A high performance inertial system that includes magnetometers can provide accurate platform heading information in a variety of applications and operational environments. However, performance depends greatly on where the inertial system is installed within the application, as magnetometers are susceptible to measurement distortion in the presence of any magnetic material.

The paper puts forward recommended integration guidelines for inertial systems, including:

  • Sources of both hard and soft magnetic field distortion
  • Mounting hardware used for inertial systems
  • The use of shielding
  • Platform considerations.

Following a discussion on the evaluation of magnetic disturbances, the paper goes on to address how to compensate for magnetic disturbances, covering Compensation Procedures, Factory Calibration and Operational Compensation Considerations.
