N2 - Region Augmentation System (RAS) is a new kind of Ground-Based Augmentation System (GBAS), and it is proposed by National Key Laboratory of CNS/ATM, Beihang University. In RAS, multi-GBAS is distributed on a region whose radius is about 200km, and the aircraft flying in the region could use the information broadcasted from one or more other GBAS stations to improve its integrity, for example to monitor the ionospheric anomaly. The primary goal of this paper is to discuss the ephemeris integrity risk of RAS, especially the risk cause by double satellite ephemeris fault. Based on the single ephemeris fault protection level algorithm of GBAS, an algorithm of double satellite ephemeris fault protection level is proposed. Meantime, the Non-protection level integrity risk is analyzed and discussed. Finally, based on the RAS frame, some simulations are carried out and the corresponding results are discussed.
