Sažetak
The paper describes the determination of pillar coordinates at the calibration baseline of the Faculty of Geodesy, University of Zagreb by applying of GPPS service of CROPOS. GPS measurements have been made on 7 pillars of the calibration baseline: 0, 1, 2, 3, 5, 7 and 10. The I. order trigonometric point Brusnik was included into the measurements for the purpose of enlarging the length of the calibration baseline. The point Brusnik was selected because it is the point with the most precisely determined positional coordinates in Croatia. The measurements on the pillars of the calibration baseline were made in 8 sessions lasting 24 hours each, from July 25 till August 2, 2009, and on the point Brusnik in the first two sessions. The processing of GPS vectors and the adjustment of the pillar coordinates of the calibration baseline and of Brusnik were made with the software Trimble Total Control (TTC), v. 2.73. For the adjustment of coordinates there were 4 reference stations of CROPOS used: Bjelovar, Karlovac, Sisak and Zabok. As the final result the pillar coordinates of the calibration baseline and of Brusnik were given in ETRS89, epoch 1989.00, in the official positional datum of the Republic of Croatia.
