The Trimble NetRi firmware at AUCK, CHTI and DUND (New Zealand) has been upgraded to version 5.22.

Updated sitelogs have been submitted to IGS.

Due to the change in the Rinex3 name introduced by this firmware, the provision of Rinex3 data to IGS will be interrupted until the firmware upgrade is rolled out on all the IGS sites we operate.
