How GPSwise Works

GPSwise transforms aircraft into a distributed network of GPS interference sensors. By analyzing ADS-B position broadcasts from the OpenSky Network, we detect GNSS interference in real time across the globe.

Three-Step Process

  1. Aircraft as Sensors – Commercial aircraft continuously broadcast ADS-B signals containing position data derived from GPS.
  2. Data Collection – Data ingestion via crowd-sourced ADS-B sources (OpenSky Network) or customer-provided ADS-B data in private deployments.
  3. Interference Detection – Advanced algorithms analyze aircraft data to identify GPS interference including jamming and spoofing.

Spoofing Detection

Our algorithms detect sudden, unrealistic position jumps that indicate false GPS coordinates being injected into an aircraft's navigation system.

Jamming Detection

We monitor Navigation Integrity Category (NIC) degradation patterns to identify areas where GPS signals are being blocked or disrupted. Good NIC (7+) indicates reliable GPS; Average NIC (5–7) shows degraded signals; Poor NIC (0–5) suggests severe interference or jamming.
