An Overview of Geomagnetic Field Models

Authors: Robert D. Regan; PHOENIX CORP MCLEAN VA
Abstract:
Over the last decade, the utility of geomagnetic field models or the mathematical representations of the geomagnetic field has expanded considerably, both for civilian and military applications. Such an increase has been accompanied with more interest in models and demands for better accuracies with resultant changes in techniques of model computations and input data requirements. Additionally, such a detailed overview of geomagnetic field models provides a vantage point for reviewing the role of Project MAGNET and provides assessment of the general utility of field models.
