Static Data Report (encrypted)

Introduction/Additional information:

The Static Data Message is used to send the equivalent information to AIS Message 5 but removes less essential data to compress message size.

Usage Notes

The FID 11 static data report shall be transmitted once every 6 minutes.
The data is matched by MMSI to the corresponding FID 10 message to provide additional information.

Version 0:

This is an RTCM compliant update of the FID 1 message listed in the Oct 2014 EAIS IDD. It also replaces the DAC 366, FI 57 Static Data Report from the same document.

Encrypted Situation Report (Message 26, Broadcast)

	Parameter	# of Bits	Description
	Parameter	# of Bits	Description
Standard Message Header	Message ID	6	Identifier for Message 26; always 26.
	Repeat Indicator	2	Indicates how many times a message has been repeated. 0 – 3; 0 = default; 3 = do not repeat any more. Set to zero (default).
	Source MMSI	30	MMSI number of source station. Varies according to the transmitter ID.
	Destination Indicator	1	0 = broadcast (no Destination ID field) 1 = Addressed (30 bit Destination ID field). Set to 1 (addressed).
	Binary Data Flag	1	0 = unstructured binary data (no Application Identifier bits used) 1 = binary data coded as defined by the 16-bit AI. Set to 1 (structured).
	Destination ID	0	MMSI number of destination station. Not Used.
	Spare	0	Not used.

Binary Data	Designated Area Code		10	Designated area code (DAC). Set to 366.
	Function Identifier		6	Function identifier. Set to (decimal) 39.
	Encrypted Payload	Version	3	Sequential number used to indicate the message version in steps of 1. 0 = test message = default; 1 – 7 = message version. Set to zero.
		Asset Name	90	Maximum 15 characters 6-bit ASCII as per ITU 1371. "@@@@@@@@@@@@@@@@" = not available = default. The Name should be as shown on the station radio license.
		Asset Type	10	Asset Type as per Appendix 1 of this VDL.
		DTE	1	Data terminal equipment (DTE) ready. 0 = available, 1 = not available = default.
		Encryption Bit Padding	24	Sufficient spare bits to ensure that the binary data is a multiple of 128 bits for block encryption. Set to 0.
	Checksum		16	16-bit CRC calculated as per EAIS Specification
Footer	Spare		4	Four extra bits to ensure the message ends on a byte boundary. Set to zero.
	Communications State Selector		1	0 = SOTDMA communication state follows 1 = ITDMA communication state follows
	Communications State		19	SOTDMA communication state (see ITU 1371-5 § 3.3.7.2.1, Annex 2), if communication state selector flag is set to 0, or ITDMA communication state (§ 3.3.7.3.2, Annex 2), if communication state selector flag is set to 1.
