Summary:

Determination of movements of the land surface or technical objects is rea-lized by means of geodetic measurement methods. This task consists in numerical processing the results of the series of periodic measurements. The paper presents two proposals for the determination of movements. The first of these amounts to the total adjustment of all the observations taking the time of their performance into consideration. The second, alternative method is based on the setting up of the functional model for the observation differences. The presented theoretical rela-tionships (exact functional compounds) have been supported by numerical example that allows someone to evaluate the effectiveness of proposed solutions.
