[IGSSTATION-7928] - 2020-04-08 (14/04/2020)

the firmware of WGTN (Wellington, New Zealand) Trimble Alloy receiver has been upgraded to release 5.43 on 2020-04-07 23:29 UTC.

An updated site log has been submitted to IGS CB.

[IGSSTATION-7885] - 2020-02-19 (18/03/2020)

on 2020-02-14T01:16Z the receiver and antenna at WGTN (Wellington, New Zealand) have been upgraded to the following models.

Antenna Type : TRM115000.00 NONE
Serial Number : 1551016811

Receiver Type : TRIMBLE ALLOY
Serial Number : 5921R40132

An updated sitelog has been submitted to IGS.

[IGSSTATION-7390] - 2018-08-03 (03/08/2018)

the Trimble NetR9 receiver at WGTN (Wellington, New Zealand) has been replaced today due to faulty internal batteries.

Due to this fault, data from 212/2018 (06 UTC) to 214/2018 (22 UTC) have been permanently lost.

Data logging and real time streaming are now restored.

[IGSSTATION-7354] - 2018-07-05 (12/07/2018)

We have recently found that the WGTN sitelog was missing one entry for WGTN (Wellington, New Zealand).

In detail, the ASHTECH Z-XII3, sn LP00155 receiver, had the firmware version “1E95” installed from 1996-08-19T22:13:01Z to 1999-06-13T16:42:58Z.

This has now been fixed, and a new version of the sitelog has been submitted and approved through the IGS Site Log Manager.

Rinex headers were already correct, so there is no need to resubmit these data.

[IGSSTATION-6067] - 2015-01-12 (12/01/2015)

Thanks to my GNS Science colleague Neville Palmer, we realized that we had a wrong record for the antenna installed at the IGS site WGTN (Wellington, New Zealand) in our database.

The time period affected runs from 1996-05-23 to 2005-03-21.

Unfortunately, this error was reflected in the IGS logfile , and in the header of all Rinex files uploaded to CDDIS and IGN during the above time period.

The antenna was wrongly recorded as ASH700936C_M .

The correct code to be considered is instead: ASH700936B_M

An updated version of the site log (4.1 and 4.2 fields) has been submitted and approved by IGS Central Bureau.
