Summary(Plain Language Summary, not published)
Space weather refers to the dynamic conditions on the Sun and in the space environment, that can affect critical infrastructure. NRCan operates the Canadian Space Weather Forecast Centre and conducts research into space weather effects on power systems, pipelines, satellites, radio communications and GNSS to help Canadian industry understand and mitigate the effects of space weather. The statistical analysis of the space environment for use in satellite environment assessment has been done based on the data available at This includes description of the daily variations of proton and electron particle fluxes, total dose and other parameters on orbit. The interest in the space environment at highly elliptical high inclination orbit is because this is an orbit which covers most of the Northern territory and is most favourable to use for Canadian communication and weather missions. At the same time, models which are currently available for assessment of the environment do not provide good estimations for these locations.
