Abstract
The quality of DORIS stations environment based on POD residuals and signal power are regularly evaluated in the framework of the CNES SALP project. Time series and mapping projection of such data are analyzed and compared with POD standards evolution, with databases of material modifications, or in-situ photographies. As a result, some anomalies may be explained, and correcting actions can be taken accordingly by CNES and/or IGN (Institut Géographique National). Moreover, on a yearly base, a ranking of the DORIS stations is established, which enables to target the necessary site renovations. All these analyses allow to improve the quality of the DORIS network, and consequently the applications which rely on this high-accuracy observation network. This presentation summarizes the results obtained on the most recent evaluations.
