scope:

NES 1024,1026, and 1028 cover the technical requirements for interfacing to current warship combat systems using the CSH or TWSH. For equipment that will interface to these systems the standards are Category 1, mandatory, but for systems and equipment relating only to new platforms the standards should be considered as Category 2.

This part of NES 1028 defines the rules and protocols to be observed by multiple Co-operating member systems of a total system to enable effective intercommunication by exchange of standard messages. The rules and protocols defined herein are mandatory, except where stated, unless prior approval for deviation has been obtained from all MOD authorities concerned.

The aspects defined in this Part are:

The use of Message Catalogue Numbers-Section 1.4.

The use of Message Type Numbers-Section 1.5.

The provision of Time Synchronization and the use of Time of Validity of data-Section 1.6.

The Management of Communications Status amongst member systems-Section 1.7.

The provision for Communication Services-Section 1.8.

The Message Priority Service-Section 1.9.

The Datagram Transfer Service-Section 1.10. 4.

The data standards within this NES are primarily intended for member systems which communicate using a digital communications system that is shared by all the member systems. However, the data standards may be equally applied to systems using dedicated point-to-point connections.
