GPS has become the pervasive means for positioning and timing. Alpha
GPS & Geodesy offers courses on the mathematical and geodetic
foundation of GPS, or more generally GNSS (Global Navigation
Satellite Systems). The depth of the material presented and its
mathematical rigor lead to a detailed understanding of all levels of
positioning accuracy, ranging from 100 meter cursory positioning to
millimeter high accuracy applications. These undergraduate and
graduate level online courses are available for
credit and non-credit.
