A New 10-km GPS Reference Network of the Republic of Croatia

A new 10­km GPS reference frame of the Republic of Croatia has been set up in 2003. based on the official Croatian EUREF GPS network, presented and accepted during the EUREF 2001 meeting in Dubrovnik, a densification with almost 1000 GPS points, covering entire territory of Croatia, was realized. This paper deals with detailed description of data processing, adjustment and result analysis. Since the new established 2nd order GPS network is not only the practical realization (frame) of the ETRS89 datum for the Republic of Croatia, but also will be used as basis for other GPS and classical terrestrial geodetic measurements, it is planed to keep observing it every 4-5 years. Therefore, even more interesting results, especially time varying of co-ordinates, could be expected in the near future.
