Chris Hargreaves is an R&D Engineer working for GRAD: the Research & Development Directorate for the General Lighthouse Authorities of the UK&Ireland. His work has mainly focused on developing resilient position-fixing systems for ships, able to accurately position a vessel in the absence of GNSS. He worked for many years on the UK's eLoran programme, but has recently concentrated more on integrity systems, and position-fixing using existing ship sensors such as Radar. He holds an MSC Degree in Navigation Technology from Nottingham University and an MSci degree in Mathematics and Physics from Durham University.

He received a Bachelor Degree in Aerospace Engineering and a Master in Communication and Computer Network Engineering (CCNE) from Politecnico di Torino, respectively in 2016 and 2020. He joined the DLR Institute of Communications and Navigation in 2020 where he currently works in the Multi-sensors Group of the Nautical System Department. His research focuses on signal processing and positioning algorithms for Medium Frequency R-Mode. He also works on sensor fusion for PNT systems, PNT integrity concepts and radio threats resiliency.

Martin Bransby is the Head of Navigation at Telespazio UK. He is accountable for delivering Telespazio’s research, innovation and product development programme in resilient PNT, focussing on a multi-layered, multi-systems approach to PNT provision, whilst setting and delivering the company’s PNT strategy and direction. Telespazio UK’s navigation strategy is currently focussed on maritime user terminals and services, timing, autonomy, and Moon exploration and space logistics. Martin is a Chartered Engineer, Fellow, Trustee and Council member of the Royal Institute of Navigation, and an Associate Fellow of the Nautical Institute. Martin is also the Chair of the UKSpace PNT Committee.

Triyan Arora is a researcher in navigation systems at Cranfield University. The main interests are time synchronisation and dissemination, maritime navigation and space navigation. The topic intended to be treated is on improving maritime vessel localisation.
