National Report of Sweden to the NKG General ... - Lantmäteriet

2Observatory at Chalmers University ofTechnology. Totally 50 EPN stationsconcentrated to northern Europe areprocessed with the Bernese GPSsoftware version 5.0, see Figure 1.1.This means that eight stations havebeen added to the NKG EPN LAC subnetworksince the last NKG GeneralAssembly four years ago. Both weeklyand daily solutions based on final IGS 9products are processed. Lantmäteriethas also represented NKG at the fifth,and sixth EUREF 10 LACs Workshops,which were held in 2006 and 2008. Thisis also the plan for the seventhworkshop in autumn 2010.The NKG EPN LAC will also contributeto the EPN reprocessing with solutionsbased on both the Bernese GPSSoftware and GAMIT. Bernesesolutions for the pilot reprocessing ofthe year 2006 have been processedduring 2009/2010.1.2.3 EGNOS 11The EGNOS RIMS 12 that wasinaugurated at Lantmäteriet in Gävlealready during 2003 has beensuccessfully supported by Lantmäterietsince then.1.2.4 Swedish Radio Navigation PlanThe Swedish Radio Navigation Plan of2009 is published by the SwedishMaritime Administration. Lantmäteriethas taking part in the working groupwithin the Swedish Board of RadioNavigation that has produced the plan.Since early 2010, Lantmäteriet chairsthe Swedish Board of RadioNavigation.1.2.5 Nordic Positioning ServiceLantmäteriet has participated in theproject Nordic Positioning Service. Themajor purpose was both to exchangedata between the networks ofpermanent reference stations inDenmark, Norway and Sweden and toestablish common positioning services.The project also implied exchange ofknowledge in the fields of operationand applications of networks ofpermanent reference stations.Figure 1.1: The NKG EPN LAC subnetworkof 50 permanent GNSS stations.1.3 Network of permanentreference stations (SWEPOS)SWEPOS is the Swedish network ofpermanent GNSS stations (Jämtnäs etal., 2010), see www.swepos.com.The purposes of SWEPOS are to:- Provide single- and dual-frequencydata for relative GNSS measurements.9IGS = International GNSS Service10EUREF = the IAG Reference Frame Subcommission forEuropeIAG = International Association of Geodesy11EGNOS = European Geostationary Navigation OverlaySystem12RIMS = Ranging and Integrity Monitoring Station
