Dr Ed Bryant

With a BEng (Hons) degree course in Communication Engineering at Leeds, Ed received a NERC CASE award in 1991 to study for a PhD in Radio Tracking Systems at Sheffield University Radar Group. Closely working with the Sea Mammal Research Unit (SMRU) he spent the summers in the field in Norway tracking Harbour Seals (Phoca Vitulina). 

From 1995 to 1998 as a Research Fellow with SMRU he studied the effects of acoustic disturbance on seals. 

After a year of industrial experience developing electronic warfare receivers he returned to academia at Leeds University, where he was responsible for developing channel sounding systems for the measurement of radio wave reflections. These systems were then used to study the effect of radio wave multipath propagation on ISM band signals (2.4GHz) in industrial environments, and also the resilience of the proposed 'Galileo' satellite navigation system signal structure to multipath. 

He left Leeds as a Senior Research Fellow in 2002 to run his newly formed company ‘Wildtrack Telemetry Systems’.  In 2004 the first field prototypes of the Fastloc® GPS receiver were successfully trialled on Grey Seals in the North Sea.  The Fastloc® technology was licenced in 2005 and, now in its 3rd evolution, has been successfully deployed on thousands of marine animals around the world. 

In partnership with Dr Gary Brodin, a former colleague from Leeds University, Pathtrack Ltd was set up to develop the Fastloc® GPS receiver further and add enabling technologies such as UHF download capability, immersion sensing and solar charging. 

At present his role as a Director in Pathtrack includes responsibility for system, hardware and antenna design. 

Ed’s main areas of interest are: digital signal processing, receiver design, low power electronics, embedded programming and antennas
