Field observations for astronomical vertical deflection determination is a specific part of geodetic astronomy and as such it needs special instrumentation. Mobile Automatic Astronomical System No 1. (MAAS-1) was developed on Brno University of Technology. It is based on motorized total station Topcon GPT 9001A supplemented by external CCD camera and portable computer. MAAS-1 measuring system is designed for fast and precise determination of astronomical coordinates intended for vertical deflections computation. The process of measurement is fully automated which makes possible to eliminate personal influences on results, thus eliminating so called “personal errors”. MAAS-1 was thoroughly tested with highly satisfactory results. The system was found to be reliable, user friendly and without significant faults. It’s results were compared with results of several other precise astrogeodetic instruments (notably Cirkumzenital VUGTK 100/1000 and digital zenith camera TZK2-D). External accuracy of results – vertical deflections components – was found to be in range 0.2–0.3 arc seconds for standard one hour field observation. MAAS-1 was employed in several experimental projects. Till now, more than 100 astrogeodetic vertical deflections has been determined.
