Radijska oprema za digitalno povezavo VHF 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 se uporablja za radijsko opremo naslednjih vrst:
• aeronavtične mobilne (letalske) radijske oddajnike, oddajnike-sprejemnike in sprejemnike za zelo visokofrekvenčno (VHF) digitalno povezavo (VDL) za komunikacije zrak-tla in zrak-zrak, 4. način, ki delujejo v pasu VHF z uporabo modulacije frekvenčnega premičnega kodiranja prek filtra Gaussian (GFSK) z razmikom 25 kHz med kanali in so zmožni uravnavati na katerem koli izmed kanalov 25 kHz od 112.000 MHz do 136.975 MHz, kot je opredeljeno v standardih in priporočenih praksah (SARP) [i.2] ICAO za digitalne povezave (VDL).
Ta dokument vsebuje 3. del tehničnih specifikacij.
Ta dokument zagotavlja, da bo oprema, ki bo certificirana v skladu z njim, združljiva z ustreznimi standardi (SARP) [i.2] ICAO za VDL in tehničnim priročnikom ICAO za VDL4 [i.1].
Proizvajalci naj bodo pozorni, da razpon uravnavanja za oddajnik in sprejemnik lahko v prihodnje zajema tudi kateri koli kanal 25 kHz od 108.000 MHz do 111.975 MHz.
Ta dokument se nanaša na »aeronavtično mobilno (letalska in v nekaterih primerih tudi kopenska vozila)« opremo, v nadaljnjem besedilu: »mobilna« oprema.
Področje uporabe tega dokumenta je omejeno na mobilne postaje. Enakovredna specifikacija za zemeljske postaje je ETSI EN 301 842 [i.7].
Opis področja uporabe sistema VDL, 4. način, je naveden v 2. delu teh tehničnih specifikacij (glej ETSI EN 302 842-2 [2], 1. točka).
ETSI EN 302 842-1 [1] obravnava preskuse fizične plasti. Standard ETSI EN 302 842-2 [2] zajema preskuse plasti povezav, ki zadostujejo za podporo radiodifuzijskih funkcij, vključno z zahtevami in preskusi, ki zadostujejo za prepoznavanje in odgovarjanje na prenose, povezane s komunikacijo točka-točka. Ta dokument vsebuje tehnične specifikacije za mobilni oddajnik-sprejemnik VDL, 4. način, ki podpira polni avtomatski odvisni nadzor – difuzija (ADS-B) in izbirno dodatne funkcije ene storitve ali kombinacije naslednjih storitev:
• difuzija nadzornih podatkov (TIS-B);
• difuzija informacij za letalstvo (FIS-B);
• storitev izboljšave GNSS – difuzija (GNS-B).
Pričakuje se, da funkcije storitev TIS-B, FIS-B ali GNS-B v opremi na letalu omogoča procesor TIS-B, FIS B ali GNS-B, ki je lahko znotraj sprejemnika-oddajnika VDL, 4. način, lahko pa se nahaja tudi v ločeni enoti. Za podporo sprejemanja sporočil TIS-B, FIS-B ali GNS-B je tako minimalna funkcionalnost, ki se zahteva od osnovne oddajno-sprejemne enote VDL, 4. način, na letalu (tj. enote, ki ne vsebuje procesorja TIS-B, FIS-B ali GNS-B), posredovanje vseh prejetih TIS-B, FIS-B ali GNS-B sporočil procesorju TIS-B, FIS-B ali GNS-B.
Ker so merjeni podatki zmogljivosti opreme lahko odvisni od merilnih metod, ta dokument priporoča standardne preskusne pogoje in metode.
Ta dokument je organiziran na naslednji način:
• točka 2 vsebuje sklice do ustreznih dokumentov;
• točka 3 vsebuje splošne opredelitve, kratice in simbole, ki se uporabljajo;
• točka 4 opisuje funkcije mobilne postaje VDL, 4. način, za podporo storitev ADS-B, TIS-B, FIS-B in GNS-B;
• točka 5 vsebuje specifikacije lastnosti mobilnih postaj VDL, 4. način, ki podpirajo storitve ADS-B, TIS-B, FIS-B in GNS-B;
• točka 6 vsebuje splošne zahteve projekta;
• točka 7 vsebuje preskuse protokolov s poudarkom na funkcijah ADS-B, TIS-B, FIS-B in GNS-B sistema;
• dodatek A vsebuje podrobne sklice do ustreznih zahtev, ki so vključene v tehnični priročnik ICAO za VDL4
[i.1];
• dodatek B vsebuje bibliografijo.
Upoštevati je treba, da lahko sistem podpira zelo širok nabor funkcij. Podajanje določenih preskusov za celoten nabor funkcij ni praktično. Tako so podani podrobni preskusi za osrednje funkcije za podporo storitev ADS-B, FIS-B, TIS-B in GNS-B, ki se osredotočajo na tiste zahteve sistema, ki lahko v primeru nepravilnega izvajanja povzročijo poslabšanje storitve, ki jo zagotavljajo druge postaje VDL, 4. način.

