Branch of US military responsible for maintaining satellite geodesy, conducting geodectic survyes, and collecting, processing, and evaluating gravity data (free-air and Bouguer gravity anomalies).

Software application that does datum transformations. Converts individual positions between over 400 datums to or from user specified TM and UTM grids.

Definitions relating to geodesy, explanations of coordinate systems, and geodesy formulas. Reference ellipsoid defined with derived geometrical constants, equation of the meridional ellipse, and geometry of the meridian section.

Research in geodesy and precision navigation. Advanced researches in 1 cm geoid determination and alternative navigation filters design. Open call for cooperation to all groups with similar interests.

They are part of a research program with the Department of Geological Sciences, Central Washington University.
