Intelligent vehicles and smart devices could gain more accurate location awareness by ‘fusing’ Global Navigation Satellite Systems (GNSS) and WiFi signals – and a test for this is the focus of an Innovate UK project led by Spirent Communications and involving WMG at the University of Warwick.
The £694k ‘Enhanced Assured Location Simulator Leveraging WiFi and GNSS Sensor Fusion’ (ELWAG) project will seek to develop to test this pioneering hybrid WiFi and GNSS location system in a cost-effective, repeatable and safe environment – so that manufacturers can verify its performance.
Researchers at WMG, led by Dr Matthew Higgins, will play a significant role in the project. They will take physical layer measurements of both Wi-Fi and GNSS signals in Autonomous Vehicle scenarios, in and around the University of Warwick campus and the local urban road network.
These measurements will then assist in Spirent’s development of an RF propagation model that will overlay RF effects on their Wi-Fi Access Point simulator. WMG researchers will then perform RF validation and verification activities around the developed model, to provide a level of assurance on its performance.
Dr Matthew Higgins, Associate Professor in the Intelligent vehicles group at WMG, University of Warwick, commented: “The safety and functional assurance of future autonomous vehicles will be one of the many critical paths to large consumer adoption. Through this project, we will contribute towards providing innovative solutions to the challenges of using sensor fusion in this testing context.”
