Random Number Generation Based on Geodetic Datum

A method comprising:

• a. generating timing control information and geodetic datum information by a GNSS receiver;
• b. generating timing information by a timing update controller in response to the timing control information;
• c. generating PRN seed information by a PRN seed formatter in response to the geodetic datum information and the timing information;
• d. formatting PRN seed information by a PRN seed formatter in response to seed format information;
• and
• e. generating a PRN sequence by a PRN generator in response to the timing information and the PRN seed information.
