摘要	The dual-frequency multi-constellation satellite-based augmentation system (DFMC SBAS) plays a crucial role in many fields, such as civil aviation and other safety-critical applications. To analyze the performance of the third generation of the BeiDou navigation satellite system (BDS-3) dual-frequency SBAS services in global major regions and the enhancement of navigation service performance by multi-Global Navigation Satellite System DFMC SBAS, four schemes are designed to conduct experiments using user end positioning in China (CHN), Europe (EUR), and Australia (AUS), and the results are analyzed under Approach with Vertical guidance I (APV-I) and Category I Precision Approach (CAT-I). In terms of the number of enhanced satellites, user range error, positioning accuracy, and DFMC SBAS service integrity, the results show that the positioning performances of the BDS-3 DFMC SBAS in the horizontal and vertical directions are 0.60 and 1.12 m for the CHN region, 0.87 and 1.39 m for the EUR region, and 0.64 and 1.11 m for the AUS region. In the CHN and AUS regions, the horizontal and vertical accuracies are comparable and better than those in the EUR region. Under the APV-I performance index, except for stations at the edge of the service range in the CHN and AUS regions, the availability and continuity of all stations were 100% and over 99% in the EUR region. The BDS-3 + Galileo + GPS DFMC SBAS service can significantly improve the positioning accuracy compared to a single constellation. Under the APV-I performance index, the availability and continuity of all stations in the three regions reached 100%, which also satisfied the minimum requirement of CAT-I service availability (99%).
