Simulated Maritime Magnetic Navigation in the Asia-Pacific Region
This paper investigates the potential use of the Earth’s magnetic field as a source of position information to correct an inertial navigation system (INS) estimated position of a maritime vessel. A simplified two-dimensional INS is considered using measurement information from either scalar or vector measurements of the Earth’s magnetic field. The measurement update is developed from existing global magnetic field models in the regions of interest. Cramer-Rao lower bound (CRLB) analysis is performed for this simplified system for two common marine vessel operating modes, transit between ports and localized operations.
