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 3: Additional broadcast aspects

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 130 [i.2].
The present technical document provides part 3 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 [i.2] and ICAO VDL4 Technical Manual [i.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 [4], [5], [6] and [7].
A description of the scope of the VDL Mode 4 system is provided in part 2 of these technical specifications (see EN 302 842-2 [2], clause 1).
EN 302 842-1 [1] deals with tests of the physical layer. EN 302 842-2 [2] deals with tests of the link layer sufficient to support broadcast functionality including requirements and tests sufficient to recognize and respond to transmissions associated with point-to-point communication. The present document provides technical specifications for a VDL Mode 4 mobile transceiver supporting a full Automatic Dependent Surveillance-Broadcast (ADS-B) capability and, optionally, the additional functionality of either, or a combination of, the following services:
Traffic Information Service-Broadcast (TIS-B);
Flight Information Service-Broadcast (FIS-B);
GNSS Augmentation Service-Broadcast (GNS-B).
The TIS-B, FIS-B, or GNS-B reception processing functionality in the airborne equipment is expected to be provided by a TIS-B, FIS-B or GNS-B processor, which could be contained within the VDL Mode 4 transceiver, but could also be housed in a separate physical unit. Therefore to support TIS-B, FIS-B or GNS-B message reception, the minimum functionality demanded of a basic VDL Mode 4 airborne transceiver unit (i.e. one that does not have a TIS-B, FIS-B or GNS-B processor housed within it) is to pass to the TIS-B, FIS-B or GNS-B processor, all TIS-B, FIS-B or GNS-B messages received.
As the measured values of equipment performance may be a function of the method of measurement, standard test conditions and methods of test are recommended in the present document.

Radijska oprema za digitalno povezavo VHF (VDL) zrak-tla in zrak-zrak, 4. način - Tehnične karakteristike in merilne metode za aeronavtično mobilno (letalsko) opremo - 3. del: Dodatni vidiki v zvezi z radiodifuzijo

Ta dokument velja za naslednje vrste radijske opreme:
 zelo visokofrekvenčna (VHF) digitalna povezava (VDL), 4. način, aeronavtičnih mobilnih (zračnih) radijskih oddajnikov, oddajnikov in prejemnikov ter 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 uravnavati na kateri koli izmed kanalov 25 kHz od 118.000 MHz do 136.975 MHz, kot je opredeljeno v 130 SARPs ICAO za VDL [i.2].
Ta dokument zagotavlja 3. del tehničnih specifikacij.
Ta dokument zagotavlja, da bo oprema, ki jo certificira, združljiva z ustreznimi SARPs za ICAO VDL [i.2] in tehničnim priročnikom ICAO za VDL4 [i.1].
Proizvajalci morajo biti pozorni, da razpon uravnavanja za oddajnik lahko v prihodnje zajema kateri koli kanal 25 kHz od 112.000 MHz do 117.975 MHz in za prejemnike kateri koli kanal 25 kHz od 108.000 MHz do 117.975 MHz.
Ta dokument velja za »aeronavtično mobilno (za zračna vozila in v nekaterih primerih talna vozila)« opremo, v nadaljevanju »mobilna« oprema.
Področje uporabe tega dokumenta je omejeno na mobilne postaje. Ustrezna specifikacija za talne postaje je v EN 301 842 [4], [5], [6] in [7].
Opis področja uporabe sistemov VDL, 4. način, je naveden v 2. delu teh tehničnih specifikacij (glej EN 302.842-2 [2], točko 1).
EN 302.842-1 [1] obravnava preskuse fizične plasti. EN 302 842-2 [2] obravnava preskuse plasti povezave, zadostne za podporo oddajne funkcionalnosti, ter prav tako vključuje zahteve in preskuse zadostne za prepoznavo in odgovor na oddajanja, povezana s komunikacijo točka-točka. Ta dokument podaja tehnične specifikacije za mobilne oddajnike in sprejemnike VDL, 4. način, ki podpirajo zmožnosti popolnega samodejnega odvisnega nadzora oddajanja (ADS-B), in opcijsko, dodatne funkcionalnosti ali kombinacijo naslednjih storitev:
 storitev prometnih informacij - oddajanje (TIS-B);
 storitev informacij o letih - oddajanje (FIS-B);
 razširjene storitve informacij GNSS - oddajanje (GNS-B).
Za funkcionalnost obdelave sprejema TIS-B, FIS-B ali GNS-B v letalski opremi se pričakuje, da jo zagotavljajo procesorji TIS-B, FIS-B ali GNS-B, ki so lahko vgrajeni v oddajnik in sprejemnik VDL, 4. način, vendar so prav tako lahko vgrajeni v ločeni fizični enoti. Zato je za podporo sprejemanju sporočila TIS-B, FIS-B ali GNS-B minimalna zahtevana funkcionalnost osnovnih letalskih sprejemnih in oddajnih enot VDL, 4. način (tj. če procesor TIS-B, FIS-B ali GNS-B ni vgrajen) predati procesorjem TIS-B, FIS-B ali GNS-B vsa prejeta sporočila TIS-B, FIS-B ali GNS-B.
Ker so lahko merjene vrednosti delovanja opreme funkcija metode merjenja, so v tem dokumentu priporočeni standardni preskusni pogoji in preskusne metode.
Ta dokument je urejen:
 točka 2, ki se sklicuje na ustrezne dokumente;
 točka 3, ki podaja uporabljene splošne definicije, okrajšave in simbole;
 točka 4 opisuje funkcionalnosti mobilne postaje VDL, 4. način, za podporo ADS-B, TIS-B, FIS-B in GNS-B;
 točka 5 podaja delovne specifikacije mobilne postaje VDL, 4. način, za podporo storitev ADS-B, TIS-B, FIS-B in GNS-B;
 točka 6, ki podaja splošne zahteve za načrtovanje;
 točka 7 podaja preskuse protokola, ki poudarjajo funkcije sistema ADS-B, TIS-B, FIS-B in GNS-B;
 dodatek A, ki podaja podrobno sklicevanje na ustrezne zahteve, zajete v tehničnem priročniku ICAO VDL4 [i.1];
 dodatek B, ki podaja bibliografijo;
 zgodovina dokumenta.
Bodite pozorni na to, da lahko sistem podpira zelo širok razpon funkcij. Podajanje določenih preskusov za vse vidike funkcionalnosti ni praktično. Namen uporabljenega pristopa je podati podrobne preskuse za jedrno funkcionalnost za podporo ADS-S, FIS-B, TIS-B in GNS-B, osredotočenega na sistemske zahteve, ki lahko, če se narobe izvajajo, povzročijo poslabšanje storitev, ki jih ponujajo postaje VDL, 4. način.

