Derivation of gravity-related heights from GNSS observations.
Replaces RAC09 model [RGF93 v2 to NGF-IGN78 height (2) (code 8372)]. Accuracy at each grid node is given in the geoid model file. Bilinear interpolation used. For reversible alternative see RGF93 v2b to RGF93 v2b + NGF-IGN78 height (3) (code 10508).
