DETECTING SPOOFED GLOBAL NAVIGATION SATELLITE SYSTEM (GNSS) SIGNALS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18534325 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.

Potential Applications

This technology can be applied in:

  • Defense and military operations to detect and counteract spoofed GNSS signals.
  • Autonomous vehicles to ensure accurate positioning and navigation.

Problems Solved

This technology addresses the following issues:

  • Preventing unauthorized manipulation of GNSS signals.
  • Ensuring the reliability and accuracy of location-based services.

Benefits

The benefits of this technology include:

  • Enhanced security against GNSS spoofing attacks.
  • Improved trustworthiness of location data for critical applications.

Potential Commercial Applications

This technology has potential commercial applications in:

  • Navigation systems for aviation and maritime industries.
  • Location-based services for emergency response and public safety.

Possible Prior Art

One example of prior art in this field is the use of anti-spoofing techniques in military-grade GNSS receivers to detect and mitigate spoofing attacks.

Unanswered Questions

How does the system differentiate between legitimate and spoofed GNSS signals?

The system likely uses signal analysis and comparison with known patterns to identify spoofed signals.

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 false alerts.


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.
