USING SPACE BASED AUGMENTATION SYSTEM (SBAS) EPHEMERIS SIGMA INFORMATION TO REDUCE GROUND BASED AUGMENTATION SYSTEMS (GBAS) EPHEMERIS DECORRELATION PARAMETER
USING SPACE BASED AUGMENTATION SYSTEM (SBAS) EPHEMERIS SIGMA INFORMATION TO REDUCE GROUND BASED AUGMENTATION SYSTEMS (GBAS) EPHEMERIS DECORRELATION PARAMETER
A method of using space based augmentation system (SBAS) ephemeris data in conjunction with a ground based augmentation systems (GBAS) station is provided. The method includes integrating a space based augmentation system (SBAS) receiver in the GBAS station; receiving an industry-standard message type via the SBAS receiver at the GBAS station; consuming, at the GBAS station, the SBAS ephemeris data from the industry-standard message type associated with satellites in view of the GBAS station. The industry-standard message type includes SBAS ephemeris data associated with satellites in a global navigation satellite system (GNSS). The method further includes, based on the consuming, improving error bounds to GBAS broadcast ephemeris decorellation parameters broadcast from the GBAS station and reducing time to reintroduce a satellite in the GNSS.
