Abstract
A vehicle navigation system includes an external source sensor onboard a vehicle system that determines headings of the vehicle system. The external source sensor determines the headings using signals received from an off-board, external system. The navigation system also includes a magnetic sensor onboard the vehicle system that measures magnetic fields along different axes at different times. One or more processors determine a combination of the magnetic fields, determine a position translation and/or a magnitude scaling of the combination of the magnetic fields, and modify at least one of the headings based on the position translation and/or the magnitude scaling.
