The Static Data Payload format is intended to mirror Message 5 Ship Static and Voyage Related Data format contained in ITU-R M.1371-5. The table contained here is informational.
Implementers should refer back to ITU-R M.1371-[current revision] for most up to date bit usage and descriptions. The Static Data Payload prior to encryption without bit stuffing is 440 bits in length. Conforming to the AES Encryption scheme with a 128-bit cipher key, the encrypted part of the payload then effectively becomes 512 bits in length to create blocks of 128 bits. The FID 57 static data report shall be transmitted once every 6 minutes.