ETSI ETSI EN 302 842-3 V1.3.1 (2011-09)6 Introduction The present document states the technical specifications for 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 [i.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 assumption 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 methods of measurement specified in the present document or a documented alternative approved by the certifying authority; • equipment comply with EN 302 842-1 [1] and EN 302 842-2 [2]. NOTE: The present document has been produced with a view to maintaining consistency of numbering with the equivalent standard for ground equipment (EN 301 842 [4], [5], [6] and [7]). 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 EN 301 842 [4], [5], [6] and [7]. This has led to a non-standard form of numbering for new requirements in some places. SIST EN 302 842-3 V1.3.1:2011



ETSI ETSI EN 302 842-3 V1.3.1 (2011-09)7 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 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 130 [i.2]. The present technical document provides part 3 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 [i.2] and ICAO VDL4 Technical Manual [i.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 [4], [5], [6] and [7]. A description of the scope of the VDL Mode 4 system is provided in part 2 of these technical specifications (see EN 302 842-2 [2], clause 1). EN 302 842-1 [1] deals with tests of the physical layer. EN 302 842-2 [2] deals with tests of the link layer sufficient to support broadcast functionality including requirements and tests sufficient to recognize and respond to transmissions associated with point-to-point communication. The present document provides technical specifications for a VDL Mode 4 mobile transceiver supporting a full Automatic Dependent Surveillance-Broadcast (ADS-B) capability and, optionally, the additional functionality of either, or a combination of, the following services: • Traffic Information Service-Broadcast (TIS-B); • Flight Information Service-Broadcast (FIS-B); • GNSS Augmentation Service-Broadcast (GNS-B). The TIS-B, FIS-B, or GNS-B reception processing functionality in the airborne equipment is expected to be provided by a TIS-B, FIS-B or GNS-B processor, which could be contained within the VDL Mode 4 transceiver, but could also be housed in a separate physical unit. Therefore to support TIS-B, FIS-B or GNS-B message reception, the minimum functionality demanded of a basic VDL Mode 4 airborne transceiver unit (i.e. one that does not have a TIS-B, FIS-B or GNS-B processor housed within it) is to pass to the TIS-B, FIS-B or GNS-B processor, all TIS-B, FIS-B or GNS-B messages received.
As the measured values of equipment performance may be a function of the method of measurement, standard test conditions and methods of test are recommended 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 Mode 4 mobile station functionality to support ADS-B, TIS-B, FIS-B and GNS-B; • clause 5 provides performance specifications for the VDL Mode 4 mobile station supporting ADS-B, TIS-B, FIS-B and GNS-B Services; • clause 6 provides general design requirements; SIST EN 302 842-3 V1.3.1:2011



ETSI ETSI EN 302 842-3 V1.3.1 (2011-09)8 • clause 7 provides protocol tests which emphasis the ADS-B, TIS-B, FIS-B and GNS-B functions of the system; • annex A provides a detailed cross-reference to the relevant requirements contained in ICAO VDL4 Technical Manual [i.1]; • annex B provides a Bibliography; • a document history. 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 functionality to support ADS-B, FIS-B, TIS-B and GNS-B focusing on the system requirements which, if wrongly implemented, could cause a deterioration in the service offered by other VDL Mode 4 stations. Mandating and Recommendation Phrases a) "Shall": - The use of the word "Shall" indicates a mandated criterion; i.e. compliance with the particular procedure or specification is mandatory and no alternative may be applied. b) "Should": - The use of the word "Should" (and phrases such as "It is recommended that.", etc.) indicates that though the procedure or criterion is regarded as the preferred option, alternative procedures, specifications or criteria may be applied, provided that the manufacturer, installer or tester can provide information or data to adequately support and justify the alternative. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
