“Efficient portable digital zenith camera (accuracy ~0.1 arcsec) was developed at the Institute of Geodesy and Geoinformatics (GGI) of the University of Latvia by a team that previously specialised in developing software and hardware for astrogeodetic cameras and satellite laser ranging devices. The innovation of Latvian DZC development is based on recent achievements in various sciences – fast and accurate digital imaging technology, extremely accurate super-large reference star coordinate catalogues, very sensitive electronic tilt meter technologies, available high-precision Earth rotation parameters, and GNSS-based high-precision positioning and timing capabilities.”
