GEODYN is used extensively for satellite orbit determination, geodetic parameter estimation, tracking instrument calibration, satellite orbit prediction, as well as for many other items relating to applied research in satellite geodesy using virtually all types of satellite tracking data.

The GSFC time variable gravity mascon products optimize the signal-to-noise ratio through the application of spatial regularization in the estimation of both monthly and high-resolution trends from GRACE and GRACE-FO Level 1B data. These mascon products do not require any additional filtering prior to their research application.

The NASA-USDA Global soil moisture data provides soil moisture information across the globe at 0.25°x0.25°spatial resolution.

Satellite laser ranging (SLR) tracking data provides more than four decades of measurements useful for estimating the long wavelength components of time-variable gravity, including C20 and C30. The estimation of these gravity coefficients with SLR has been critical to the success of the GRACE and GRACE-FO missions. GSFC routinely provides estimates of the gravity coefficients up to degree and order 5.
