Ladies and Gentlemen
Because the EPN Central Bureau (EUREF)
cannot accept
TRM55971.00 SCIT
(Trimble 55971.00 antenna together with SCIT
Radome)
without true absolute calibration values,
the colleagues in the Hvratska Geodetski Institut /
Croatian Geodetic Institute removed the
SCIT Radome in the DUBR GPS+GLONASS
Permanent Tracking Station Dubrovnik, Croatia,
2007-06-19T18:00Z.
With best regards
Rudi
