摘要： 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.

摘要： Systems and methods for using SBAS delay measurements to mitigate ionospheric error are provided. In an embodiment, an array of ionospheric delay measurements of a GNSS is provided, wherein a pierce point is associated with each delay measurement in the array. Further, at least one first element in the array and at least one second element in the array that has a different pierce point than the at least one first element are selected and it's determined whether the difference between the delay measurement of the at least one first element and the delay measurement of the at least one second element is less than a threshold. A level of inflation of error due to geometric screening techniques is adjusted if the difference between the delay measurement of the at least one first element and the delay measurement of the at least one second element is less than the threshold.
