2020-12-16 (20/05/2021)

A Shom mission took place at Tubuai from 12 to 16 December 2020 (Lagadec, Coubret). During this mission the GNSS receiver Leica GRX1200GG Pro was removed from the station the 2020-12-16. It has been diagnosed broken since 2020-05-26.
Therefore there was no GNSS data logged from 2020-05-26 to 2021-04-20 according to Shom documentation.

GNSS antenna AT504GG has also been removed the same day.


2021-04-20 (20/05/2021)

On the 20th of April 2021, MT Fabien Coubret went to Tubuai and replaced GNSS antenna and receiver with Leica GR25 and Leica AR20.
Leica GR25 comes from SONEL and has been taken from Rangiroa GNSS site. Rangiroa site is under restoration for the moment. E.Poirier
