Overview • • Introduction EUPOS® LATPOS and EUPOS® - RIGA Elevations – Base station Results of Geometric Levelling Elevations - NGK 2008 campaign, Bernese 5. 0 Comparison Conclusion

Current situation • EUPOS® network include about 900 reference stations in 17 European countries • EUPOS® reference stations provide DGNSS correction data for real time positioning and navigation and observation data for geodetic post processing • EUPOS® fulfils all accuracy requirements of geodesy and navigation

EUPOS®

LATPOS 19 base stations within territory of Republic of Latvia. Base stations are sending information to service center in Riga. LATPOS users receive real-time information via GPRS or GSM.
