A REPRAA é a Rede Estações Permanentes da Região Autónoma dos Açores. Tem estações espalhadas pelos três grupos e providencia dados GNSS para pós-processamento e serviços de dados em tempo real.

Network of Permanent GNSS Stations in Greece operated by the Research Institute of Geodesy, Topography and Cartography, Geodetic Observatory Pecny and the Charles University in Prague, Faculty of Mathematics and Physics, Department of Geophysics, in close cooperation with the Seismological Laboratory of University of Patras

Research and experimental network of permanent GNSS stations operated by the Research Institute of Geodesy, Topography and Cartography, Geodetic Observatory Pecny in cooperation with more academic and research institutions in the Czech Republic: Brno University of Technology, Palacky University of Olomouc, Technical University of Ostrava, West-Bohemia University in Pilsen, Institute for atmospehric physics CAS, Military Geography and Hydrometeorologic Office Dobruska.

Orbits of GNSS satellites and Earth rotation parameters based on analysis of GNSS observations from a global network of IGS (International GNSS Service) stations in rapid or ultra-rapid processing mode.

Time series of tropospheric parameters by analysing of GNSS observations from a global IGS (International GNSS Service) network and regional networks - EPN (EUREF Permanent Network) in Europe and VESOG, GEONAS and CZEPOS in Czech Republic.

Coordinate time series based on analysing GNSS observations from a subset of EPN (EUREF Permanent Network) or CZECH - GNSS networks in Czech Republic - VESOG, GEONAS, CZEPOS. It includes daily solutions from EUREF processing or EUREF reanalyses.

A Rede Nacional de Estações Permanentes GNSS (ReNEP) é a infraestrutura de estações permanentes GNSS que contribui para a definição do Referencial Geodésico Nacional. Atualmente conta com 47 estações em todo o território Nacional, os dados são geridos e difundidos pela Direção-Geral do Território, sendo fornecidos gratuitamente em formatos standard.
