CPhys, FRIN,  Product Manager – GNSS Vulnerabilities 

New tests conducted by Spirent in a live sky environment demonstrate that some commercial GPS receiver models can be compromised by spoofing devices at 10m, 50m and 100m distance.

Find out how Spirent used live sky signals alongside simulation to demonstrate how commercial GPS receivers are vulnerable to spoofing attacks.

GPS Spoofing: New Live Sky Tests Confirm Receivers Are Vulnerable to Attack

No longer the preserve of powerful state actors, spoofing is a growing threat for GNSS-enabled equipment. Understanding how spoofing works and how to mitigate the potential impact of an attack is a key concern for developers of both commercial and military/government applications.

Growing reliance on GNSS technology means developers must address the threat of spoofing. Find out more.

As GNSS jamming and spoofing threats increase, new adaptive antenna systems aim to protect receivers from interference. Find out why adaptive antennas are needed, the challenges of testing adaptive antenna systems, and how adaptive antennas work.

Challenges of Testing Adaptive GNSS Antennas for Jamming and Spoofing Protection

With RF interference and spoofing attacks both on the rise, GNSS receiver developers must be able to simulate new threat sources in the lab.

A 5G network architecture typically requires primary reference time clocks (essentially GNSS receivers) to be installed near clusters of short-range base stations. Many clocks will be installed at street level in built-up areas, rather than on top of towers or tall buildings as has been the case with 4G. Multipath signals abound in such locations, while the narrow view of the sky often limits the number of line-of-sight satellite signals available. Both issues can severely affect a receiver’s ability to maintain accurate time, to the point where network quality of service can be seriously impacted.



Modern cellular networks need accurate time signals from GNSS satellites to keep transmission in sync. With Spirent’s help, NTT and Furuno have developed an algorithm for GNSS timing receivers that eliminates the effects of multipath, dramatically improvi
