Using the network of repeat stations established in 1994 on the territory Serbia, we carried out in 2008 field measurements at 14 repeat stations. Since 1960 only one terrain variometer has been used, and now, for the first time, we are using two variometers. Each station was occupied for at least five days for absolute measurements (D, I and F) and variations were continually recorded by two variometers. We are using Magson’s flux gate and Geomagnetic System suspended dIdD type magnetometers for recordings at the site. Therefore, the working procedure was very much alike the one at the geomagnetic observatory. We shell explain specific features of both instruments (operation, temperature, sensor’s characteristics etc.). Also the geomagnetic charts of D, H and Z for Serbia will be presented.
