"The Canadian CASSIOPE satellite, operated by the University of Calgary, carries the Enhanced Polar Outflow Probe (e-POP) suite of scientific instruments to study the ionosphere, where space meets the upper atmosphere. The instruments collect data about the effects of solar storms and, more specifically, their harmful impact on radio communications, satellite navigation and other space and ground-based technologies.
The eight science instruments include imaging plasma and neutral particle sensors, magnetometers, radio wave receivers, dual-frequency GPS receivers, CCD cameras, and a beacon transmitter. The imaging plasma sensors (SEI and IRM) measure particle distributions and the magnetometers (MGF) measure field aligned currents on the time scale of 10-ms and spatial scale of ~100 m. The neutral mass and velocity spectrometer (NMS) measures the density and velocity of major atmospheric species. The CCD cameras (FAI) perform auroral imaging on the time scale of one second. The radio wave and GPS receivers (RRI and GAP) perform near real-time imaging studies of the ionosphere, in conjunction with ground-based radars, as does the beacon transmitter (CER), in conjunction with ground receiving stations.
Data from these scientific instruments are available on the University of Calgary website: https://epop.phys.ucalgary.ca/data/). You cans also download here an extract of the telemetry data that lists a variety of CASSIOPE positions, velocities and altitudes based on UTC time.
