| Abstract:
Minor bodies show great variability in shape and surface morphological features. Since in the proximity of these bodies the dynamic is highly non-linear, communication windows with Earth could not be sufficient to navigate around them. Moreover, there is a growing demand for the reduction of costs deriving from ground-stations operations. As a result, the need for spacecraft with autonomous navigation capabilities both in far and close ranges. The most promising navigation technique is the optical one which allows the estimation of state information by exploiting optical observables extracted from images. To assess the robustness of optical navigation methods, it is required to perform tests on a variety of body shapes and with different surface morphological features. The importance of these tests arises from the shape and surface morphology estimation errors of ground-based estimation techniques. In this work, a procedural minor body generator tool implemented with an open-source 3D computer graphics software is described. The starting point of the tool is the three-dimensional mesh of a generic minor body which is procedurally modified by introducing craters, boulders, and surface roughness to obtain a photorealistic model in a real-looking environment. Two families of models can be generated by default: rocky ones, characterized by a large number of different-sized boulders, and cometary ones characterized by the typical morphology of comets, consisting of alternating rough and smooth regions, with the presence of small boulders.
