Space debris monitoring is nowadays a priority for worldwide space agencies, due to the
serious threat that these objects present. More and more efforts have been made to extend …

This paper presents an overview on radar techniques for the observation of space debris in
low Earth orbits which were developed at FGAN in the frame of DARA and ESA/ESOC study …

Optical observations represent a passive method for space debris tracking and monitoring.
Although being constrained to limited time intervals, eg when the target is in sunlight and the …

The number of space objects monitored by USSPACECOM up to geostationary altitudes is
on the order of 10,000. These objects need to be larger than 10 to 30 cm in order to be …

Space debris are orbiting objects that represent a major threat for space operations. The
most used countermeasure to face this threat is, by far, collision avoidance, namely the set of …

One of the most important and valuable regions in space for telecommunications, Earth
observation and space science is the Geostationary Earth Orbit (GEO). The concept of the …

The constant increase in the number of space objects and debris orbiting the Earth poses
risks to satellites and other spacecraft, both in orbit and during the launching process …

The GRAVES system is a space surveillance system developed by the French Aerospace
Research establishment (ONERA) under contract from the French MoD. It consists of a …

As the amount of space debris orbiting the earth is continuously increasing, it is becoming
essential to monitor and predict the debris' trajectories in order to avoid collision that could …

Abstract Space debris is considered as a serious problem for operational space missions.
Many enabling space debris capturing and removal methods have been proposed in the …
