VHF air-ground Digital Link (VDL) Mode 4 radio equipment; Technical characteristics and methods of measurement for ground-based 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 ground-based radio transmitters and receivers for air-ground 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 VHF Digital Link (VDL) Standards and Recommended Practices (SARPs) [1].
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 VHF Digital Link (VDL) Standards and Recommended Practices (SARPs) [1] and VDL Mode 4 Technical Manual (TM) [i.1].
Manufacturers should note that in future the tuning range for the ground transceivers may also cover any 25 kHz channel from 108,000 MHz to 111,975 MHz.
The scope of the present document is limited to ground stations. The equivalent specification for airborne stations is ETSI EN 302 842 [i.4].
A description of the scope of the VDL Mode 4 system is provided in ETSI EN 301 842-2 [3], clause 1.
ETSI EN 301 842-1 [2] deals with tests of the physical layer. ETSI EN 301 842-2 [3] 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 ground-based 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 functionality in the ground-based 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, the minimum functionality demanded of a basic VDL Mode 4 ground-based transceiver unit (i.e. one that does not have a TIS-B, FIS-B or GNS-B processor housed within it) is to receive, from the TIS-B, FIS-B or GNS-B processor, all messages to be transmitted, and to transmit them. In the case of FIS-B there is an additional requirement to receive report request messages (from other VDL4 stations) and to pass those messages to the FIS-B processor.
It should be noted that the specifications for TIS-B, FIS-B and GNS-B in the present document represent a first step towards defining these applications, based on the work carried out as part of the NUP and MEDUP Programmes, and changes to the specifications for these services may therefore occur in the future.
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 ground station functionality to support ADS-B, TIS-B, FIS-B and GNS B;
• clause 5 provides performance specifications for the VDL Mode 4 ground 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;

Radijska oprema za digitalno povezavo VHF zrak-tla, 4. način - Tehnične karakteristike in merilne metode za talno opremo - 3. del: Dodatni vidiki v zvezi z radiodifuzijo
Ta dokument se uporablja za radijsko opremo naslednjih vrst:
• talne radijske oddajnike in sprejemnike za zelo visokofrekvenčno (VHF) digitalno povezavo (VDL) za komunikacije zrak-tla, 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) [1] za digitalne povezave ICAO VHF (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 in priporočenimi praksami (SARP) [1] za digitalne povezave ICAO VHF (VDL) in tehničnim priročnikom ICAO za digitalno povezavo VDL, 4. način (TM) [i.1].
Proizvajalci naj bodo pozorni, da razpon uravnavanja za talne oddajnike-sprejemnike lahko v prihodnje zajema tudi kateri koli kanal 25 kHz od 108,000 MHz do 111,975 MHz.
Področje uporabe tega dokumenta je omejeno na zemeljske postaje. Enakovredna specifikacija za letalske postaje je ETSI EN 302 842 [i.4].
Opis področja uporabe sistema VDL, 4. način, je naveden v standardu ETSI EN 301 842-2 [3], 1. točka.
ETSI EN 301 842-1 [2] obravnava preskuse fizične plasti. Standard ETSI EN 301 842-2 [3] 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 talni 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 talni opremi 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 storitev TIS-B, FIS-B ali GNS-B je tako minimalna funkcionalnost, ki se zahteva od osnovne talne oddajno-sprejemne enote VDL, 4. način (tj. enote, ki ne vsebuje procesorja TIS-B, FIS-B ali GNS-B), sprejemanje vseh sporočil procesorja TIS-B, FIS-B ali GNS-B, ki so namenjena oddajanju, in jih oddajati. V primeru storitve FIS-B je dodatna zahteva sprejemanje sporočil z zahtevami za poročila od drugih postaj VDL4 in posredovati ta sporočila procesorju FIS-B.
Poudariti je treba, da specifikacije za storitve TIS-B, FIS-B in GNS-B v tem dokumentu predstavljajo prvi korak do njihove opredelitve, osnovane na delu, ki je bilo izvedeno v okviru programov NUP in MEDUP, zato se lahko specifikacije za te storitve v prihodnosti spremenijo.
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 funkcionalnost zemeljskih postaj VDL, 4. način, za podporo storitev ADS-B, TIS-B, FIS-B in GNS B;
• točka 5 vsebuje specifikacije lastnosti zemeljskih 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 [i.1].
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 zahteve sistema, ki lahko v primeru nepravilnega izvajanja povzročijo poslabšanje storitve, ki jo zagotavljajo druge postaje VDL, 4. način.

