Croatian Geomagnetic Repeat Stations Network

Prikazana je uspostava mreže primarnih sekularnih geomagnetskih točaka na teritoriju Republike Hrvatske. Točke za istraživanje sekularne varijacije projektirane su sukladno preporukama Coordination Committee for Common European Repeat Station Surveys, kriterijima International Association of Geomagnetism and Aeronomy – IAGA te iskustvima europskih zemalja. Konačne lokacije sekularnih točaka izabrane su evaluacijom kriterija na samom terenu. U tu svrhu razvijene su i testirane metode određivanja gradijenata totalnog intenziteta uključujući potrebnu programsku podršku. Iz ispitivanja različitih materijala uslijedio je izbor kamene stabilizacije. Točke mreže stabilizirane su ukopavanjem stabilizacije standardnim geodetskim postupcima. Status svake točke mreže dokumentiran je obrascima Položajnog opisa i Geomagnetskih parametara.The establishment of primary geomagnetic repeat stations on the territory of the Republic of Croatia was presented. Stations for secular variation study were designed in accordance to recommendations of the Coordination Committee for Common European Repeat Station Surveys, criteria of the International Association of Geomagnetism and Aeronomy - IAGA, as well as experiences of the European countries. Final locations of the repeat stations were determined by the field evaluation of the criteria. For that purpose, the total intensity gradients survey methods, along with required software, were developed. Following the testing of various materials, the rock monument was selected. The network points were setup by digging in the monument using standard geodetic procedures. The Status of the each network point was documented in Position Description and Geomagnetic Parameters forms
