The GPS is currently the most widely used and best known example of a Global Navigation Satellite System (GNSS) and as a system relies on GPS positioning to make its next move, it is important to understand GPS vulnerabilities and acknowledge the threats like jamming and spoofing. Jamming and spoofing equipment can be openly purchased online at a low cost. The Software Defined Radio (SDR) technology is also bringing the flexibility and cost efficiency to a whole new level. This research aims to explore this technology by asking the following research questions: Is there a suitable combination of waveform, power and amplitude to disrupt the GPS signal? Is GPS jamming equally easy to accomplish in software as it is in hardware? Is GPS spoofing easier to accomplish in software? The study consists of two tests: a GPS jamming test where focus is to realize what combination of waveform, power and amplitude is able to jam the GPS signal and a GPS spoofing test where a HackRF One is used to fool a mobile. The results from the jamming test have shown that GPS jamming is easy to accomplish using different combinations as GPS signals have low received signal power. The spoofing test proved that it is capable to spoof a mobile with a fairly inexpensive SDR setup and freely available software.
