Abstract

A nationwide project is undertaken since a few years with the purpose to upgrade the geodetic infrastructure by setting up a wide real-time GNSSContinuously Operating Reference Stations (CORS) network. In this perspective a study has been inderteken in the setting of this assignment with the purpose to select eligible sites of the GNSS/CORS network infrastructure. The technical selection criteria were based essentially on the assessment of GNSS data received by already operating GNSS sites. Two stations have been selected to performthisinvestigation based on signal interference and multipath evaluation and monument stability analysis through the post-processing of GNSS data supplied by these GNSS sites, there are located in Algiers in the north and Ouargla in the south, namely DZAL and OGLA respectively.
