Autonomous spacecraft proximity operations represent a key enabler for future mission architectures such as in-orbit servicing, active debris removal, objects' inspection, and in-orbit assembly. This work addresses safety concepts for the relative trajectory guidance design applicable to challenging proximity operations in the close-range domain. T...
In the framework of Active Debris Removal (ADR) missions employing rigid capture mechanism, the rotational state of the target object greatly influences the feasibility, safety and cost of the capture operations. In this work, the impingement with thruster’s plume gases is studied as a strategy to control the target tumbling motion and aid the fina...
The paper describes the design and modelling of an on-orbit mission experiment for testing a novel engine technology in Space. The goal is to assess the novel engine thrust profile through an on-orbit reverse engineering approach. The simulation tool developed at Politecnico di Milano is initially designed to propagate the free attitude dynamics of...
Large constellations' deployment in low Earth orbit will drastically change the space environment and economy in the upcoming decades. The sustainability of the orbital environment in the long term needs to be accounted when implementing the large constellations projects. In fact, failures among the large constellations' assets can critically endan...
The potentialities of In-Orbit Servicing (IOS) to extend the operational life of satellites and the need to implement Active Debris Removal (ADR) to effectively tackle the space debris problem are well known among the space community. Research on technical solutions to enable this class of missions is thriving, also pushed by the development of new...
The semi-analytical treatment of spacecraft's perturbed orbits can be used to interpret and evaluate efficiently its orbit evolution. The present study proposes a semi-analytical methodology to design continuous low thrust multi-revolutions manoeuvres in the mean orbital elements phase space introducing an artificial perturbation formulated as dist...
Space benefits mankind through the services it provides to Earth. Future space activities progress thanks to space transfer and are safeguarded by space situation awareness. Natural orbit perturbations are responsible for the trajectory divergence from the nominal two-body problem, increasing the requirements for orbit control; whereas, in space situation awareness, they influence the orbit evolution of space debris that could cause hazard to operational spacecraft and near Earth objects that may intersect the Earth. However, this project proposes to leverage the dynamics of natural orbit perturbations to significantly reduce current extreme high mission cost and create new opportunities for space exploration and exploitation. The COMPASS project will bridge over the disciplines of orbital dynamics, dynamical systems theory, optimisation and space mission design by developing novel techniques for orbit manoeuvring by “surfing” through orbit perturbations. The use of semi-analytical techniques and tools of dynamical systems theory will lay the foundation for a new understanding of the dynamics of orbit perturbations. We will develop an optimiser that progressively explores the phase space and, though spacecraft parameters and propulsion manoeuvres, governs the effect of perturbations to reach the desired orbit. It is the ambition of COMPASS to radically change the current space mission design philosophy: from counteracting disturbances, to exploiting natural and artificial perturbations. COMPASS will benefit extensive international, including the ESA, NASA, JAXA, CNES, and ASI. Indeed, the proposed idea of optimal navigation through orbit perturbations will address various major engineering challenges in space situation awareness, for application to space debris evolution and mitigation, missions to asteroids for their detection, exploration and deflection, and in space transfers, for perturbation-enhanced trajectory design.
