What is a "Spoofing Gnss"? The Most Authoritative Explanation.

What is GNSS spoofing?

Spoofing is amalicious attempt to alter a user’s global navigation satellite system (GNSS) measurements, making their GNSS position unreliable. To mitigate spoofing, users must be alerted when there is a spoofing attempt.

How does GPS spoofing work?

This can involve a GPS spoofer or GPS spoofing technology, like an application, both of which alter data or these communication signals connected to a GPS. To do this, the transmitter needs to be near the GPS-enabled device you’re seeking to spoof. From there, it mimics the signal, tricking the GPS receiver into showing another location.

What is aim+ GNSS spoofing detection?

Advanced interference mitigation technologies, such as the Septentrio AIM+, use sophisticated signal-processing algorithms to mitigate jamming and flag spoofing. For spoofing detection, AIM+ checks for various anomalies in the GNSS signal, such as unusually high signal power.

Can a multi-antenna spoofer spoof a GNSS tracker?

This type of spooﬁng would likely be practical onlywith a cooperative victim, such as a ﬁshing boat whose crewwas intentionally spooﬁng its GNSS tracker in order to poachundetected in restricted waters. An expensive type of multi-antenna spoofer might transmitonly one spoofed signal from each antenna.
