Secure global navigation satellite systems

A mobile device configured for a secure a Satellite Positioning System (SPS), comprising:

• a communication interface configured to wirelessly communicate with a server;
• an SPS receiver configured to receive signals from satellites;
• at least one memory;
• and
• at least one processor coupled to the communication interface, the SPS receiver, and the at least one memory and configured to:
• receive, via the communication interface, an encrypted data from the server in a point-to-point communication session interface between the mobile device and the server;
• decrypt the encrypted data from the server, wherein the decrypted data comprises an assistance data for a geographical region of the mobile device, where the assistance data comprises navigation data and impairment status of satellites in the geographical region of the mobile device;
• and
• monitor signals received by the SPS receiver from a plurality of satellites obtained using the assistance data for the geographical region of the mobile device for position determination of the mobile device.
