Spot the spoof

Watch a vehicle’s reported position get pulled away by a spoofer, and see which checks catch it first.

TRACKING

Diagram of a true position track and a spoofed solution that peels away from it after a spoofer captures the receiver, with a detection point and a small chart of position offset crossing a threshold.

Simulated, with illustrative figures. Runs in your browser; nothing is uploaded.

Assumptions behind the figures
  • Speed check flags a reported speed above 18 m/s (true speed 15 m/s)
  • IMU check flags an offset above 5 m plus 0.1 m for every second elapsed
  • Power check flags a rise of 3 dB or more over the real signals
  • The spoofer takes over at 30 s

HOW IT WORKS

Capture, drag, detect

  1. Capture

    The spoofer matches the real signals, then slowly overpowers them.

  2. Drag

    It walks the reported position away, often too slowly to notice.

  3. Detect

    Independent checks such as speed limits, inertial sensors and signal power flag the mismatch.

TRY THIS

Things to try

  • Turn off every check and see how far the position drifts
  • Slow the drift and see which check still catches it
  • Raise the spoofer’s power and watch the power alarm
  • Compare detection time with and without the IMU
