Abstract:	With the growing demand for accurate and reliable worldwide differential GPS positioning, there has been a significant move towards the use of real-time Satellite Based Augmentation Systems (SBAS) with wide area differential positioning capabilities. The US Wide Area Augmentation System (WAAS) and the European Geostationary Navigation Overlay system (EGNOS) are good examples of such a move. While these augmentation systems are developed to provide differential corrections and integrity data for satellite-based aviation, their signal will be available free of charge to all other non-aviation satellite positioning users in the respective coverage areas. Accordingly, nonaviation GPS users with WAAS/EGNOS-capable receivers will be able to do differential positioning across the United States and Europe with a free differential signal and achieve real-time 3 meter positioning. The new THALES DG16™ receiver evolved from the Ashtech® G12 receiver. The DG16 receiver is designed to track WAAS and EGNOS geostationary satellites and utilize their differential corrections in the navigation solution. The DG16 receiver can also track and utilize differential corrections through Beacon signals that are transmitted over the frequency range of 283.5 to 325 kHz. This paper presents the new THALES DG16 receiver and its DGPS performance results using WAAS/EGNOS and Beacon GPS correction signals.
