Description
Global Navigation Satellite Systems (GNSS) can typically not contribute to the scale of the terrestrial reference frame because the satellite antenna offsets are not known to the scientific community. With the disclosure of the values for the Galileo IOV satellites a first system provider has published such data allowing to overcome this deficiency in future. In order to make the full benefit of the information also calibrations for the Galileo E1 and E5 frequencies for the ground receiver antennas are required.
We present results from a dedicated study on the use of the recently published satellite antenna calibration values where their influence on the coordinates of the ground tracking stations is estimated. Within the EUREF Permanent Network, for a limited number of stations receiver antenna pattern from a chamber calibration are available where also values for the Galileo E1 and E5 signals are included. This allows at least a limited evaluation to which extent these alternative calibration values are compatible to those traditionally used by the IGS/EPN.
