etween 13 study groups. By <str<strong>on</strong>g>the</str<strong>on</strong>g> establishment <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> CEGRN C<strong>on</strong>sortium, an organizati<strong>on</strong> thatc<strong>on</strong>forms to <str<strong>on</strong>g>the</str<strong>on</strong>g> European research policy trends, <str<strong>on</strong>g>the</str<strong>on</strong>g> participating countries would like to ensure<str<strong>on</strong>g>the</str<strong>on</strong>g> l<strong>on</strong>g-term c<strong>on</strong>tinuati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> project. The CERGOP-2 project was funded within <str<strong>on</strong>g>the</str<strong>on</strong>g> EU’sfifth Framework Programme.323. C<strong>on</strong>siderable experience is gained with differential GNSS service in many countries <str<strong>on</strong>g>of</str<strong>on</strong>g><str<strong>on</strong>g>the</str<strong>on</strong>g> regi<strong>on</strong>. Differential methods are used, e.g., in <str<strong>on</strong>g>the</str<strong>on</strong>g> Czech Republic where <str<strong>on</strong>g>the</str<strong>on</strong>g> TechnicalUniversity operates a reference stati<strong>on</strong> in Prague. The correcti<strong>on</strong>s are transmitted to <str<strong>on</strong>g>the</str<strong>on</strong>g> rovingreceivers via FM and l<strong>on</strong>g-wave radio. It is known that advanced nati<strong>on</strong>al and regi<strong>on</strong>al DGNSS<strong>systems</strong> would significantly improve <str<strong>on</strong>g>the</str<strong>on</strong>g> positi<strong>on</strong>ing accuracy and boost <str<strong>on</strong>g>the</str<strong>on</strong>g> applicati<strong>on</strong>s. To thisend, <str<strong>on</strong>g>the</str<strong>on</strong>g> establishment <str<strong>on</strong>g>of</str<strong>on</strong>g> a multi-purpose GNSS reference network (EUPOS, European Positi<strong>on</strong>Determinati<strong>on</strong> System) is currently under c<strong>on</strong>siderati<strong>on</strong> by an internati<strong>on</strong>al working group <str<strong>on</strong>g>of</str<strong>on</strong>g>experts. The network would adopt <str<strong>on</strong>g>the</str<strong>on</strong>g> standards successfully developed in Germany for <str<strong>on</strong>g>the</str<strong>on</strong>g>irSAPOS (Satellite Positi<strong>on</strong>ing Service) system.324. In many countries, <str<strong>on</strong>g>the</str<strong>on</strong>g>re is a need to increase <str<strong>on</strong>g>the</str<strong>on</strong>g> awareness <str<strong>on</strong>g>of</str<strong>on</strong>g> policy makers <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g>benefits <str<strong>on</strong>g>of</str<strong>on</strong>g> GNSS, and at <str<strong>on</strong>g>the</str<strong>on</strong>g> same time, to increase funding available to establish a nati<strong>on</strong>alinfrastructure. Fur<str<strong>on</strong>g>the</str<strong>on</strong>g>rmore, <str<strong>on</strong>g>the</str<strong>on</strong>g> proper governmental organizati<strong>on</strong>al structure to deal with GNSSissues needs to be established, which is sometimes difficult due to <str<strong>on</strong>g>the</str<strong>on</strong>g> multi-disciplinary nature <str<strong>on</strong>g>of</str<strong>on</strong>g>GNNS issues. In Austria, as a good example, <strong>satellite</strong> navigati<strong>on</strong> activities are co-ordinated andmanaged by <str<strong>on</strong>g>the</str<strong>on</strong>g> GALILEO C<strong>on</strong>tact Point Austria (www.galileo-austria.at) established at <str<strong>on</strong>g>the</str<strong>on</strong>g>Austrian Space Agency (ASA, www.asaspace.at), and by <str<strong>on</strong>g>the</str<strong>on</strong>g> Austrian Institute <str<strong>on</strong>g>of</str<strong>on</strong>g> Navigati<strong>on</strong>(OVN, www.ovn.at). A nati<strong>on</strong>al testbed – <str<strong>on</strong>g>the</str<strong>on</strong>g> Austrian Radi<strong>on</strong>avigati<strong>on</strong> Technology andIntegrated Satnav services and products Testbed (ARTIST) - has been established by <str<strong>on</strong>g>the</str<strong>on</strong>g> FederalMinistry <str<strong>on</strong>g>of</str<strong>on</strong>g> Transport, Innovati<strong>on</strong> and Technology (BMVIT) in order to dem<strong>on</strong>strate throughpilot projects <str<strong>on</strong>g>the</str<strong>on</strong>g> value <str<strong>on</strong>g>of</str<strong>on</strong>g> navigati<strong>on</strong> services <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> European GALILEO <strong>satellite</strong> system to beoperati<strong>on</strong>al by 2008. Through <str<strong>on</strong>g>the</str<strong>on</strong>g> ARTIST Programme, various applicati<strong>on</strong> areas will bedem<strong>on</strong>strated and evaluated with respect to <str<strong>on</strong>g>the</str<strong>on</strong>g>ir innovative character and pr<str<strong>on</strong>g>of</str<strong>on</strong>g>itability. Inparticular, <str<strong>on</strong>g>the</str<strong>on</strong>g> objectives <str<strong>on</strong>g>of</str<strong>on</strong>g> ARTIST are to test and establish new and promising market segmentsfor <strong>satellite</strong> navigati<strong>on</strong> applicati<strong>on</strong>s, to increase <str<strong>on</strong>g>the</str<strong>on</strong>g> awareness <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> capabilities <str<strong>on</strong>g>of</str<strong>on</strong>g> <strong>satellite</strong>navigati<strong>on</strong> applicati<strong>on</strong>s in general, and to stimulate Austrian instituti<strong>on</strong>s to increasinglyparticipate in <str<strong>on</strong>g>the</str<strong>on</strong>g> internati<strong>on</strong>al navigati<strong>on</strong> applicati<strong>on</strong>s networks. All Austrian instituti<strong>on</strong>s relatedto navigati<strong>on</strong> and its applicati<strong>on</strong>s are encouraged to participate in <str<strong>on</strong>g>the</str<strong>on</strong>g> ARTIST Programme.325. The main topics <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> first “Call for Proposals” opened in April 2002, funded by <str<strong>on</strong>g>the</str<strong>on</strong>g>BMVIT with an amount <str<strong>on</strong>g>of</str<strong>on</strong>g> € 2.000.000. Topics comprised: fleet management, including allmodalities and inter-modalities, agriculture and forestry. The large number <str<strong>on</strong>g>of</str<strong>on</strong>g> project proposalsreceived (22) was an impressive resp<strong>on</strong>se to <str<strong>on</strong>g>the</str<strong>on</strong>g> efforts <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> BMVIT to support and streng<str<strong>on</strong>g>the</str<strong>on</strong>g>n<str<strong>on</strong>g>the</str<strong>on</strong>g> navigati<strong>on</strong> market in Austria. The durati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> projects shall be approximately <strong>on</strong>e year.Thus, it will be possible to evaluate <str<strong>on</strong>g>the</str<strong>on</strong>g> project findings and results within a reas<strong>on</strong>able timeframeto initiate follow-up activities in <str<strong>on</strong>g>the</str<strong>on</strong>g> most promising areas. In additi<strong>on</strong> to <str<strong>on</strong>g>the</str<strong>on</strong>g> Call for Proposals,participants were invited to elaborate ideas in <str<strong>on</strong>g>the</str<strong>on</strong>g> area <str<strong>on</strong>g>of</str<strong>on</strong>g> <strong>satellite</strong> navigati<strong>on</strong>, its applicati<strong>on</strong>s andvalue-added services. The ideas were not bound to <str<strong>on</strong>g>the</str<strong>on</strong>g> main topics <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> Call for Proposals, butwere open to address all areas where <strong>satellite</strong>-based navigati<strong>on</strong> is expected to play a major role.The project proposals and ideas received by <str<strong>on</strong>g>the</str<strong>on</strong>g> GALILEO C<strong>on</strong>tact Point Austria are to beevaluated by an internati<strong>on</strong>al expert committee. A sec<strong>on</strong>d Call for Proposals with focus <strong>on</strong>applicati<strong>on</strong>s in <str<strong>on</strong>g>the</str<strong>on</strong>g> areas <str<strong>on</strong>g>of</str<strong>on</strong>g> tourism and leisure time, pers<strong>on</strong>al navigati<strong>on</strong>, search- and rescueservices, and fleet management, was expected to open <strong>on</strong> 1 April 2004. The Call would close <strong>on</strong> 7June 2004. Instituti<strong>on</strong>s or entities interested in participating in <str<strong>on</strong>g>the</str<strong>on</strong>g> ARTIST-Programme wereinvited to c<strong>on</strong>tact <str<strong>on</strong>g>the</str<strong>on</strong>g> GALILEO C<strong>on</strong>tact Point Austria at Austrian Space Agency (ASA) .58
326. The regi<strong>on</strong>al activity in <str<strong>on</strong>g>the</str<strong>on</strong>g> field <str<strong>on</strong>g>of</str<strong>on</strong>g> GNSS is reflected in various c<strong>on</strong>ferences. From 1991to 1999, biennial scientific symposia titled “GPS in Central Europe” were held in Hungary withparticipants from <str<strong>on</strong>g>the</str<strong>on</strong>g> regi<strong>on</strong> and o<str<strong>on</strong>g>the</str<strong>on</strong>g>r areas. The topics covered included geodesy, heightdeterminati<strong>on</strong>, geodynamics, reference frames, meteorology, differential GPS, instrumentati<strong>on</strong>,data analysis techniques and several o<str<strong>on</strong>g>the</str<strong>on</strong>g>r issues. The proceedings <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> symposia werepublished by <str<strong>on</strong>g>the</str<strong>on</strong>g> Satellite Geodetic Observatory <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> Institute <str<strong>on</strong>g>of</str<strong>on</strong>g> Geodesy and Cartography,Hungary (www.sgo.fomi.hu) and <str<strong>on</strong>g>the</str<strong>on</strong>g> Institute <str<strong>on</strong>g>of</str<strong>on</strong>g> Geodesy and Geodetic Astr<strong>on</strong>omy, WarsawUniversity <str<strong>on</strong>g>of</str<strong>on</strong>g> Technology, Poland (gik.pw.edu.pl/igga.html) in <str<strong>on</strong>g>the</str<strong>on</strong>g> Reports <str<strong>on</strong>g>of</str<strong>on</strong>g> Geodesy series.327. Ano<str<strong>on</strong>g>the</str<strong>on</strong>g>r important event in Austria was <str<strong>on</strong>g>the</str<strong>on</strong>g> holding <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> European Navigati<strong>on</strong>C<strong>on</strong>ference <strong>on</strong> Global Navigati<strong>on</strong> Satellite Systems, hosted by OVN <strong>on</strong> behalf <str<strong>on</strong>g>of</str<strong>on</strong>g> EUGIN, from22 to 25 April 2003 at <str<strong>on</strong>g>the</str<strong>on</strong>g> C<strong>on</strong>gress Centre in Graz, Styria (ENC – GNSS, www.<strong>gnss</strong>2003.com).The ENC – GNSS 2003 was <str<strong>on</strong>g>the</str<strong>on</strong>g> seventh c<strong>on</strong>ference in <str<strong>on</strong>g>the</str<strong>on</strong>g> GNSS series held under <str<strong>on</strong>g>the</str<strong>on</strong>g> auspices<str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> European Group <str<strong>on</strong>g>of</str<strong>on</strong>g> Institutes <str<strong>on</strong>g>of</str<strong>on</strong>g> Navigati<strong>on</strong> (EUGIN). The c<strong>on</strong>ference focused <strong>on</strong> <str<strong>on</strong>g>the</str<strong>on</strong>g>actual status as well as <strong>on</strong> future developments in <strong>satellite</strong> navigati<strong>on</strong> <strong>systems</strong>, with specialemphasis <strong>on</strong> GALILEO.328. In Italy, <str<strong>on</strong>g>the</str<strong>on</strong>g> use <str<strong>on</strong>g>of</str<strong>on</strong>g> <strong>satellite</strong>-based navigati<strong>on</strong> <strong>systems</strong> is c<strong>on</strong>tinuously growing in <str<strong>on</strong>g>the</str<strong>on</strong>g>various transport sectors: civil aviati<strong>on</strong>, maritime and ground (road and rail) as well as innumerous fields <str<strong>on</strong>g>of</str<strong>on</strong>g> “n<strong>on</strong>-transport” applicati<strong>on</strong>s