 Dr Dimitrios Panagiotakopoulos is currently the Head of Unmanned Aircraft Systems (UAS) Traffic Management (UTM) research at Cranfield University. He has been leading the design and development of the National Beyond Visual Line of Sight (BVLOS) Corridor that aims to build up the capabilities and evidence to enables BVLOS flights of UAS in non-segregated airspace in the UK. Leveraging the Digital Aviation Research and Technology Centre, high-end simulator facilities and digital twins and Cranfield Airport’ Digital Control Tower, the UTM research group has setup a unique live/virtual sandbox and UTM/UAM (Urban Air Mobility) ecosystem to address the challenges that ATM/UTM integration and UAM applications. This includes enabling next generation autonomous and clean vehicles, particularly those powered with hydrogen energy.

 Dr Panagiotakopoulos was previously Air traffic Management Systems Specialist at Air Navigations Solutions Limited at Gatwick Airport and as Systems Engineering Manager at NATS. At NATS he commissioned, multi-million pounds complex Air Traffic Management (ATM) Systems at UK Airports. This included the very first use of an X-band radar for windfarm mitigation in the UK. At Gatwick, he led the development of the Airports’ 10-year Capacity Enhancement Roadmap to optimise and improve operations and infrastructure to enable Air Traffic Movement growth, which identified Operational Improvements from SESAR and NextGen Programmes and coordinated the different Airport stakeholders, including Airlines, Ground Handlers, Air Traffic Control to implement these solutions.  He has been acted as Safety and Quality management expert, producing Safety Assurance documentation demonstrating compliance to relevant UK/EU standards for a number of projects, such as (i) the Asset Acquisition activity by Edinburgh Airport from the previous Service Provider to facilitate transition; (ii) the commissioning of Airport ATM systems, required to put them into operational service.

 Dr holds a PhD from Imperial College London on Satellite Navigation and Positioning Systems, with a thesis that developed innovative statistical algorithms to monitor and guarantee the integrity of GNSS-based position and navigation computations within safety-critical aircraft flight management systems. I was the first time Extreme Value Theory was introduced in an ATM-related field.
