    Abstract
  • The Algerian Satellite-based Augmentation System (ALG-SBAS) is a satellite-based augmentation system (SBAS) based on the Algerian Communications Satellite 1 (Alcomsat-1), which is already in its official operational phase. In order to deeply understand the system service type and performance, this paper first introduces the system, and then evaluates the stability of the broadcast message of the geosynchronous orbit (GEO) satellite、Ionospheric delay correction accuracy、positioning accuracy and integrity. The results show that ALG-SBAS GEO satellite has strong stability. The ionospheric delay correction percentage is better than 87%. The positioning accuracy of The positioning accuracy of ALG-SBAS is significantly improved than that of GPS positioning, and the average positioning accuracy is increased by more than 39%. The average SBAS PPP 3D positioning accuracy of all stations is better than 0.45m. The positioning accuracy is compared with EGONS, and the results show that ALG-SBAS is slightly worse than EGONS. At the same time, the integrity of the station positioning results was analyzed, and no integrity risk events occurred in ALG-SBAS during the evaluation period. ALG-SBAS had an average availability of 99.9% at all stations in the Approach with Vertical Guidance-I(APV-I) phase. The service performance of the satellite-based augmentation system meets the single frequency service index and can provide single frequency SBAS service.
