Project objectives


The project EUPOS is a European initiative aiming at establishment of a uniform DGNSS (Differential Global Navigation Satellite System) basis infrastructures in Central and Eastern European countries. Uniform multifunctional DGNSS reference station systems and services will be built up in fourteen participating European countries. It is planned to build up 870 reference stations. The International EUPOS Steering Committee (ISC) and one National Service Centre (NSC) in every participating country will be established linking the different accessing countries and EU member state in an overall project framework.

EUPOS will provide DGNSS correction data for real time positioning and navigation as well as DGNSS observation data for post processing positioning. EUPOS will be able to support precise positioning and navigation with high accuracy - metre, submetre, centimetre in real time and centimetre and subcentimetre in post processing, in another words EUPOS will fulfil all accuracy requirements of geodesy and navigation and will guarantee availability and quality a of service continuity.

In the ever increasing globalisation of economic relationships, Europe needs an infrastructure favourable for positioning and navigation, in order to safeguard and to strengthen the region in the whole and in its economic growth, to develop the social aspects of its cities and regions, to manage and to optimise traffic, for disaster management, security duties and, last but not least, to protect the climate and environment. These constraints demand cost-effective solutions as well as the further development of technical capabilities and mastery of forward-looking technologies.

The technical possibilities offered by the Global Navigation Satellite Systems (GNSS) give the national and state survey departments the chance to fulfil their mission of supplying geodetic reference systems efficiently and largely in accordance to their requirements. The availability of two systems in parallel at the moment, NAVSTAR GPS from the United States of America and GLONASS from the Russian Federation, offers the necessary safeguards, taking into consideration the official statements relating to their continued usability and future development. Finally, these systems will be supplemented by the European development of EGNOS and GALILEO, the first civilian GNSS. As soon as GALILEO will be available, it will be the main standard for EUPOS.

Many European countries have set up DGNSS reference station services since the nineties, providing differential GNSS correction data for real-time positioning or, at least, their observation data for DGNSS post-processing. With its products the state survey administrations provide the fundamental infrastructure for all spatial and land-related information thus supplying an important base for planning and action in the administrative, legal, economic and scientific fields. With the creation in 1989 of the European Terrestrial Reference System (ETRS 89), a three-dimensional geodetic reference system became available for whole Europe for the first time. Its worldwide spatial referencing connection is maintained up-to-date, notably through the EUREF Permanent Network (EPN) which contains the European stations of the International GPS Service for Geodynamics (IGS).

One important task in our days is the protection of mobility of persons and goods. Mobility and economic growth are closely associated to each other. The degree of motorization is increasing further, but the road and railwork networks cannot be extended indefinitely, therefore the traffic flows must be managed and optimised and the limitation of the more avoidable type of traffic is required. By the implementation of transport management systems based on EUPOS the traffic especially at the TINA-corridors will be improved. Simultaneously a multitude of other branches will gain some benefit out of EUPOS. For all these applications reliable and up-to-date information of high quality must always be available online in a technically suitable form. Procedures and techniques must support international standards and improve them, as necessary, in accordance with their respective requirements. Very important also is that DGNSS reference station systems describe the positions three-dimensionally, rather than separating plan position from height data as it is usual in the conventional geodetic networks.

The DGNSS reference station systems already existing in Western Europe are frequently not compatible since the developments were not done cross-border. High-profile experts from the CEE states have seen the historical chance to avoid these difficulties in Eastern Europe. The CEE countries are doing now the first steps to build up GNSS reference stations. The initiative to establish compatible DGNSS reference station systems was started by the over 50 participants from 16 countries of the workshop on "Multifunctional GNSS Reference Station Systems for Europe", 4.-5. March 2002, Berlin, Germany. The International EUPOS  Steering Committee was founded with the aim to draw up in the near future basic concepts concerning setting up multi-functional DGNSS reference station systems compatible with SAPOS® in countries expressing an interest and to outline financing models. The participants wanted to participate on the great experience of SAPOS® in multifunctionality and on the wide application field.

On 21 - 23 November 2003 the 2nd ‘EUPOS® Workshop’ was organised in Berlin by the Berlin Senate Chancellery. The participants of the workshop accepted all statements risen up by the EUPOS® Steering Committee during the conferences in Warsaw, Poland, Sofia, Bulgaria and Riga, Latvia and adopted the resolutions supporting further efforts of the EUPOS® Steering Committee aiming at full realisation of the Project.

The following European countries participate in the Project.

Bosnia and Herzegovina, Bulgaria, Czech Republic, Estonia; Hungary, Macedonia (FYROM), Latvia, Lithuania, Poland, Romania, Russian Federation, Serbia and Montenegro, Slovak Republic and Slovenia and advisory the German states Berlin and Hamburg

It is planned to establish in total up to 870 reference stations in these countries beyond Germany. Since Germany has a complete network of reference stations (SAPOS®) the financial support for this country will be used only for international co-ordination, organisation, supervising and promotion of the Project particularly by the International EUPOS® Steering Committee. Since Slovenia is ready to start building up 8 DGNSS reference stations there is only need for some financial support for the international co-operation in the EUPOS® ISC, training etc.
