David Fleming manages the Time, Frequency and Acoustics Laboratory in the National Standards Authority of Ireland’ National Metrology Laboratory (NSAI NML). Holding a PhD. from the Technological University of Dublin, he has worked in the field of Metrology and Calibration in the NSAI NML for 15 years and has extensive experience in calibration, research, collaboration, mentoring, and project management.

Ricardo Verdeguer Moreno works as Product Line Manager at Spirent Communications providing Positioning, Navigation and Timing solutions for defence and space applications. He is an aerospace engineer, who graduated with honours from Cranfield University with an MSc in Autonomous Vehicle Dynamics and Control. His expertise encompasses market insights and technical proficiency in GNSS-based autonomous systems.

Ricardo will discuss key findings from analysis (co-authored by Miguel Ángel Gómez, Researcher at the Spanish National Institute of Aerospace Technology), illustrating how 3D simulation enables researchers and system developers to anticipate performance degradations, design robust mitigation strategies, and test resilience under controlled, repeatable conditions.

Ivan has extensive knowledge and experience in the area of Digital Signal Processing for Autonomous Systems which covers sensor technologies, perception, data and information fusion, and decision-making for Cyber-Physical Systems. Applications for these developments include vehicle health management, communication and surveillance solutions and, more recently, Position, Navigation and Timing (PNT) for aerospace and ground-based Autonomous and Intelligent Systems. Ivan is involved in and actively supporting the development and operation of several research facilities, such as the instrumentation of Muti-User Environment for Autonomous Vehicle Innovation (MUEAVI), Research and Innovation Timing Node, PNT simulation facility.
