GNSS Absolute Antenna Calibration

The robot-based antenna calibration service provide absolute calibration of GNSS ground and satellite antenna for the complete 0–90° elevation and 0–360° azimuth range and is the IGS-recommended calibration method.

The phase centre of a GNSS receiving antenna is not a single exact point; rather does it vary in accordance with the direction of the received signal. These phase centre variations (PCV) are function of elevation and azimuth are determined and provided as PCV corrections.

Access to GNPCVDB

GNPCVDB is a webservice allowing the access to phase center offsets and variations (PCV) type corrections of GNSS antenna calibrated by the Automated Absolute Field Calibration.
