Precision Providing of Motorized Total Station Topcon GMT-100 according to ISO 17123-3 and 17123-4

U radu se opisuje postupak određivanja preciznosti mjerenja horizontalnih pravaca i duljina motoriziranom mjernom stanicom Topcon GMT-100, prema važećim ISO normama 17123-3 i 17123-4. Za određivanje preciznosti horizontalnih pravaca mjereno je pet pravaca u tri girusa, u četiri serije mjerenja. Mjerenje duljina provedeno je na Kalibracijskoj bazi Geodetskog fakulteta u Zagrebu. Duljine su mjerene između sedam stupova, u svim kombinacijama. Rezultati ispitivanja empirijska su standardna odstupanja horizontalnih pravaca i duljina. Izračunana je i adicijska korekcija instrumenta.The paper explains field procedures for determining the precision of the horizontal directions and distances of motorized total station Topcon GMT-100, according to current ISO standards 17123-3 and 17123-4. For determining the precision of horizontal directions five directions in three sets and in four series have been measured. Measuring of horizontal distances has been carried out on calibration baseline of the Faculty of Geodesy in Zagreb. Distances were measured between seven pillars. All combinations have been measured. Experimental standard deviation of horizontal directions and distances, and zero point correction are the results of this examination
