With GNSS Spoofing Attacks on the Rise, Resilience and Robustness Go Hand-in-Hand

Just five years ago, initiating a GNSS spoofing attack required not only high-priced equipment but university-level engineering expertise. Now, the technology and much of the software is freely available online, and bad actors with limited skill can use it. Faced with high-profile incidents such as the 2019 “Crop Circle” event in China, where ships entering the port of Shanghai were affected by spoofing at the mouth of the HuangPu river, and a similar event in Iran, we can see that the potential global impact is substantial.

Understanding the threat of spoofing can help you to mitigate

Our presentation* at ION GNSS+ 2020 detailed the technical aspects of our lab tests of GNSS receivers to see how they reacted to spoofing and meaconing attempts. This is the first time a detailed study of Read more…

Time is Everything With GNSS

Time is Everything With GNSSThe recent news of clock failures on both the European Union’s Galileo and IRNSS satellites (Indian Regional Navigation Satellite System) shows that launching and commissioning new satellite navigation constellations is not a simple business. The news, however, does make it worthwhile asking whether clock failures could have any implications for GNSS users — especially professional users such as in the surveying or GIS industries.

The short answer is that satellite clock failures should not directly impact any users of the Galileo or IRNSS satellites. In the event of all clocks (primary and backup) failing on a single GNSS satellite, the satellite becomes unusable. Read more…
