✅ Summary

• Satellite: Represents each GNSS satellite with ID, PRN, and validation info.
• GNSSValidator: Checks satellite trustworthiness using OSNMA.
• OSNMAHandler: Handles parsing and signature verification.

This structure supports navigation authentication workflows and geospatial data validation in the app.
