Podcast: the vulnerable state of global navigation satellite systems

They explore the importance of timing in navigation and the threat posed by the increase in spoofing and jamming in recent years. 

GNSSGlobal Navigation Satellite System (GNSS) … includes multiple systems like GPS, BeiDou and Galileo. The timing element is essential for various applications, including navigation and positioning.

Scott says spoofing incidents have increased globally, affecting aviation and other sectors. Spoofing misleads receivers, while jamming is an intentional denial of GPS access. This is possible because GPS signals are weak, making them vulnerable to manipulation. New Delhi is one location that has recently seen a spike in cases.

The conversation also covers non-hostile interference and the potential of new technologies like LEONGSO, or non-geostationary satellite orbit… PNT to enhance navigation resilience. To an extent, Scott agrees that multi-layered protection approaches can reduce reliance on GNSS. LEO PNT offers stronger signals and authentication capabilities. However, situational awareness remains crucial to detect jamming and spoofing. 

Non-hostile interference can also occur accidentally, due to faulty equipment, but what does our reliance on GPS and its recently discovered vulnerability mean for our societies?

Scott also discusses how the law deals with jamming and the role of governments in addressing these challenges.
