Write a state machine to parse the binary sync words. Do not search for ASCII strings (like $GPGGA ). Use a circular buffer and check CRC before processing.
This message is a GPS navigation data message (Message Type 2) that contains the following information: icd-gps-153 protocol
: The protocol uses structured binary packets. While specific documentation is often restricted to authorized personnel, it generally includes: : Identifies the start of a message packet. Message ID Write a state machine to parse the binary sync words
While the full protocol is controlled, common implementation examples (such as those used in timing systems) utilize specific message subsets: Safran - Navigation & Timing Current Status (Message 5040): This message is a GPS navigation data message
If "153" was a typo for "200," this is the fundamental protocol for the Global Positioning System. It is the document that defines the "L1" and "L2" carrier frequencies, the C/A (Coarse/Acquisition) code, and the P(Y) (Precise) code.