such as geodesy, agriculture, GIS, and RTK.329. The Italian Ministry <str<strong>on</strong>g>of</str<strong>on</strong>g> Transport, based <strong>on</strong> <str<strong>on</strong>g>the</str<strong>on</strong>g> promoti<strong>on</strong>al activities c<strong>on</strong>ducted by <str<strong>on</strong>g>the</str<strong>on</strong>g>Italian Space Agency and <str<strong>on</strong>g>the</str<strong>on</strong>g> Italian Institute <str<strong>on</strong>g>of</str<strong>on</strong>g> Navigati<strong>on</strong>, has undertaken an attempt topromote <str<strong>on</strong>g>the</str<strong>on</strong>g> debates for a nati<strong>on</strong>al Radio Navigati<strong>on</strong> Plan, allowing to co-ordinate radi<strong>on</strong>avigati<strong>on</strong> <strong>systems</strong> <strong>on</strong> <str<strong>on</strong>g>the</str<strong>on</strong>g> territory in a harm<strong>on</strong>ised and cooperated fashi<strong>on</strong>.330. The Italian Space Agency (ASI- www.asi.it), being <strong>on</strong>e <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> major c<strong>on</strong>tributors to <str<strong>on</strong>g>the</str<strong>on</strong>g>European Programme GALILEO, is fostering <str<strong>on</strong>g>the</str<strong>on</strong>g> development <str<strong>on</strong>g>of</str<strong>on</strong>g> Applicati<strong>on</strong>s <str<strong>on</strong>g>of</str<strong>on</strong>g> SatelliteNavigati<strong>on</strong> in co-operati<strong>on</strong> with Governmental Operati<strong>on</strong>al Entities (ENAC, ENAV, Italian CoastGuard) in order to pave <str<strong>on</strong>g>the</str<strong>on</strong>g> way for GALILEO.331. As far as <str<strong>on</strong>g>the</str<strong>on</strong>g> Reference Networks for precise positi<strong>on</strong>ing is c<strong>on</strong>cerned, <str<strong>on</strong>g>the</str<strong>on</strong>g> Italian SpaceAgency is owner <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> main network in Italy, which is part <str<strong>on</strong>g>of</str<strong>on</strong>g> an internati<strong>on</strong>al geodesy network.Research activities332. The use <str<strong>on</strong>g>of</str<strong>on</strong>g> GPS techniques in Portugal goes back to <str<strong>on</strong>g>the</str<strong>on</strong>g> 1980s, when a large observati<strong>on</strong>campaign was organised by <str<strong>on</strong>g>the</str<strong>on</strong>g> Faculty <str<strong>on</strong>g>of</str<strong>on</strong>g> Sciences, University <str<strong>on</strong>g>of</str<strong>on</strong>g> Porto, in co-operati<strong>on</strong> with <str<strong>on</strong>g>the</str<strong>on</strong>g>Geodetic Institute, University <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> Armed Forces <str<strong>on</strong>g>of</str<strong>on</strong>g> Munich, to m<strong>on</strong>itor plate-tect<strong>on</strong>icmovements in <str<strong>on</strong>g>the</str<strong>on</strong>g> Azores-Gibraltar area .333. Since <str<strong>on</strong>g>the</str<strong>on</strong>g>n, many research projects have been carried out, going from studies <str<strong>on</strong>g>of</str<strong>on</strong>g> platetect<strong>on</strong>ics and volcanism to <str<strong>on</strong>g>the</str<strong>on</strong>g> study <str<strong>on</strong>g>of</str<strong>on</strong>g> high atmosphere from <strong>on</strong>-board GPS measurements,passing by different projects <strong>on</strong> Earth, including navigati<strong>on</strong> and attitude determinati<strong>on</strong> andc<strong>on</strong>trol. In some cases, besides GPS, also <str<strong>on</strong>g>the</str<strong>on</strong>g> GLONASS system has been used. As a result, alarge number <str<strong>on</strong>g>of</str<strong>on</strong>g> scientific papers have been published and several Ph.D. <str<strong>on</strong>g>the</str<strong>on</strong>g>sis have been writtenin Portuguese universities as well as in research institutes. At present, attenti<strong>on</strong> is also beinggiven to <str<strong>on</strong>g>the</str<strong>on</strong>g> development <str<strong>on</strong>g>of</str<strong>on</strong>g> GNSS and GALILEO.59
