stands for Interface Control Document for GPS User Equipment (Non-Standard) for the Precise (P/Y) Code . While the number "153" is less famous than its civilian counterpart (ICD-GPS-200), it is arguably more critical for national security. Baud Rate Mismatch: The receiver might default to

1. Baud Rate Mismatch: The receiver might default to 9600 baud after a cold start, but the host expects 38400. Always implement an autobaud detection or read the receiver's configuration message first.
2. Endianness Confusion: ICD-GPS-153 uses little-endian byte order for multi-byte fields (unlike many network protocols which use big-endian). A 16-bit length of 0x1234 is stored as 0x34, 0x12 on the wire.
3. Ignoring the User Equivalent Range Error (UERE): The protocol provides integrity information. High UERE indicates jamming or poor geometry. Your host system must act on this; otherwise, you risk feeding bad position data to a fire control system.
