Environmental aspects of passive de-orbiting devices

The technical objective of this study was to understand the net effect of using deorbiting technologies like sails or tethers over the future debris population around Earth. In principle, indeed, these attractive technologies will support the compliancy to post-mitigation disposal guidelines, for small missions. However, the increased cross section also increases the collision risk.

Feasibility of ultra low thrust transfers in L1, L2, Sun, Earth & Moon Systems

The number of spacecraft flying in highly nonlinear gravitational fields is largely increased during the last few decades, and probes orbiting in Lissajous or Halo orbits can be found around both the Lagrangian Points L1 and L2 of the Sun-Earth&Moon system.

Assessment of onboard DA state estimation for spacecraft relative navigation

The goal of this study is two-fold. First, to identify and develop a DA- based high-order filter for relative pose estimation. The application considered is the rendezvous with an uncooperative target, modelled after ESA's e.deorbit mission. Secondly, the DA algorithms are implemented on hardware mimicking the limited computational power available in space. The resulting implementation is tested in a processor in the loop (PIL) test-bench using the approach phase of the chaser to the uncooperative target to be estimated.
