PreprocessingVariationalEquationSstFit

This program fits two inputfileVariational1/2 to satellite-to-satellite-tracking (SST) and orbit observations in a GRACE like configuration. It works similar to PreprocessingVariationalEquationOrbitFit, see there for details.

As the relative weighting of the observation types is important complex description of the covariances can be set with covarianceSst, covariancePod1, covariancePod2.
