Abstract
Abstract GNSS receivers provide position information in a convenient way. However, additional orientation information cannot be fulfilled directly by a single antenna receiver up to now. This paper describes an approach for determining the orientation by a single GNSS receiver based only on its own static observations. As estimable base quantity, satellite positions are used as a reference in the moment of measuring. For that purpose the direction of each satellite s signal has to be known in relation to the antenna. In order to obtain this information, the signal strength of each satellite is measured. A systematical modulation of the signal, realized by rotating shading, is able to provide the required direction information approximately.
