EO Portal Info
Orbit Type Inclined, non-sun-synchronous Orbit Period 101 minutes
Orbit Sense N/A Orbit Inclination 81 deg
Orbit Altitude 450 km Orbit Longitude
Orbit LST Repeat Cycle
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 1500 km. Note: MDA is the owner and University of Calgary is the operator.
