Use of the Finnish Permanent GPS Network (Finnnet) in Regional GPS Campaigns
The Finnish Geodetic Institute has established a network of 12 permanent GPS-stations in Finland (FinnNet). The planning of the network started during winter 92/93. The first stations were installed in 1994 and the last one was built in the autumn of 1996. The stations are equipped with geodetic Ashtech Z-12 receivers and Dorne Margolin type antennas. All the stations are working fully automatically. The network is used as a 1st order reference frame in Finland for GPS users, for crustal dynamics studies and for providing RTCM corrections in real time applications.
FinnNet is used as a reference frame or as a source of data for numerous national and international GPS campaigns and projects like DOSE (Dynamics of the Solid Earth), BSL (Baltic Sea Level), BIFROST (Baseline Inferences for Fennoscandian Rebound Observations, Sea Level and Tectonics), EUVN (European Vertical GPS Reference Network), and EUREF permanent GPS Network.
We will introduce FinnNet and its function in Finland, present the first results of the EUREF-FIN campaign and give an overview of the projects FinnNet has taken part in. We will discuss in general how permanent networks can be used in regional GPS measurements and call into question the function and need of large episodic GPS field campaigns in the future.
