The dataset contains coordinates of the position of the stations from the Reference geomagnetic network of secular stations.Data is collected by field work during the State geomagnetic survey of secular stations.
The reference geomagnetic network of secular stations is established in 1957 to a wider extent than today, as part of the regional survey of the SFRJ. Today's Reference Geomagnetic Network secular stations contain 14 stations and a Geomagnetic Observatory Grocka (GCK), where the distance between points are 50-70 km. The Grocka Geomagnetic Observatory (GCK) is part of the Reference geomagnetic networks of secular stations.
