Oral presentation at the conference
It is well known that orbital debris about Earth impose increasingly stringent restrictions on the operation and commissioning of both current and future space applications. These orbital debris, which are becoming ever so prevalent, can literally destroy a satellite. Even particles of diminutive stature can result in disastrous ramifications. Many of these endangered satellites, of which...

Oral presentation at the conference
The continuous growth of the population of objects in Low Earth Orbit (LEO) has caused an increase of the conjunctions between active satellites and other objects, either space debris or other satellites. It is mandatory to evaluate the risk these conjunctions pose, and to design the corresponding collision avoidance maneuvers if necessary. Since several maneuvers are to be performed in the...

The risk reduction measures required for the reentry of a spacecraft at its end of life are regulated in Europe by requirements documented in Space Agencies’ instructions and guidelines. In particular, according to the French law, “the operator responsible of a spacecraft controlled reentry shall identify and compute the impact zones of the spacecraft and its fragments for all controlled...

Oral presentation at the conference
The ever increasing number of objects in the near Earth region has been causing growing concerns about the space environment and accordingly about the safety of future space missions. Since most of orbital debris stay in the orbit for years, even a single collision between space objects could seriously increase the debris population, making further collisions more likely.

The paper describes the work performed and results achieved by LuxSpace for the ESA-supported DGNC project.
DGNC stands for Dragsail GNC. It is a project aiming at identifying the best GNC solution to be proposed for satellite (debris) deorbiting thanks to Dragsails.
The proposed and investigated GNC options are : (1) no attitude control, (2a) active attitude control constantly maximizing...

COBRA is a contactless concept for de-tumbling and controlling the attitude of a target space debris object that exploits the torques generated on the target by the plume impingement of a thruster facing the target to impart torques on the target. The control strategy for de-tumbling is based on a switching strategy for the de-tumbling thruster and a pointing strategy for aiming the...
