Abstract Recent advances in Artificial Intelligence (AI), sensing and computing technologies
have led to the development of new promising concept for the safe and efficient operation of …

As defined by ESA, space situational awareness (SSA) is the understanding and maintained
awareness of the Earth orbital population, the space environment and possible threats to …

The possibilities to observe and interact with any given spacecraft are naturally limited
compared to groundbased systems due to a number of factors. These include but are not …

One of the key requirements of a satellite cluster is to maintain formation flight among its
physically distinct elements while at the same time being capable of collision avoidance …

Abstract Space Situational Awareness (SSA) is key to ensure Space Safety and
Sustainability. In order to better understand the challenges of an increasingly congested …

Current state of the art in Space Traffic Management (STM) relies on a handful of providers
for surveillance and collision prediction, and manual coordination between operators …

The paper deals with the problem of time-optimal spacecraft reorientation maneuvers by
means of reaction wheels, with boundary and path constraints. When searching for solutions …

For a few years now, CNES has been developing ASTERIA, an on-board autonomy concept
combining autonomous station-keeping and collision risks management for Low Earth Orbit …

In the last decades, heuristic techniques have become established as suitable approaches
for solving optimal control problems. Unlike deterministic methods, they do not suffer from …

Multistage launch vehicles are commonly employed to place spacecraft and satellites in
their operational orbits. If the rocket characteristics are specified, the optimization of its …
