Spacecraft design optimisation for demise and survivability
Mirko Trisolini, Hugh G. Lewis, Camilla Colombo
Among the mitigation measures introduced to cope with the space debris issue there is the de-orbiting of decommissioned satellites. Guidelines for re-entering objects call for a gr…
Demisability and survivability sensitivity to design-for-demise techniques
Mirko Trisolini, Hugh G. Lewis, Camilla Colombo
The paper is concerned with examining the effects that design-for-demise solutions can have not only on the demisability of components, but also on their survivability that is thei…
Impact probability computation of Near-Earth Objects using Monte Carlo Line Sampling and Subset Simulation
Matteo Romano, Matteo Losacco, Camilla Colombo +1
This work introduces two Monte Carlo (MC)-based sampling methods, known as line sampling and subset simulation, to improve the performance of standard MC analyses in the context of…
Stable attitude dynamics of planar helio-stable and drag-stable sails
Narcís Miguel, Camilla Colombo
In this paper the planar orbit and attitude dynamics of an uncontrolled spacecraft is studied, taking on-board a deorbiting device. Solar and drag sails with the same shape are con…
Coverage Area Determination for Conical Fields of View Considering an Oblate Earth
Marco Nugnes, Camilla Colombo, Massimo Tipaldi
This paper introduces a new analytical method for the determination of the coverage area modeling the Earth as an oblate ellipsoid of rotation. Starting from the knowledge of the s…
Extension of the King-Hele orbit contraction method for accurate, semi-analytical propagation of non-circular orbits
Stefan Frey, Camilla Colombo, Stijn Lemmens
Numerical integration of orbit trajectories for a large number of initial conditions and for long time spans is computationally expensive. Semi-analytical methods were developed to…
