Originální abstrakt

The precision of geodetic measurement results steadily increases. Elimination of various systematic effect types is necessary in order to achieve the highest accuracy demands. Individual absolute calibration of geodetic GNSS antennae is the best method of elimination of systematic effects caused by the antennae characteristics. The calibration is made today mainly by means of a robot – a movable arm with an antenna on its top. That kind of a device, StAnCa (Station Antenna Calibration), is currently developed in the authors’ home Institute. Knowledge of the antenna mounting screw precise positions in the time of GNSS observations is crucial for the following numerical processing. Therefore several testing measurements have already been carried out. The first group of measurements was focused on small deviations and axes irregularities in the construction of the moveable arm. The second group of measurements was aimed at irregularities in arm's movement. Classic geodetic methods utilizing theodolites as well as the own developed photogrammetric method were used. The third type of measurement was devoted to verifying synchronization of arm's movement with UTC. Independent method utilizing state of the art astronomical device MAAS-1 was used for this purpose.
