The right response to jamming? Instead of using valuable human resources to field and operate expensive jamming detectors, why not use existing hardware and infrastructure, and let a computer watch for jammers as a preemptive action? The Colorado Center for Astrodynamics Research has been working towards this goal. Based on both previous and current research, the centre’s team has implemented the first J911 prototype. In this system, regular smartphones or cheap sensors report GNSS signal conditions to a central server that can then depict these measurements and provide for fast, easy jamming detection. The J911 system could be built on top of the Enhanced 9-1-1 or Advanced Mobile Location infrastructure, which are used for location reporting as a part of emergency calls in the USA and Europe. Since this infrastructure is already in place, J911 is implemented mostly in software, which allows for easy deployment, testing, and upgrades. This in turn significantly reduces the costs of development and operation compared to existing solutions, which all require fielding and dedicated devices. J911 enables governments to keep up with technology and provide the next level of public service and protection.
