Abstract. Geodetic instruments need to be calibrated and examined regularly in order to insure the accuracy of measuring results. However, the process of calibrating of geodetic instruments is performing in laboratories while the measurements are performing in real conditions. As a consequence, the results of etalonizing of geodetic instruments do not represent the conditions which may occur in different projects in which those geodetic instruments could be used. Bearing in mind this fact parallel with the fact that metrological characteristic influence the results of production measurements, the need of their determination in real projects appears. The interesting questions is “if it is possible to use results of production measurements obtained from realized projects in order to determine the metrological characteristics of used geodetic instruments?” This paper intends to discuss some aspects of metrological characteristics of geodetic instruments, based on measurements from realized project, determination.
