Description
In the equatorial sector, ionospheric irregularities are known to impact radio-based technologies, such as the Global Navigation Satellite System (GNSS), by delaying, scattering and diffracting, signals travelling through them. Satellite Based Augmentation Systems (SBAS), broadcasting corrections to single-frequency GNSS users including ionospheric corrections, present challenges at such latitudes. This preliminary study will show the potential impact of the well-known Gannon Storm (May 10th, 2024) on navigation algorithm performance designed for SBAS at equatorial latitudes. Space weather operational indices tailored to GNSS/SBAS technologies will also be discussed.
