Conference Paper
Full-text available
In 2015, the UN state members agreed on the "Transforming our world: the 2030 Agenda for Sustainable Development" document to drive the evolution of humanity in the close future. A great effort has been placed to understand how space missions and their data can support the goals fulfilment, both by private entities and public organisations like the...
Conference Paper
Full-text available
In the recent years, many large constellations have been announced to be deployed in Low Earth Orbit. Together with the existing space debris, the failed satellites from large constellations will pose a severe safety threat to the space environment. Driven by the strong demand to remove the failed satellites, D-Orbit and Politecnico di Milano, part...

This paper presents a system-level engineering approach for the preliminary coverage performance analysis and the design of a generic Global Navigation Satellite System (GNSS) constellation. This analysis accounts for both the coverage requirements and the robustness to transient or catastrophic failures of the constellation. The European GNSS, Gal...

This paper presents a system-level approach for preliminary analysis and design of a generic Global Navigation Satellite System (GNSS) constellation. This analysis accounts for both the coverage requirements and the robustness to transient or catastrophic failures of the constellation. The European GNSS, Galileo, is used as reference to prove the e...
Conference Paper
The optimisation of low-thrust orbital trajectories represents one of the classic non-linear constrained optimal control problems in space applications. Low-thrust systems are getting more involved in the design of new missions, such as for example the all-electric spacecraft, since they grant a greater final operational mass thanks to their high s...
Conference Paper
Full-text available
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...
Preprint

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 satellite's position vector and the direction of the navigation antenna line of sight, the surface generated by the intersection of the oblate ellipsoid and the assumed co...

Conference Paper
Full-text available
This paper introduces a system engineering tool for the optimisation of a generic GNSS constellation design by using Galileo as reference. The optimisation is performed by taking into account both the percentage of global coverage and the accuracy in the position determination. The tool executes the optimisation not only for nominal and ideal cases...

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.
