Abstract

ESA SISNeT (Signal in Space through Internet) technology allows to use the EGNOS WADGPS (Wide Area Differential GPS) corrections through a password protected access via Internet to a DS (Data Server). The DS is actually loated at Nordwijck (The Nederlands). This technology allows the application of the WADGPS corrections also in those areas where the Geostationary Satellites downlinking the SIS (Signal in Space) are not visible. This is particularly important to guarantee Car Navigation in urban areas. Kinematic Real Time experiments have been carried out in order to test the performances of the System, and the obtainable accuracies. Two geodetic receivers, a Trimble L1/L2 receiver and a Novatel MILLennium one, WAAS/EGNOS enabled, updated with a firmware version allowing the input of SIS into serial ports, were used for the experiments. The real time kinematic positions obtained using the WADGPS corrections through SISNeT were compared with the post-processed interferential ones showing very good accuracies even in the vertical components.
