Follow-Up Visit to Ascension Island 2023

After a few weather-related delays, BC/ISR scientists Ted Beach, Dima Paznukhov, & Matt Proctor were able to travel to Ascension Island (in the middle of the Atlantic Ocean) for upgrading and installation of additional ground-based systems for recording satellite signals.  The original set was installed in December 2022, and the latest upgrades and additions will enable further study of the impact caused by equatorial plasma bubbles in the ionosphere on satellite radio transmissions, primarily GNSS signals. During the visit, which was during the strongest ionospheric disturbance activity period, a full-scale measurement campaign on data collection was carried out, allowing acquisition of a large volume of data (tens of TB) which is currently being analyzed by our scientists at BC.
