A novel geometric guidance algorithm is proposed for spacecraft formation flying. The
controllability of the full relative motion is analyzed using Lie bracket theory. The fuel-optimal …

This paper presents a sampling-based spacecraft relative motion planning algorithm to
reconfigure a spacecraft from a given initial state to a desired final state, subject to …

The recent decades have witnessed a tremendous growth in the number of satellites and
debris in space, leading to an increasingly high risk of collision between space objects …

Space-based sensing is likely to increase in prevalence in the coming years, yet challenges
still exist from a sensor management perspective. To address this we use modelling …

The safety of future spaceflight depends on space surveillance and space traffic
management, as the density of objects in Earth orbit has reached a level that requires …

The growing space debris environment poses a significant threat to operational satellites
and the future of spaceflight. To assess the collision risk between space objects, often …

The EU SST programme evolved into a fully-fledged component of the European Union
Space Programme adopted on April 28, 2021, after it has been set up in 2016 on the basis …

This research introduces a novel Guidance, Navigation, and Control (GNC) algorithm for
spacecraft formation flying. The theoretical background of the proposed relative path planner …

Satellite operators are overwhelmed by proximity warnings published in conjunction
analysis reports. Historically proven, the vast majority are false warnings and can be safely …

Abstract Space traffic management is becoming increasingly more complex with the growing
number of maneoeuvring satellites particularly in low Earth Orbit (LEO) due to the race for …
