Navigating in a GPS challenged environment
GPS and other Global Navigation Satellite Systems (GNSS) have become a critical component in determining your location and helping you navigate. However what are your options if access to GNSS is not possible?
Getting the trusted map or chart out may be one option – if you are human (or a smart machine), can read a map and have features around you that you can identify. This presentation will explore two other options that have been examined by QinetiQ.
The first is a modern version of navigating by the stars. This exploits the fact each star has its own celestial spectral fingerprint. Once the star is identified a navigational position can be derived employing the well-known single star method using celestial co-ordinates, altitude and azimuth and time of observation.
The second is a multi-spectral approach that exploits the availability of manmade radio frequency signals of opportunity. If you have a data-base of emitters with characteristics that you can identify and a known locations then position can be identified by direction finding and locating techniques.

Dr Mark O'Dell and Dr Anil Shukla
Technical Manager, QinetiQ Fellow - QinetiQ
Mark O’Dell is an experienced Technical Manager who leads the Celestial Navigation capability within QinetiQ’s Secure Navigation business.
He, and his team, have developed a novel approach to Celestial Navigation which is to be granted a European patent. This has received considerable interest by the Defence community as a possible alternative to global navigation satellite systems.
Mark was formerly a research scientist in the field of astronomy and prior to that a serving officer in the Royal Navy (Fleet Air Arm). He is a Fellow of the Royal Astronomical Society.
Dr Anil Shukla (FIET) is a QinetiQ Fellow in radio systems, RF technologies, propagation and spectrum regulation. He is the chair of the IET Antennas and Propagation Professional Network and Sub-editor of the IET Antennas and Propagation Journal.
Anil’s expertise ranges from medium-wave systems to mm-waves systems and his current research interests include: “Navigation using RF Signals of Opportunity”, “Operating Radio Systems in Difficult Environments“, “Physical Layer Security and Resilience”, and “Dynamic spectrum access / Intelligent Radios”.
