Introduction
I am a motivated Aerospace Engineer interested primarily in Space Systems Engineering and Guidance, Navigation and Control. I am currently a PhD candidate at TU Delft in the Space System Engineering section. My main research area relates to navigation solutions for distributed space systems, with a special focus on visual-based navigation in debris removal scenarios. I graduated with a MSc in Space Engineering from TU Delft, and prior to that with a BSc in Aerospace Engineering cum Laude from the University of Padua. During my MSc I undertook a six months traineeship at ESTEC, in the Thermal Division. Concurrently with my thesis, I worked at ISISpace, in the SE team, on flight correlation. Until May 2018 I worked at Gmv on the validation of the GNC software for the PROBA-3 mission.

Article
Full-text available
The estimation of the relative pose of an inactive spacecraft by an active servicer spacecraft is a critical task for close-proximity operations, such as In-Orbit Servicing and Active Debris Removal. Among all the challenges, the lack of available space images of the inactive satellite makes the on-ground validation of current monocular camera-base...

Conference Paper
Full-text available
This paper introduces a novel framework which combines a Convolutional Neural Network (CNN) for feature detection with a Covariant Efficient Procrustes Perspective-n-Points (CEPPnP) solver and an Extended Kalman Filter (EKF) to enable robust monocular pose estimation for close-proximity operations around an uncooperative spacecraft. The relative po...
Conference Paper
Full-text available
This paper reports on a comparative assessment of Image Processing (IP) techniques for the relative pose estimation of uncooperative spacecraft with a monocular camera. Currently, keypoints-based algorithms suffer from partial occlusion of the target, as well as from the different illumination conditions between the required offline database and th...
Article
Full-text available
The relative pose estimation of an inactive target by an active servicer spacecraft is a critical task in the design of current and planned space missions, due to its relevance for close-proximity operations, i.e. the rendezvous with a space debris and/or in-orbit servicing. Pose estimation systems based solely on a monocular camera are recently be...
Conference Paper
This paper reports on the reconstruction of key orbital elements of the Earth's orbit around the Sun from a miniaturized temperature sensor onboard the Delfi-C 3 CubeSat, a novel approach never explored before to the best of our knowledge. Delfi-C 3 is a triple-unit CubeSat, developed by Delft University of Technology, which was launched on April 2...
Conference Paper
Full-text available
A COMSOL Multiphysics®-based analysis of an innovative thermal actuation system capable of overtaking the traditional electrostatic comb drive, nowadays used for actuating the shutter array of variable emittance radiators, has been conducted as to validate this technology for the future active thermal control of CubeSats operating in an harsh envir...
