Abstract：Based on the requirement of 99.9% envelope probability of the SF integrity parameter, this paper proposes a method to determine the service range of the satellite-based augmentation system(SBAS). Through the analysis of the integrity information broadcast by EGNOS in Europe, the service range of EGNOS calculated using this method is basically consistent with the service range announced. This method will provide support for the determination of the service range of the Beidou satellite-based augmentation system(BDSBAS) and promote the continuous improvement of the service performance of the BDSBAS.