ETSI ETSI EN 302 842-3 V1.4.1 (2015-04)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 112,000 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 complies with ETSI EN 302 842-1 [1] and ETSI 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 (ETSI EN 301 842 [i.7] parts 1 to 4). 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.7] parts 1 to 4. This has led to a non-standard form of numbering for new requirements in some places. SIST EN 302 842-3 V1.4.1:2015
ETSI ETSI EN 302 842-3 V1.4.1 (2015-04)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 112,000 MHz to 136,975 MHz as defined in ICAO VDL SARPs [i.2]. The present 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 and the receiver may also 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" equipment.
The scope of the present document is limited to mobile stations. The equivalent specification for ground stations is ETSI EN 301 842 [i.7]. A description of the scope of the VDL Mode 4 system is provided in part 2 of these technical specifications (see ETSI EN 302 842-2 [2], clause 1). ETSI EN 302 842-1 [1] deals with tests of the physical layer. ETSI 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; • clause 7 provides protocol tests which emphasis the ADS-B, TIS-B, FIS-B and GNS-B functions of the system; SIST EN 302 842-3 V1.4.1:2015
ETSI ETSI EN 302 842-3 V1.4.1 (2015-04)8 • annex A provides a detailed cross-reference to the relevant requirements contained in ICAO VDL4 Technical Manual [i.1]; • annex B provides a Bibliography. 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 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

6 ETSI EN 302 842-3 V1.4.1 (2015-04)
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 112,000 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 complies with ETSI EN 302 842-1 [1] and ETSI 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 (ETSI EN 301 842 [i.7] parts 1 to 4). 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.7] parts 1 to 4. This has led to a
non-standard form of numbering for new requirements in some places.
ETSI

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 112,000 MHz to 136,975 MHz as defined in ICAO VDL
SARPs [i.2].
The present 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 and the receiver may also 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" equipment.
The scope of the present document is limited to mobile stations. The equivalent specification for ground stations is
ETSI EN 301 842 [i.7].
A description of the scope of the VDL Mode 4 system is provided in part 2 of these technical specifications
(see ETSI EN 302 842-2 [2], clause 1).
ETSI EN 302 842-1 [1] deals with tests of the physical layer. ETSI 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;
• clause 7 provides protocol tests which emphasis the ADS-B, TIS-B, FIS-B and GNS-B functions of the
system;
ETSI
---------------------- Page: 7 ----------------------
8 ETSI EN 302 842-3 V1.4.1 (2015-04)
• annex A provides a detailed cross-reference to the relevant requirements contained in ICAO VDL4
Technical Manual [i.1];
• annex B provides a Bibliography.
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.

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 112,000 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 complies with ETSI EN 302 842-1 [1] and ETSI 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 (ETSI EN 301 842 [i.7] parts 1 to 4). 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.7] parts 1 to 4. This has led to a
non-standard form of numbering for new requirements in some places.

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 112,000 MHz to 136,975 MHz as defined in ICAO VDL
SARPs [i.2].
The present 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 and the receiver may also 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" equipment.
The scope of the present document is limited to mobile stations. The equivalent specification for ground stations is
ETSI EN 301 842 [i.7].
A description of the scope of the VDL Mode 4 system is provided in part 2 of these technical specifications
(see ETSI EN 302 842-2 [2], clause 1).
ETSI EN 302 842-1 [1] deals with tests of the physical layer. ETSI 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;
ETSI

8 ETSI EN 302 842-3 V1.4.0 (2014-12)
• 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.
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.
