To rapidly model the gravity field near elongated asteroids, an intelligent inversion method
using Hopfield neural networks (HNNs) is proposed to estimate on-orbit simplified model …

The exploration of celestial bodies such as the Moon, Mars, or even smaller ones such as
comets and asteroids, is the next frontier of space exploration. One of the most interesting …

Small bodies environment is usually difficult to be modelled for a number of reasons. Among
the others, the uncertainty associated to the non-uniform gravitational field requires in-situ …

This work investigates the potentialities of multispectral imaging data fusion for relative
navigation, mapping and dynamical characterization of an unknown celestial body. A vision …

Relative navigation methods are a critical enabling technology for the next generation of
autonomous spacecraft conducting close proximity operations. This is especially true for …

Future science and exploration missions will implement innovative mission concepts to
embark on daring endeavors exploiting cooperating intelligent systems. The concept of …
