Evaluation of accuracy of position coordinates’ determination in respect to floating marks, with free adjustment method applied, has been a target of the paper. General theory of geodesic adjustment – classical one based on least squares method and free adjustment – is presented in its first part. Main part contains description of the research. It was conducted based on geometric navigational structure which elements had been formed by beacons placed in the Bay of Gdańsk. It consisted in simulating results of measurements made in respect to marks of this structure (bearings and distances) and calculating the position coordinates based on them, as well as its accuracy. The calculations were made with the method of classical geodesic adjustment and free adjustment applied. Discussion about obtained results of the research and general conclusions are given in the ending part of the article.
