1. A method for magnetic data compensation comprising:

  • providing at least one magnetometer mounted on a subsea vehicle;

    maneuvering the subsea vehicle at a first altitude above the seafloor and a first heading;

    receiving, by a microprocessor, a first set of raw output from the magnetometer;

    receiving, by a microprocessor, subsea vehicle state data and subsea vehicle performance data concurrently with the receiving of the first set of raw magnetic data; and

    processing, by a microprocessor, the subsea vehicle state data, the subsea vehicle performance data, and the first set of raw magnetic data to produce magnetic compensation coefficients.
