The new Arctic magnetic observatory at Pituffik in Greenland is strategically located in a sparsely monitored high-latitude region. Analysis of over a year of data, including baseline stability, temperature control, and calibrated magnetic field measurements demonstrates high data quality and confirms the observatory’s readiness for contribution to the international geomagnetic community.

We have adopted Polaris sighting as our azimuth observation at our observatories for a long time. This method, however, has some difficulties such as weather-dependent observation conditions. Therefore, we examined the satellite method and found that its precision was comparable to the Polaris sighting. We also found that a significant difference of about 10 arcseconds between them. This is due likely to a deflection of vertical, which is well known in the field of geodetic surveying.
