About the event

In the first of two CW webinars on radio positioning, we look at methods for using radio signals to derive a position and consider how cellular signals in particular have been exploited.

When radio systems are designed specifically for positioning, the signals can be designed to make the most of the techniques used for location. Our first speaker will describe the most widely used radio positioning methods and see how well they can (or can’t!) cope with challenging environments.
Cellular signals are designed to cope with these challenging environments and have been used for positioning for a quarter of a century. Our second talk will explore how these signals have been used to assist and enable positioning.

This informal webinar will be chaired by Bob Cockshott from The KTN and CW Location SIG Champion.  Delegates will be encouraged to submit their own questions to draw on the speakers expertise and experiences.

21st July at 15:00 - 'Radio’s place in positioning – Tracking and Sleuthing’

The second online event in this series will feature a talk from Omnisense on 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 presentation will be from Inmarsat and will explore how aviation satellite communication data helped to identify the flight path of Malaysian Airlines flight MH370.

15:00

Welcome from our CEO, Simon Mead

15:05

Introduction from Chair Bob Cockshott, The KTN

15:05

Michael Jones, Roke Manor, 'Introduction to Emitter Geolocation'

Mike's talk will give an introduction to radio geolocation techniques, covering the traditional techniques of TDOA and AOA. The challenges of geolocation in urban and multipath environments will be discussed, and we will touch on some modern techniques using machine learning and augmented reality.

15:25

Dr Chris Marshall, 'Positioning with opportunistic cellular signals'

Cellular signals have many potential advantages for positioning use, as they are of high quality and reach deep indoors. Despite the cellular system being designed primarily for communication, rather than positioning, measurements of these signals can still give useful position information for many applications. Chris will discuss the limitations and possibilities, introduce experiences in the field, and draw out some lessons of general interest.
