Global Positioning Service (GPS) receivers enable our mobile phones, smart watches, computer networks and many more aspects of our day-to-day lives to operate, providing us with convenient, high-trust information about the time of day and our position on a map grid.
Yet GPS, or other global navigation satellite systems, are a service we often take for granted. The use of this information is now so embedded in our lives that it can be considered as a critical piece of infrastructure. When you consider military applications, the integrity of this position, navigation and timing information must be absolutely undeniable in an environment where its loss would affect not only mission effectiveness but could also threaten lives.
So what if that signal were to disappear? What if it was blocked or even deliberately tampered with so it offered incorrect positioning information?
In our paper “Protecting our critical infrastructure” we unpack what could cause outages, interruptions or alterations to the signal, the impacts of those and explore what could be done to make that signal more resilient.
