spoofing resistance testing of the GPS receiver
Key Features

Key Features

We have developed this application for testing our GNSS spoofing detection system, as well as for researching potential attack scenarios. The application allows you to modify key parameters (such as power, pseudorange, Doppler, and navigation message content) for emulating controlled spoofing attacks.

Security and Operational Benefits:

  • Conduct comprehensive research in the field of spoofing detection and prevention methods;
  • Test the existing infrastructure for spoofing vulnerabilities
  • Evaluate the quality of our spoofing detection system.
  • Simulate a GPS L1 spoofer in synchronous and asynchronous modes for developing the corresponding protection methods and detecting potential vulnerabilities of the equipment to spoofing and jamming attacks;
  • Multiple instances of the App can be grouped into a cluster with a single control for simulating synchronous spoofing with multiple TX;
  • Supports conducted connection to the device under test for laboratory testing and radiated connection for field testing;
  • Synchronization accuracy with a live-sky signal that does not exceed 250 nanoseconds;
  • Capable of adding multiple impairments to the signals like timecoordinates shift, satellite’s relative power, pseudorangeDoppler offset, etc.;
  • Can add various types of jamming to the signal like wideband noise, continuous wave, etc.;
  • Utilizes genuine almanac and ephemeris data.
