The New REGINA Stations at Gavdos and Gadanki

Clément Gazzino, Nicolas Lelarge, Laurent Jolivet

Abstract:	Ground station networks are mandatory for monitoring the Global Navigation satellites health status or for the computation of their precise ephemeris and clocks. The french space agency (CNES) has set up, in cooperation with the National Institute of Geographic and Forest Information (IGN), a GNSS ground station network called REGINA. Recently, this network has evolved with the addition of two new stations at Gavdos, Greece, and Gadanki, India. The proposed article reviews the performances of this network and evaluates the new stations.
