GPS‐SBAS‐Based Orbit Determination for Low Earth Orbiting Satellites
International Journal of Aerospace Engineering, Volume 2023, Issue 1, 2023., 2023 A space‐based augmentation system (SBAS) provides real‐time GNSS correction signals via geostationary satellites for near‐ground GNSS users. To use the SBAS correction for low Earth orbit (LEO) satellites, the correction, especially the ionosphere correction, must be adjusted for the LEO altitude.
