The paper describes the accredited magnetometer calibration facility of the Nurmijarvi Geophysical Observatory of the Finnish Meteorological Institute. The magnetometer calibration is part of the Magnetic Calibration and Test Laboratory of the observatory, which was accredited by the Finnish Accreditation Services (FINAS) in August 2007. The facility comprises a three-axes coil system installed in a non-magnetic building, temperature test system and an automatic control and measuring system. Both analog and digital outputs of magnetometers can be connected to the control electronics and the calibration procedure can be run fully automatic or with a predefined protocol. Accurate orientation with optical methods allows determination of the angles between magnetic and mechanical axes of the magnetometer. Experimental results of a calibration of a satellite magnetometer are included to demonstrate the calibration concept.
