Radio’s place in positioning – Tracking and Sleuthing

Brought to you by The Location Group, The Radio Technology Group

In the second of our series online events from the Radio Technology SIG working with the Location SIG we look at methods for using radio signals to derive a position.

Registration for this event is now closed.

About the event

In the second of our series of online events from the Radio Technology SIG working with the Location SIG we look at the application of some radio positioning techniques. In particular, our speakers look at solving tracking problems, using technologies from short range to very long range.

Our first speaker Gavan Duffy, CTO at Omnisense will talk about how short range radio technology may be used for high accuracy relative positioning and tracking for worker safety in the new world of Covid-19 social distancing.

Our second speaker Chris Ashton, Senior Director, Space Segment Resource Management at Inmarsat will explore how aviation satellite communication data helped to identify the flight path of Malaysian Airlines flight MH370.

This informal webinar will be chaired by Brian Collins, BCC Associates and CW Radio Technology SIG Champion.  Delegates will be encouraged to submit their own questions to draw on the speakers expertise and experiences.

Closing remarks & session ends


Chris Ashton - Senior Director, Space Segment Resource Management , Inmarsat

Chris has worked in the UK space industry for over 30 years specialising in communications payload design, operations and satellite traffic management. He is currently responsible for managing all radio signals passing through Inmarsat’s fleet of L-Band, S-Band and Ka-Band satellites. He was a member of the small team of Inmarsat Engineers that investigated the signals from the missing Malaysian airliner MH370 and developed and refined the techniques for extracting useful localisation data from the communication signal log files.

Gavan Duffy - CTO, Omnisense

Gavan Duffy is currently the acting CTO of Omnisense Limited who are a leading provider of real time remote positioning systems with diverse experience in exploitation of radio technologies in combination with innovative algorithms to enable high accuracy location of small low powered sensors with long battery life.

Initially educated as a Physicist at UMIST, he has subsequently worked in many sectors of IT including Expert Systems with Logica, derivatives trading systems with Bank Paribas, high performance computing with Digital Equipment Corporation. In 1996 he moved to Cambridge and worked as a Consultant with Scientific Generics (later renamed to Sagentia) where he also worked on diverse systems ranging from Financial modelling systems for Nationwide, Secure Random Number technology for the largest US Lottery provider, Web ticketing systems.

He also led the research activities in the fusion of biometrics with cryptography and is the principle inventor of several published patents, that were ultimately sold to the leading market provider of biometric encryption solutions.

Since 2007 he has been working in the field of biometrics as CTO of GenKey Limited which is a leading provider of biometric solutions in developing markets based on proprietary technologies that support cryptographic modes of biometric matching and high speed biometric matching technologies that exploit a biometric key material representation of biometrics to facilitate lightning fast biometric matching of the order of 50 million fingerprint matches per second on single core.

Whilst at Omnisense he has led the technical approach to development of a Social Distance monitoring product in conjunction with Equivital Limited who specialize in provisiong of wearable products that are focused on worker safety.
