Many scientific applications require the implementation of satellite formation-flying in various
orbits both around Earth and other planetary bodies. The design and guidance of these new …

This paper presents the solutions to the spacecraft relative trajectory reconfiguration
problem when a continuous thrust profile is used, and the reference orbit is circular. Given a …

Understanding of relative motion dynamics is essential for many spaceflight objectives, from
orbit determination to rendezvous. Although these dynamics are well understood in a …
