Four European Parliament and European Council Resolutions of 10 March 2004 (No. 549/2004 The Framework Regulation, No. 550/2005 The Provision Regulation, No. 551/2004 The Airspace Regulation, and No. 552/2004 The Interoperability Regulation) obliged Member States to implement GNSS (Global Navigation Satellite System). Additional guidelines can be found in Annex 10 to the Convention of International Civil Aviation. In view of the above, a document on the realization of these Resolutions, entitled Local Convergence and Implementation Plan . Poland 2005-2009 has been prepared in our country. Poland treats the issues connected with GNSS implementation with priority which is confirmed by the fact that an ordinance on the issue in question is being prepared by the Minister of Transport (Infrastructure). Since 2002 European Network of Multifunctional Reference GNSS Stations (EUPOS . European Position Determination System) has been developed, and ultimately it is going to have 420 stations deployed in 14 countries. It is assumed that EUPOS will be based on Galileo system standards, but it will also be possible to make use of other available signals, like for example GPS, GLONASS, and EGNOS. Permanent stations are successively deployed within the radius of 70 km. Their coordinates are marked by means of EUREF points, taking into account ETRS 89 and some other conventional geodetic reference systems. Within the framework of the Polish Multifunctional Reference GNSS Stations Network i.e. POLPOS (Polish Position Determination System), which holds a central position of the EUPOS system, it is planned to have 75 stations that in turn should provide three fundamental types of services, mainly EUPOS DGNSS (in real times or post-processing with submeter accuracy), EUPOS RTK (in real time with centimeter accuracy), and EUPOS Geodetic (for accurate geodetic needs). Nowadays, 18 reference stations within the framework of EUPOS operate in our country. Some new ones will be established in the future, including in the State Higher School of Vocational Education in Chelm. Accordingly, new GIS/RTK DGNSS laboratory has been created. The aim of the laboratory is to perform tests on geoinformation software as well as make research on procedures to link this information with the data provided by European Network of Multifunctional Reference GNSS Stations. As a result, it will be used to collect, record, process (perform network and spatial analyses), and make the data available to users by means of the new Polish Multifunctional Reference GNSS Stations Network i.e. POLPOS.
