  GNSSMessage --> OSNMAValidator : provides data
  OSNMAValidator --> PublicKeyManager : uses for signature check

✅ Summary

• PublicKeyManager: Handles key management and signature verification for OSNMA.
• OSNMAValidator: Uses the public key to validate GNSS navigation messages.
• GNSSMessage: Supplies raw satellite message data to the validator.

This modular design supports secure, validated location data handling in offline or online modes.
