This paper reports some results of a research performed just before the elimination of the SA in the GPS signals, and it remain valid for the high accuracy Differential and RTK operations. The research is based on the availability in the CEI area of several radio diffused RTCM corrections. Some of them are simultaneously present in some areas, thus allowing static and kinematic analyses of their accuracy and continuity. The paper refers experiments with two Low Frequency transmitted signals, i.e. ALF and LF signal from Podebrady (Prague) and one FM transmitted signal: DARC. Moreover two WAAS corrections have been tested in Trieste coming from the Geostationary satellites 120 and 122, the former visible at 30 degrees of elevation and the latter at 6 degrees. Since these last experiment have been performed during the first week without SA, a comparison with the stand alone GPS positions have been allowed and are here reported.
