Scheinbare Koordinatenänderungen von GPS-Referenzstationen:
Einfluss von Auswertestrategien und Antennenwechseln
Abstract
Different GPS observables and antenna changes can result in apparent coordinate changes of GPS reference stations, i.e. offsets in the coordinate series although the GPS antenna remains in the same geometrical place. In this article, we propose a classification of these variations into two categories, namely mathematical and physical effects. This approach will help to better understand the reasons for such coordinate changes. Based on a data set consisting of nine GPS antenna types the effects are quantified and discussed extensively. Subsequently, the gained insights are transferred to coordinate discrepancies in the so called local ties of ITRF, and a recommendation to reduce this problem is given.
