Abstract
For the sake of improving the accuracy, integrity, continuity and availability for civil aviation, etc., the satellite based augmentation system (SBAS) is widely used. Recently, the concept of dual-frequency augmentation signal is proposed. In order to analyze the service performance of SBAS and discuss the necessity of the dual-frequency SBAS (DFSBAS) signal, WAAS, EGNOS and MSAS are selected to analyze. They are evaluated in message type, accuracy and integrity of single-in-space (SIS), accuracy of position, integrity and availability of system and so on. The results show that in the service area, all systems can meet the requirement of non precision approach (NPA); in a part of area can satisfy the approach procedure with vertical I (APV-1). Finally, the simulation shows that dual-frequency SBAS signals will decrease the ranging error and improve the redundancy of system, improve the SBAS service to satisfy the requirement of.precision approach (PA).
