    GNSSReceiver ->> NMEADecoder: Parse satelliteID
    NMEADecoder ->> OSNMAValidator: Validate satelliteID authenticity

✅ Summary#

  • The satelliteID is captured and decoded from GNSS signals.
  • OSNMA validation ensures the identity and integrity of the source satellite.
  • The verified satelliteID is associated with captured photos for geospatial trust.
  • This supports use cases requiring verifiable positioning data.
