Chronos Technology Ltd successfully demonstrated GPS jamming-triggered camera technology in a formal GPS jammer test conducted at the Sennybridge Military Jamming Training Area in Lyedbrook, Wales at the end of August 2015, Gloucestershire, UK.
JammerCam™ GPS trigger camera technology Jammer was jointly developed by the University of Bath and the Department of Electrical and Electronic Engineering of Chronos Technology Ltd. The development is carried out within the framework of a project called “AJR”. Sensor Internet “feasibility study competition
These tests allow the JammerCam™ device to be tested in an outdoor environment, where a series of gps jammer are hidden in vehicles or convoys passing alone, including cars, trucks and containers. The camera sensor technology triggered by the jammer successfully identified and photographed the vehicle hosted by the jammer in all test cases and at all speeds and powers. Either way, the vehicle is placed in the center of the frame, so only one frame is needed, which greatly reduces the bandwidth required between the sensor and the web server.
The photo of the identified vehicle with the distractor will then be sent via the mobile network to a Web server where the photo is distributed as a hyperlink to the target email address. Then, within a few seconds after the camera clamps the jammer, the image can be recalled as actionable intelligence.
Professor Charles Curry, Managing Director of Chronos, explained: “In 2014, the University of Bath demonstrated the proof-of-concept system in the Sennybridge GPS jamming test. Then we had to overcome some major challenges, the most important of which was to fully automate the system in order to Only take pictures of vehicles hosting jammers. We know that even low-power cigarette lighter jammers will emit enough detectable interference to create bubbles around the vehicle, which makes it difficult to determine which vehicle with heavy traffic is carrying Jammers. Our two biggest discoveries were the identification of vehicles in the convoy containing jammers and the discovery and capture of a container.