1 Scope
The present document applies to the following radio equipment types:
• Very High Frequency (VHF) Digital Link (VDL) Mode 4 ground-based radio transmitters and receivers for
air-ground 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 VHF Digital Link (VDL) Standards and Recommended
Practices (SARPs) [1].
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
VHF Digital Link (VDL) Standards and Recommended Practices (SARPs) [1] and VDL Mode 4 Technical
Manual (TM) [i.1].
Manufacturers should note that in future the tuning range for the ground transceivers may also cover any 25 kHz
channel from 108,000 MHz to 111,975 MHz.
The scope of the present document is limited to ground stations. The equivalent specification for airborne stations is
ETSI EN 302 842 [i.4].
A description of the scope of the VDL Mode 4 system is provided in ETSI EN 301 842-2 [3], clause 1.
ETSI EN 301 842-1 [2] deals with tests of the physical layer. ETSI EN 301 842-2 [3] 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 ground-based 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 functionality in the ground-based 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, the minimum functionality demanded of a basic
VDL Mode 4 ground-based transceiver unit (i.e. one that does not have a TIS-B, FIS-B or GNS-B processor housed
within it) is to receive, from the TIS-B, FIS-B or GNS-B processor, all messages to be transmitted, and to transmit
them. In the case of FIS-B there is an additional requirement to receive report request messages (from other VDL4
stations) and to pass those messages to the FIS-B processor.
It should be noted that the specifications for TIS-B, FIS-B and GNS-B in the present document represent a first step
towards defining these applications, based on the work carried out as part of the NUP and MEDUP Programmes, and
changes to the specifications for these services may therefore occur in the future.
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 ground station functionality to support ADS-B, TIS-B, FIS-B and GNS B;
• clause 5 provides performance specifications for the VDL Mode 4 ground 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;

• annex A provides a detailed cross-reference to the relevant requirements contained in [i.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 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
ground-based radio transmitters, transceivers and receivers for air-ground 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 VHF Digital Link (VDL)
Standards and Recommended Practices (SARPs) [1].
The present document considers the additional broadcast functionality required to support ADS-B, TIS-B, FIS-B, and
GNS-B services.
The present document may be used to produce tests for the assessment of the performance of the equipment.
ETSI
---------------------- Page: 6 ----------------------
7 ETSI EN 301 842-3 V1.4.1 (2015-04)
1 Scope
The present document applies to the following radio equipment types:
• Very High Frequency (VHF) Digital Link (VDL) Mode 4 ground-based radio transmitters and receivers for
air-ground 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 VHF Digital Link (VDL) Standards and Recommended
Practices (SARPs) [1].
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
VHF Digital Link (VDL) Standards and Recommended Practices (SARPs) [1] and VDL Mode 4 Technical
Manual (TM) [i.1].
Manufacturers should note that in future the tuning range for the ground transceivers may also cover any 25 kHz
channel from 108,000 MHz to 111,975 MHz.
The scope of the present document is limited to ground stations. The equivalent specification for airborne stations is
ETSI EN 302 842 [i.4].
A description of the scope of the VDL Mode 4 system is provided in ETSI EN 301 842-2 [3], clause 1.
ETSI EN 301 842-1 [2] deals with tests of the physical layer. ETSI EN 301 842-2 [3] 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 ground-based 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 functionality in the ground-based 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, the minimum functionality demanded of a basic
VDL Mode 4 ground-based transceiver unit (i.e. one that does not have a TIS-B, FIS-B or GNS-B processor housed
within it) is to receive, from the TIS-B, FIS-B or GNS-B processor, all messages to be transmitted, and to transmit
them. In the case of FIS-B there is an additional requirement to receive report request messages (from other VDL4
stations) and to pass those messages to the FIS-B processor.
It should be noted that the specifications for TIS-B, FIS-B and GNS-B in the present document represent a first step
towards defining these applications, based on the work carried out as part of the NUP and MEDUP Programmes, and
changes to the specifications for these services may therefore occur in the future.
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 ground station functionality to support ADS-B, TIS-B, FIS-B and GNS B;
• clause 5 provides performance specifications for the VDL Mode 4 ground 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 301 842-3 V1.4.1 (2015-04)
• annex A provides a detailed cross-reference to the relevant requirements contained in [i.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 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.

1 Scope
The present document applies to the following radio equipment types:
• Very High Frequency (VHF) Digital Link (VDL) Mode 4 ground-based radio transmitters and receivers for
air-ground 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 VHF Digital Link (VDL) Standards and Recommended
Practices (SARPs) [1].
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
VHF Digital Link (VDL) Standards and Recommended Practices (SARPs) [1] and VDL Mode 4 Technical
Manual (TM) [i.1].
Manufacturers should note that in future the tuning range for the ground transceivers may also cover any 25 kHz
channel from 108,000 MHz to 111,975 MHz.
The scope of the present document is limited to ground stations. The equivalent specification for airborne stations is
ETSI EN 302 842 [i.4].
A description of the scope of the VDL Mode 4 system is provided in ETSI EN 301 842-2 [3], clause 1.
ETSI EN 301 842-1 [2] deals with tests of the physical layer. ETSI EN 301 842-2 [3] 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 ground-based 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 functionality in the ground-based 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, the minimum functionality demanded of a basic
VDL Mode 4 ground-based transceiver unit (i.e. one that does not have a TIS-B, FIS-B or GNS-B processor housed
within it) is to receive, from the TIS-B, FIS-B or GNS-B processor, all messages to be transmitted, and to transmit
them. In the case of FIS-B there is an additional requirement to receive report request messages (from other VDL4
stations) and to pass those messages to the FIS-B processor.
It should be noted that the specifications for TIS-B, FIS-B and GNS-B in the present document represent a first step
towards defining these applications, based on the work carried out as part of the NUP and MEDUP Programmes, and
changes to the specifications for these services may therefore occur in the future.
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 ground station functionality to support ADS-B, TIS-B, FIS-B and GNS B;
• clause 5 provides performance specifications for the VDL Mode 4 ground 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;

8 Draft ETSI EN 301 842-3 V1.4.0 (2014-12)
• annex A provides a detailed cross-reference to the relevant requirements contained in [i.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 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.
