Magnetic navigation using measurements of the Earth's crustal magnetic field variation is a promising new approach for use by aircraft flying in a GPS-denied environment. The magnetic signature of the crust cannot be masked or jammed. We propose to develop a magnetic field reference sensor ideally suited for magnetic navigation: it must measure the total magnetic field with high sensitivity and accuracy in all orientations. All commercial total field magnetometers have a dead axis or a dead plane. A second goal is to develop a low-cost and easily manufacturable sensor package.  In Phase I we propose to build and demonstrate the core sensor performance in preparation for further development in Phase II. At the end of a Phase II program we plan to have rugged and reliable prototype sensors available for testing and use.
