DEFINITIONS, ACRONYMS AND ABBREVIATIONS 3.1 Definitions For the purposes of this POEMS Document, the following definitions shall apply: 3.1.1 Calculated Item: A piece of information (e.g. the position
26、of a target) derived from the raw radar information through an intermediate processing such as transformation of co-ordinates, tracking, code conversion, etc. 3.1.2 Catalogue of Data Items: List of all the possible Data Items of each Data Category describing the Data Items by their reference, struct
27、ure, size and units (where applicable). 3.1.3 Data Block: Unit of information seen by the application as a discrete entity by its contents. A Data Block contains one or more Record(s) containing data of the same category. 3.1.4 Data Category: Classification of the data in order to permit inter alia
28、an easy identification. 3.1.5 Data Field: Physical implementation for the purpose of communication of a Data Item, it is associated with a unique Field Reference Number and is the smallest unit of transmitted information. 3.1.6 Data Item: The smallest unit of information in each Data Category. 3.1.7
29、 Measured Item: A piece of information (e.g. the position of a target) directly derived from the radar information and transmitted without any intermediate processing. 3.1.8 Mode S: An enhanced mode of secondary surveillance radar (SSR) which permits the interrogation of all SSR equipped aircraft an
30、d the addressed interrogation of suitably equipped aircraft and two-way exchange of digital data between such aircraft and the interrogator. 3.1.9 Record: A collection of transmitted Data Fields of the same category preceded by a Field Specification field, signalling the presence/absence of the vari
31、ous Data Fields 3.1.10 User Application Profile: The mechanism for assigning Data Items to Data Fields, and containing all necessary information which needs to be standardised for the successful encoding and decoding of the messages.

GENERAL PRINCIPLES 4.1 General The Data Link Function (DLF) provides the functionality to support the air/ground data link.The DL
40、F messages shall be exchanged between the Ground Data Link Processor (GDLP) and the DLF and shall be used to: manage the GDLP-DLF interface; manage the broadcast service; manage the GICB service; manage SVC/MSP downlink data flow; manage SVC/MSP uplink data flow. The Mode-S sensors shall use the fol
41、lowing co-ordinate system for category 18: Between the DLF function of the Mode-S sensors and the GDLP/Local User, local polar and Cartesian co-ordinates shall be used. The co-ordinates shall be a direct translation of the measured or coasted position of the track. The time stamp shall represent the
42、 time the aircraft has been (measured) or should have been (coasted) on that position. The speed will be expressed as groundspeed and heading, the heading will be with respect to geographical north at the position of the aircraft as valid at the moment of the time stamp. 4.1 User Application Profile
43、 and Data Blocks 4.2.1 A single User Application Profile (UAP) is defined and shall be used for Data Link Function messages. 4.2.2 Data Blocks containing Data Link Function messages shall have the following layout. CAT = 018 LEN Items of the first record FSPEC Items of the last record where: Data Ca
44、tegory (CAT) = 018, is a one-octet field indicating that the Data Block contains Data Link Function messages; Length Indicator (LEN) is a two-octet field indicating the total length in octets of the Data Block, including the CAT and LEN fields; FSPEC is the Field Specification.

46、4.3.2.1 Compulsory items represent commonly used data required by any application, they shall be implemented; 4.3.2.2 Optional items represent more specific data and their implementation shall be negotiated between users. 4.3.2.3 When Data Items are optional, they shall be either always transmitted
47、or conditionally transmitted. When conditionally transmitted, they shall be present in a Record only if certain conditions are met (e.g. availability of the data). 4.3.2.4 When transmitted, they shall always be in a Record with the corresponding FSPEC bits set to one; Mode S Datalink Function Messag
