Casini, S. (author), Cervone, A. (author), Monna, G.L.E. (author), Visser, P.N.A.M. (author)This paper aims to investigate the capabilities of exploiting optical line-of-sight navigation using star trackers. First, a synthetic image simulator is developed to generate realistic images, which is later exploited to test the star tracker's performance. Then, generic considerations regarding attitude estimation are drawn, highlighting...journal article 2023

Casini, S. (author), Turan, E. (author), Cervone, A. (author), Monna, Bert (author), Visser, P.N.A.M. (author)This manuscript aims to present and evaluate the applicability of combining optical line-of-sight (LoS) navigation with crosslink radiometric navigation for deep-space cruising distributed space systems. To do so, a set of four distributed space systems architectures is presented, and for each of those, the applicability of the combination is...journal article 2023

Casini, S. (author), Cervone, A. (author), Monna, G.L.E. (author), Gill, E.K.A. (author)Line-of-Sight (LoS) navigation is an optical navigation technique that exploits the direction to visible celestial bodies, obtained from an onboard imaging system, to estimate the position and velocity of a spacecraft. The directions are fed to an estimation filter, where they are matched with the actual position of the observed bodies,...journal article 2023

Casini, S. (author), Fodde, Iosto (author), Monna, Bert (author), Cervone, A. (author), Gill, E.K.A. (author)The purpose of this work is to present a novel CubeSat architecture, aimed to explore Near Earth Asteroids. The fast growth in small satellite commercial-off-the-shelf technologies, which characterized the last decade of space industry, is exploited to design a 3U CubeSat able to provide a basic scientific return sufficient to improve the...journal article 2021

Casini, S. (author), Fodde, I. (author), Engelen, S. (author), Monna, Bert (author), Cervone, A. (author), Gill, E.K.A. (author)The aim of this paper is to assess the feasibility of using currently available commercial-off-the-shelf (COTS) small-satellites components in deep-space scenarios, studying their applicability and performance. To evaluate the performances, an asteroid fly-by mission is briefly introduced, but several of the selection criteria and ideas can be...conference paper 2020
