2 Detailed Survey on European LEO Missions

In order to identify a set of interesting spacecraft and their corresponding orbits to perform ADR and SDM, a detailed survey of European Low Earth Orbit (LEO) in-orbit spacecraft, under current design and planned future missions, has been performed. Because of liability reasons, only objects belonging to ESA, ESA member states and ESA cooperating states are considered. The information has been retrieved mainly from ESA DISCOS database [22] for in-orbit missions and mainly from eoPortal Satellite Missions Database ( https://directory.eoportal.org/web/eoportal/ ).

A detailed survey identified 130 missions with mass greater than 10 kg to be potential objects of study for ADR and SDM analyses. The extracted information revealed that: satellite masses range from few kg to 7821 kg of EnviSat; 80% of the missions are in SSO, near SSO, polar or near-polar orbits; altitude ranges from almost 400 to 1450 km and inclination between 20 and 100°.

Based on the main conclusions of this survey, the region defined by the SSO orbits between 350 and 850 km seems to be the most interesting for debris remediation and mitigation. The propulsion metrics retrieved considering SSO orbits allow designing a hybrid propulsion system suitable for the majority of LEO missions.
