Zenith camera information


Digital zenith camera system of University of Hannover for the observation of the plumb line and vertical deflection

A zenith camera is an astrogeodetic telescope used today primarily for the local surveys of Earth's gravity field. Zenith cameras are designed as transportable field instruments for the direct observation of the plumb line (astronomical latitude and longitude) and vertical deflections.[1]
