Première station installée à Saint-Barthélémy

TERIA is the first network to set up a station in Saint-Barthélémy.

The installation of a GNSS station on the island of Saint-Barthélémy was one of TERIA’s key prospects for 2019. Promise made. On June 5, TERIA installed the first station on the roof of the Meteo Centre building in Gustavia.

The objective of the TERIA network is to offer users a service of general interest by offering “a real-time GNSS localization service with centimetric accuracy”. Here is how the project is mentioned in the agreement known as the temporary occupation of the public domain constituting real rights drafted by the community of Saint Barthélémy.

Last January, a member of TERIA’s technical department made a first survey visit to prepare the installation file. It was also an opportunity to meet the representative of the overseas territorial community of Saint Barthélémy, Mr Bruno MAGRAS. This first contact was made possible thanks to the National Geographic Institute (IGN),  an unconditional partner. Indeed, from the outset, a unique public/private partnership between TERIA and IGN was planned. It guarantees the labelling of the data necessary for the technical operation of the network. In return, this agreement provides that data from TERIA stations will be available on the RGP website. This partnership has been renewed very recently (read the article : Partnership renewal IGN – EXAGONE).

As a reminder, the TERIA network has more than 200 stations spread over the entire national territory, thus forming the largest quantitative network of the permanent GNSS network (RGP), which currently has 526 stations.

A station 100% operational

The installation site was submitted by the community that proposed the roof of the building of the Saint Barthélémy meteorological centre. This proposal has thus accelerated the signing of the agreement. Six months later, the first TERIA station appeared. After only three days, the observations and analyses of our experts showed that the GNSS station was stable and therefore 100% operational.

To make the station officially active, the IGN carries out an observation period, which is essential to attest to the quality and reliability of the station’s data. Generally, this period lasts 3 weeks. After validation of the IGN, the station is listed in the form of a “station sheet”.  This identity sheet contains the station’s contact details, equipment, site and data quality and time series.

Today, the Saint-Barthélémy GNSS station appears under the name : GSTV (available on the IGN website).
