VHF air-ground and air-air Digital Link (VDL) Mode 4 radio equipment - Technical characteristics and methods of measurement for aeronautical mobile (airborne) equipment - Part 1: Physical layer

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 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 118,000 MHz to 136,975 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 should note that in future the tuning range for the transmitter may also cover any 25 kHz channel from 112,000 MHz to 117,975 MHz and the receiver(s) may cover any 25 kHz channel from 108,000 MHz to 117,975 MHz. The present document applies to "aeronautical mobile (airborne and in some cases ground vehicles)" equipment which will hereinafter be referred to as "mobile" equipment. The scope of the present document is limited to mobile stations. The equivalent specification for ground stations is EN 301 842 [10]. The VDL Mode 4 system provides digital communication exchanges between aircraft and ground-based systems and
other aircraft supporting surveillance and communication 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) capabilities;
- 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 as 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 includes:
- clause 2 provides references to relevant documents;
- clause 3 provides general definitions, abbreviations and symbols used;
- clause 4 provides a general description and architecture of VDL Mode 4;
- clause 5 provides functional specifications applicable to the physical layer including transmitter/receiver
requirements and the modulation scheme;
- clause 6 provides VDL Mode 4 equipment requirements;
- clause 7 provides general design requirements;
- clause 8 provides environmental test requirements;
- clause 9 provides detailed test procedures for the physical layer;
- clause 10 provides installed equipment requirements;
- annex A provides a detailed cross-reference to the relevant requirements contained in reference [1];
- annex B provides an assessment of VDL Mode 4 Link Budget;
- annex C provides a Bibliography;
- a document history.
The full physical layer tests are provided which correspond closely to the standard set of tests used for other VDL systems. NOTE: Flight tests are defined in EN 302 842-2 [7].

Pričujoči dokument velja za naslednje tipe radijske opreme:
- zelo visokofrekvenčna (VHF) digitalna povezava (VDL), 4. način, aeronavtičnih mobilnih (zračnih) radijskih oddajnikov, oddajnikov-prejemnikov in prejemnikov za komunikacije zrak-tla in zrak-zrak, ki deluje v pasu VHF z uporabo modulacije frekvenčnega premičnega kodiranja prek filtra Gaussian (GFSK) z razmikom 25 kHz med kanali in zmožna uravnavanja na kateri koli izmed kanalov 25 kHz od 118.000 MHz do 136.975 MHz, kot je opredeljeno v SARPs ICAO za VDL [2]. Pričujoči dokument zagotavlja 1. del tehničnih specifikacij. Pričujoči dokument zagotavlja, da bo oprema, ki jo certificira, združljiva z ustreznimi SARPs ICAO za VDL [2] in tehničnim priročnikom ICAO za VDL4.
Proizvajalci morajo biti pozorni, da razpon uravnavanja za oddajnik lahko v prihodnje zajema kateri koli 25 kHz kanal od 112.000 MHz do 117.975 MHz ter za prejemnike kateri koli 25 kHz kanal od 108.000 MHz do 117.975 MHz. Pričujoči dokument velja za »aeronavtično mobilno (za zračna vozila in v nekaterih primerih talna vozila)« opremo, v nadaljevanju »mobilna« oprema. Področje uporabe pričujočega dokumenta je omejeno na mobilne postaje. Ustrezna specifikacija za talne postaje je v EN 301.842 [10]. Sistem VDL, 4. način, zagotavlja izmenjavo digitalne komunikacije med zračnim plovilom in talnimi sistemi ter drugim zračnim plovilom, ki podpira uporabo nadzora in komunikacije. Podporni načini komunikacije vključujejo:
- oddajanje in komunikacijo tipa točka-točka;
- storitve oddajanja, vključno z zmožnostmi samodejnega odvisnega nadzora - oddajanje (ADS-B), storitve prometnih informacij - oddajanje (TIS-B) in storitve informacij o letih – oddajanje (FIS-B);
