Space Weather, Volume 21, Issue 9, September 2023., 2023 Abstract This paper investigates the effects of a minor G1 Co‐rotating Interaction Region (CIR)/High‐Speed Stream (HSS)‐driven geomagnetic storm that occurred on (13–14 October 2018), during deep solar minimum. We used simultaneous observations from multiple instruments, namely; ground‐based Global Navigation Satellite Systems (GNSS) receivers, a ...

PPP at Low Latitudes With Ionospheric Model Exclusively Based on Single Frequency GNSS Measurements
Space Weather, Volume 21, Issue 8, August 2023., 2023 Abstract Single frequency users of the Global Navigation Satellite System (GNSS) should correct the ionospheric delay to obtain positioning solutions. A valuable source of ionospheric delay corrections is the global ionospheric models (GIMs) of Vertical Total Electron Content.
