DETECTING SPOOFED GLOBAL NAVIGATION SATELLITE SYSTEM (GNSS) SIGNALS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240111061 titled 'DETECTING SPOOFED GLOBAL NAVIGATION SATELLITE SYSTEM (GNSS) SIGNALS
Simplified Explanation
The patent application describes a system where a user equipment (UE) can detect spoofed Global Navigation Satellite System (GNSS) signals and determine its position without relying on the spoofed signals.
- The UE receives a spoofing alert message indicating a spoofed GNSS condition.
- Based on the alert message, the UE determines the location of the spoofer broadcasting the spoofed signal.
- The UE then calculates its position without using the spoofed GNSS signal by comparing the spoofer's location with its own.
Potential Applications
This technology can be applied in areas where GNSS spoofing attacks are a concern, such as in critical infrastructure, defense systems, and autonomous vehicles.
Problems Solved
This technology addresses the issue of GNSS spoofing attacks that can lead to inaccurate positioning information, potentially causing safety hazards or security breaches.
Benefits
The system provides a way for UEs to detect and mitigate the effects of GNSS spoofing attacks, ensuring accurate and reliable positioning information for various applications.
Potential Commercial Applications
Commercial applications of this technology include secure navigation systems for ships, aircraft, and vehicles, as well as enhanced security measures for critical infrastructure and IoT devices.
Possible Prior Art
One possible prior art is the use of anti-spoofing techniques in military-grade GNSS receivers to prevent spoofing attacks.
Unanswered Questions
How does the system differentiate between legitimate and spoofed GNSS signals?
The system likely uses signal analysis and comparison techniques to identify anomalies in the received signals that indicate spoofing.
What measures are in place to prevent false positives in detecting spoofed GNSS signals?
The system may incorporate multiple layers of verification and validation to reduce the likelihood of incorrectly identifying legitimate signals as spoofed.
Original Abstract Submitted
in an aspect, a user equipment (ue) receives a spoofing alert message from either a server or an internet-of-things (iot) device that indicates whether a spoofed global navigation satellite system (gnss) condition is present. based on determining that the spoofing alert message indicates that a spoofed gnss condition is present, the ue determines, based on the spoofing alert message, a location of a spoofer broadcasting a spoofed gnss signal, determines, based on the location of the spoofer and a current location of the ue, that the ue is within a receiving area of the spoofed gnss signal, and determines a position of the ue without using the spoofed gnss signal.
