Tutors

Claudia Fiorentino

Course Director

Claudia Anita Maria Fiorentino started her career in the space sector joining Alenia Spazio spa (ALS now Thales Alenia Space Italia) where she has held different positions in the field of Satellite AIV/AIT working 12 years in several GEO and LEO TLC satellite projects (SICRAL, Globalstar, ARTEMIS, Italsat FM2), and LOE OE projects such as Radarsat-2 and PRIMA, the TAS “Common Platform” for LEO Earth Observation programmes. She joined the Italian Space Agency (ASI) in 2006 where she has been involved in the Cosmo-SkyMed integrated ASI/It-MoD Programme Office as E2E System Verification Manager of the first generation and then Mission Manager of the Cosmo-SkyMed Second Generation Programme. At ESA since 2017 as Senior Satellite System Development Engineer in the Directorate of Connectivity and Secure Communications (CSC), she is also currently the CSC Directorate Security Officer.

Martina Angelone

Course Director

Martina is the implementation manager of the EURIALO project of the Connectivity and Secure Communications (CSC) directorate at the European Space Agency (ESA), aiming at designing and demonstrating the first satellite-based independent aviation surveillance system.

She also covers the role of system engineer of the Iris programme where, since 2018, she has been responsible for all the system aspects concerning Iris project implementation, targeting the development of a satellite-based communication system for Air Traffic Management (ATM) and the design of its long-term evolution.  

Martina joined ESA in 2010 in the Communication systems and techniques section of the RF Payload system division, Technology, Engineering and Quality Directorate where for more than 8 years she has been responsible of many Advanced Research in Telecommunications Systems (ARTES) projects, focusing on high throughput satellite systems end-to-end performance, successfully developing technologies to improve Satellite Communications and contributing to the related standards.  

Martina received her M.S. degree, in Telecommunication Engineering from the University of Pisa, Italy, in 2008. Before joining ESA, she worked at M.B.I. s.r.l., a telecommunication company in Pisa, as a communication system engineer.  

Daniele Dequal

Course Director

Daniele Dequal is System Engineer for the EuroQCI program of the Connectivity and Secure Communication Directorate (CSC) at the European Space Agency (ESA). 

Since 2013, Daniele has been active in the research field of satellite quantum communication, formerly at Padua University and subsequently as a researcher at the Italian Space Agency. During this 10 years of activity he participated in the first experimental demonstration of satellite-to-ground quantum communication, the first single photon transmission from MEO orbit and later from GNSS orbit, and to the development of the first Italian Quantum Key Distribution (QKD) receiver for satellite applications. 

In 2023, he joined ESA as a System Engineer working for the IRIS2 program first (Infrastructure for Resilience, Interconnectivity and Security by Satellite) and later SAGA (Security And cryptoGrAphic mission) and EuroQCI (European Quantum Communication Infrastructure) as a QKD expert.
