Summary
Precise GNSS positioning requires the calibration of the receiving antennas. Antenna field calibrations, in contrast to lab calibrations, use the signals transmitted by GNSS satellites. With the present transition to additional GNSS and new frequencies we encounter the problem that field calibrations have to be performed with incomplete satellite constellations. Based on test calibrations we are able to demonstrate that this obstacle can be overcome by the extension of the calibration duration.
