Location of the EISCAT facilities
Document Actions
The coordinates of the EISCAT facilities in various geographical and geomagnetic coordinate systems.
The geographic positions are generally based on a satellite survey from 1981 and agreed with the positions used inside EROS. The Tromsø geographic position comes from a later GPS measurement while the Longyearbyen latitude and longitude come from a measurement with a hand held GPS.
The geomagnetic values are calculated for 1 January, 2010, using the DGRF/IGRF model. The values were retrieved 5 February, 2010.
