Dr. Leonard Felicetti is an Associate Senior Lecturer in On-board Space System in Luleå University of Technology. He is also the teacher of the courses “Spacecraft Subsystems” and “Spacecraft Environment Interactions” of the Master Degree programs on Space Science and Technology of Luleå University of Technology.

He received his M.Sc. summa cum laude from Sapienza – University of Rome (Italy) in 2008 with a dissertation on the Attitude Dynamics and Control of a Cubesat implementing a Drag-Balance Instrument for measuring the Atmospheric Drag in Low Earth Orbit. In 2013, he received his Ph.D. on the “Dynamics, Guidance and Control of Multiple Platform Space Systems” and later, he was awarded a two-years post-doc grant at the Guidance and Navigation Lab of Sapienza -  University of Rome for a study contract on the Active Debris Removal by using Space Robotic Manipulators. In 2015, he was an Honorary Research Associate at University of Glasgow for a research on the Attitude and Orbit Control Strategies for Variable-Geometry Solar Sailing.

Research Interests

Leonard’s main research interests are in spacecraft orbital and attitude control systems, guidance, navigation and control of distributed space system, space robotics and multibody dynamics.

His current research explores the feasibility of a mission for space debris detection and surveillance by using formations of autonomous satellites.

During his Ph.D. and post-doc he had the chance to work in several topics all related to the space field, as:

- guidance and control of spacecraft formation flying with thrusters or electrostatic forces;

- attitude coordination strategies for satellite constellations and formation flying;

- tethered systems and space webs;

- on-orbit servicing and active debris removal missions;

- navigation (inertial and GNSS), estimation and filtering techniques;

- attitude dynamics of drag-balance satellites for upper atmosphere density measurements;

- space multibody dynamics and robotic systems;

- robust and reaction-less control techniques for space manipulators;

- attitude and orbit control of variable geometry solar sails;

- space mission analyses implementing advanced propulsion concepts, such as laser propulsion, inter-spacecraft electrostatic actions and solar sailing;

- space debris surveillance mission design.
