In 1983, United States 40th President, Ronald Reagan, has made usage of Global Positioning System (GPS) available for civilian uses for free. Since then, we have been heavily reliant on GPS technology to help us determine precise and accurate location using our GPS receiver. One of the most common GPS receivers that almost everybody in Singapore has, is our smartphones. Many people, including you and me, uses mobile navigation applications, such as Google Maps and Waze, for directions. As those applications provide nearly instantaneous directions on the go, we tend to be reliant on those navigation applications for directions whether we are walking or driving to a specific location. However, in recent years, it is a worrying sight that GPS Spoofing is getting more and more common. As a result, your trusted navigation applications may inevitably show you inaccurate coordinates without you knowing that your GPS signal was hijacked by hackers. It poses a noteworthy danger if you rely on the navigation application, to navigate from one location to another in your car, as the hacker can possibly mislead you to a place that compromises your personal safety. All of these is just an example of what GPS Spoofing can do. GPS Anti-Spoofing, which is the mitigation/protection of GPS Spoofing, is considered as a newer field that is less explored. Thus, this project will be focusing more on the GPS Anti-Spoofing aspects. This project explores on the detection of GPS Spoofing via digital threats as opposed to RF-based threats. The project also explore how we can program a functional GPS Anti-Spoofing Detector with the help of Google Maps Platform (GMP), which provides us with accurate land information.
