EXAGONE - TERIA is a French company founded in 2005 to provide initially an NRTK service covering all France for the professional surveyors. Current services relevant to GISCAD-OV, are NRTK and PPP-RTK services which cover France and are expanding to Spain, Portugal, Italy, Belgium, Netherlands and Germany.

The company provides only services connected to the high accurate position through GNSS. For that it manages 170 stations, servers in a datacenter and all the infrastructure to enable to ensure a high-quality service. This service provides a centimeter-level accuracy (1-2 cm) in real-time through NRTK and PPP-RTK services available through Internet or by geostationary satellites.

EXAGONE will contribute to the project by calculating, providing and testing the PPP, PPP-RTK (SSR) in NRTK and RTK services. The Company will give access to raw data from some of the owned stations and make tests comparing coordinates with known points. Will also test the possibility to send through Inmarsat the corrections in case the HAS from GALILEO is not available through E6.

In addition, EXAGONE will work on the architecture to provide such a service, as will combine different solutions, like PPP from HAS or GEOFLEX, like SSR from GEO++ and other development that will be necessary for this project
