This year, the Germanophone GNSMART conference organized by TERIA, took place in Paris at the Ordre des Géomètres-Experts (OGE) head office.  On the agenda, 2 days of discussions on this high-tech software with experts.

The first day was exclusively dedicated to the reminder and updating of GNSS standards. The second day was more interactive. The experts covered many topics in order to make the GNSMART software even more optimal. A successful meeting that allowed us to discuss specific themes, “best practices” or to find areas for improvement. 

Among those presents : several GEO+++ members, members of the Dutch land registry, representatives of two private Dutch and Austrian entities, as well as members of the regional and national SAPOS network teams in Germany.

The event ended with a cultural visit to the Arc de Triomphe. The 2019 edition of the GNSMART conference was a real success, the TERIA team thanks the participants for their presence.

What is the GNSMART ?

GNSMART is the first software in the world that offers the ability to provide a service of regional coverage via PPP-RTK (SSR) corrections. The resulting positioning is centimetric in real time.

GNSMART stands for Global Navigation Satellite System – State Monitoring And Representation Technique.

The data transmitted by GNSS technology allows high resolution observations but remains affected by many errors (satellite errors, orbit errors…)

The GNSMART software allows to process these first errors.

It complements this by modelling the general state of the system by addressing regional atmospheric effects (ionospheric and tropospheric effects).

This correction flow is distributed in SSR (State Space Representation) format, ensuring accuracy, reliability and availability, both for real time and post-processing.

From the user’s point of view, no knowledge of the internal structure of the GNSMART system is required. Thanks to the modelling data provided by GNSMART, the user receives observations free of systematic errors. This allows it to determine absolute positions with homogeneous and high accuracy with a single mobile instrument without having to use local proximity stations.
