Progress in antenna calibrations — Recommendations R. Schmid, G. Wübbena, G. Mader, B. Haines

Recommendations (1)‏ future reprocessing campaigns should use an updated antenna model z-offset values for newly launched satellites are estimated from the weekly SINEX solutions; only those ACs can be considered that have satellite antenna offset corrections included; consistency with the existing values has to be guaranteed the JPL antenna maps should somehow be merged with the IGS model; ACs are encouraged to estimate azimuth- dependent satellite antenna PCVs

Recommendations (2)‏ allow the use of individual calibrations within the IGS network? request robot calibrations for new ground antenna types

Open issues how to add GLONASS calibrations (frequency division multiple access!) to ANTEX files? how to add (receiver-dependent!) carrier-to-noise patterns CN0 to ANTEX files? how to get a general definition for the orientation of receiver antennas to North? rules for the update of the various antenna files? group delay variations for ground and satellite antennas?
