Site information 2.1 Site location information City or Town : Ny-Alesund State or Province : Svalbard Country : Norway Tectonic plate : Europe Approximate position X coordinate (m) : Y coordinate (m) : Z coordinate (m) : Latitude (deg) : 78.93 deg. N Longitude (deg) : 11.87 deg. E Elevation (m) : 79.8 m Source of position : ITRF 96 Additional information : Several teams are investigating this question right now. The problem is (as we understand) that their coordinates of the control network do not agree to accepteptable values. As soon as this problem is solved, and we get the coordinates of the antenna's rotation axes, we will send an update to the data base. 2.2 Site local survey network information Person responsible : Knut Gjerde Most recent survey date : July 2010 Number of reference markers : 6 close, 9 more distant Type of marker : 6 pillars, the rest is ground markers.
