  1. Advanced Aeromagnetic Compensation Models for Airborne Magnetic Anomaly Navigation

    Gnadt, Albert ReubenMassachusetts Institute of Technology2022

    Using the earth's magnetic anomaly field for navigation of aircraft has shown promise as a viable alternative to the Global Positioning System (GPS) and other navigation systems. An airborne magnetic anomaly navigation (MagNav) system collects real-time magnetic field data and uses predetermined …
