3.1 Definitions

For the purposes of this Eurocontrol Standard Document, the followingdefinitions shall apply:

3.1.1

Calculated Item:

A piece of information (e.g. the position of a target) derivedfrom the raw radar information through an intermediateprocessing such as transformation of coordinates,tracking, code conversion, etc.

List of all the possible Data Items of each Data Categorydescribing the Data Items by their reference, structure,size and units (where applicable).

Unit of information seen by the application as a discreteentity by its contents. A Data Block contains one or moreRecord(s) containing data of the same category.

Classification of the data in order to permit inter alia aneasy identification.

Physical implementation for the purpose of communicationof a Data Item, it is associated with a unique FieldReference Number and is the smallest unit of transmittedinformation.

The smallest unit of information in each Data Category.A piece of information (e.g. the position of a target) directlyderived from the radar information and transmitted withoutany intermediate processing.

A collection of transmitted Data Fields of the samecategory preceeded by a Field Specification field,signalling the presence/absence of the various Data FieldsThe mechanism for assigning Data Items to Data Fields,and containing all necessary information which needs tobe standardised for the successful encoding and decodingof the messages.
