May 2024 Storm Impact on Ground-based and Spaceborne GPS/GNSS

Ground-based GNSS receiver networks and LEO satellite-based GNSS receivers have been playing a critical role in observing the impact of solar geomagnetic storm impacts on the ionosphere. This is especially true for the May 10-11, 2024 geomagnetic storm. In this presentation, we will share the observed impacts from low rate GNSS receiver networks, high rate scintillation receivers, commercial small satellite constellation generated the radio occultation measurements, and precise orbit determination receivers on board scientific satellites. The results will also be compared with previous storms to show the diverse behavior in the storm impacts. Finally, insights into the impact on GPS/GNSS receivers operation will also be shared.
