GnssAntennaDefinition (file format)

Contains a list of GNSS antennas which are identified by its name (type), serial, and radome. Each antenna consists of antenna center offsets (ACO) and antenna center variations (ACV) for different signal types (code and phase). The ACV values for each type are stored in an elevation and azimuth dependent grid.
