Classification: CPC H  G | IPC G  H

Claim 0:
1. A method for validation of position, navigation, time (PNT) signals from a transmitter, the method comprising:
receiving, at a radio frequency receiver, a first sequence of messages, the messages comprising PNT data from a satellite and including orbital parameters of the satellite for satellite-based navigation for the radio frequency receiver;
extracting first data from the messages;
extracting second data from the messages, the second data being the PNT data spread in one or more of the messages of the first sequence;
validating an origin of the messages as an expected origin based on the first data; and
validating authenticity of the second data based on the first data; and
determine a geolocation, time, or navigation for the radio frequency receiver from the PNT data when the origin is validated and the second data is validated.
