ETSI ETSI EN 302 842-1 V1.3.1 (2015-04) 7 Introduction The present document states the technical specifications for Very High Frequency (VHF) Digital Link (VDL) Mode 4 aeronautical mobile (airborne) radio transmitters, transceiv
39、ers 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 2. The
40、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 assumption
41、 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 may be tested in accordance with the methods of
42、measurement specified in the present document or a documented alternative approved by the certifying authority. ETSI ETSI EN 302 842-1 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 mobi
43、le (airborne) radio transmitters, transceivers 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 136,9
44、75 MHz as defined in ICAO VDL SARPs 2. The present technical document provides part 1 of the 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 shoul
45、d note that in future the tuning range for the transmitter and receiver may cover any 25 kHz channel from 108,000 MHz to 111,975 MHz. The present document applies to “aeronautical mobile (airborne and in some cases ground vehicles)“ equipment which will hereinafter be referred to as “mobile“ equipme
46、nt. The scope of the present document is limited to mobile stations. The equivalent specification for ground stations is ETSI EN 301 842 i.7. The VDL Mode 4 system provides digital communication exchanges between aircraft and ground-based systems and other aircraft supporting surveillance and commun
47、ication applications. The supported modes of communication include: broadcast and point-to-point communication; broadcast services including Automatic Dependent Surveillance - Broadcast (ADS-B), Traffic Information Service - Broadcast (TIS-B) and Flight Information Service - Broadcast (FIS-B) capabi
48、lities; air-air and ground-air services; operation without ground infrastructure. The present document is derived from the specifications: ICAO VDL4 Technical Manual 1 and ICAO VDL SARPs 2 produced under the auspices of the International Civil Aviation Organization (ICAO). Other relevant standards a
49、s defined in clause 2. It is envisaged that manufacturers may provide equipment supporting: broadcast services only; point-to-point services only; both broadcast and point-to-point services. The present document deals with tests of the physical layer necessary to support all types of equipment. 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 provides a general description and architectu
