Intervention by the SHOM and IGN to change the mast support of the GNSS antenna. Now, the support is in stainless steel.

2020-12-17 (17/12/2020)

There has been a SHOM mission on Is. Royale from 7th to 11th of December 2020. Since the 11th, various test have been done on the GNSS config but the router is down and no GNSS nor TG high frequency data are sent for the moment.

2020-12-11 (11/12/2020)

There was a problem in the processing of the GNSS data by IGN. This will be solved shortly. Since the 17th of October 2020, date of receiver replacement, the data have been correctly sent by the receiver to IGS server. Nothing has been lost. E.Poirier

2020-10-17 (04/11/2020)

2020-10-17/ 10:45Z GNSS receiver Trimble netr9 removed.
2020-10-17/ 11:20Z GNSS receiver Trimble Alloy installed.
However the data cannot be sent for the moment. There is still network issues.
