Objectives and Applications
|
The ePOP probe observes the Earth’s ionosphere, where space meets the upper atmosphere. The instruments are used in conjunction with other satellite-based and ground-based instruments to analyze radio wave propagation in the ionosphere, measure the densities of ionized particles, and observe the aurora from space, all as they respond to space weather. The orbit is 450 km to 1250 km. Note: MDA is the owner and University of Calgary is the operator. Since December 2021, spacecraft is in slow rotation due to 3 damaged reaction wheels, but continues to collect science data.
