35、ransceivers and receivers for air-ground and air-air communications operating in the VHF band, using Gaussian Filtered Frequency Shift Keying (GFSK) modulation with 25 kHz channel spacing and capable of tuning to any of the 25 kHz channels from 112,000 MHz to 136,975 MHz as defined in ICAO VDL SARPs
36、 2. The present document may be used to produce tests for the assessment of the performance of the equipment. The performance of the equipment submitted for type testing should be representative of the performance of the corresponding production model. The present document has been written on the as
37、sumption that: the type test measurements will be performed only once, in an accredited test laboratory and the measurements accepted by the various authorities in order to grant type approval; if equipment available on the market is required to be checked it will be tested in accordance with the me
38、thods of measurement specified in the present document or a documented alternative approved by the certifying authority; equipment comply with ETSI EN 302 842-1 5 and ETSI EN 302 842-2 6. NOTE: The present document has been produced with a view to maintaining consistency of numbering with the equiva
39、lent standard for ground equipment (ETSI EN 301 842 i.1). Where requirements are the same, they have been given the same number. Some new airborne requirements have been inserted between requirements that were sequential in ETSI EN 301 842 i.1. This has led to a non-standard form of numbering for ne
40、w requirements in some places. ETSI ETSI EN 302 842-4 V1.3.1 (2015-04) 8 1 Scope The present document applies to the following radio equipment types: Very High Frequency (VHF) Digital Link (VDL) Mode 4 aeronautical mobile (airborne) radio transmitters, transceivers and receivers for air-ground and a
41、ir-air communications operating in the VHF band, using Gaussian Filtered Frequency Shift Keying (GFSK) modulation with 25 kHz channel spacing and capable of tuning to any of the 25 kHz channels from 112,000 MHz to 136,975 MHz as defined in ICAO VDL SARPs 2. The present document provides part 4 of th
42、e technical specifications. The present document is designed to ensure that equipment certified to it will be compatible with the relevant ICAO VDL SARPs 2 and ICAO VDL4 Technical Manual 1. Manufacturers should note that in future the tuning range for the transmitter and receiver may also cover any
43、25 kHz channel from 108,000 MHz to 111,975 MHz. The present document applies to “aeronautical mobile (airborne and as applicable also ground vehicles)“ equipment which will hereinafter be referred to as “mobile“ equipment. The scope of the present document is limited to mobile stations. The equivale
44、nt specification for ground stations is ETSI EN 301 842 i.1. A description of the scope of the VDL Mode 4 system is provided in part 2 of ETSI EN 302 842-2 6, clause 1. ETSI EN 302 842-1 5 deals with tests of the physical layer, ETSI EN 302 842-2 6 deals with core link layer functionality and ETSI E
45、N 302 842-3 7 with additional broadcast functionality. The present document deals with tests of the datalink layer (DLS) and the link layer sufficient to support point-to-point functionality. Note that, as described in ETSI EN 302 842-2 6, a system supporting point-to-point functionality is required
46、 to conform to ETSI EN 302 842-1 5, ETSI EN 302 842-2 6 and the specification in the present document. The present document is organized as follows: clause 2 provides references to relevant documents; clause 3 provides general definitions, abbreviations and symbols used; clause 4 describes the VDL M
47、ode 4 mobile station point-to-point functions; clause 5 provides performance specifications for the VDL Mode 4 mobile station; clause 6 provides general design requirements; clause 7 provides protocol tests for the point-to-point functions of the system; annex A provides a detailed cross-reference t
48、o the relevant requirements contained in ICAO VDL4 Technical Manual 1. Note that the system can support a very wide range of functions. It is not practical to provide specific tests for all aspects of functionality. The approach used is to provide detailed tests for the core point-to-point functiona
49、lity and to provide tests of those remaining requirements which, if wrongly implemented, could cause a deterioration in the service offered by other VDL Mode 4 stations.
