generating a magnetic heading. A geographic position of the mobile terminal is determined. A magnetic field at the mobile terminal is sensed. A magnetic inclination and/or a magnetic declination of the magnetic field is determined based on the determined geographic position. A magnetic heading is determined for the mobile terminal based on the sensed magnetic field and based on the determined magnetic inclination and/or magnetic declination.
