Satellite-Based Augmentation Systems (SBAS) argument the Global Navigation Satellite System (GNSS) by providing correction and integrity informations through GEO to meet the navigation requirement for all phases of civil flight, such as WAAS, EGNOS and so on. Now, BDS has entered global construction stage, so the availability assessment for BDSBAS is important for its planed application in civil aviation. The paper provides the key algorithms for service area prediction, establish the error transfer model from monitoring receiver, data processing center to user’s receiver. The simulation software is developed and verified by comparing with WAAS report. The service area of single frequency and dual frequency SBAS for different service level is simulated and analyzed, which can be a reference for BDSBAS in China.
