Orbit requirements

2019-07-24

A low-earth circular orbit with a low inclination in an altitude of 550 to 650 km is preferred to be designed for the EP satellite, which should mainly satisfy the requirements of observing operations, near-real-time data downlink/uplink, and minimizing irradiation interference by energetic particles mostly concentrated in the radiation belts and South Atlantic Anomaly (SAA) areas. The lifetime of the EP satellite is required to be  3 years (5 years as a goal). The launch site will be in Xichang Satellite Launch Centre, which allows direct orbit injection with inclination lower than 30 degree.
