The paper describes a software called ATControl which is based on the Matworks Matlab high-level programming language. This software is under constant development by the author in order to collect geospatial data by measuring with the absolute laser tracker Leica AT40x (AT401, AT402). Commercially available software solutions are shortly reviewed and the reasons for developing the new controlling application are discussed. Advantages of ATControl concerning metrological traceability of measured distances are stated. Key functional features of software are introduced.
