Auroral Scintillation Monitoring for GNSS

Auroral precipitation and associated electric currents affect accuracy of practical systems and services: e.g. global navigation satellite systems (GNSS), communication systems, and power systems. Such space weather hazards are important for Canadians due to increasing civilian and military activity in the Arctic, and increasing reliance on GNSS in the decade ahead. Ionospheric scintillation associated with the diffuse and discrete aurora can be particularly problematic for safety-critical operations. In order to better study, model and mitigate such effects, the University of Calgary leads the Transition Region Explorer (TREx) - the world's foremost auroral imaging facility for remote sensing the near-earth space environment.
