Radijska oprema za digitalno povezavo VHF (VDL) zrak-tla in zrak-zrak, 4. način - Tehnične karakteristike in merilne metode za aeronavtično mobilno (letalsko) opremo - 4. del: Funkcije sistema točka-točka

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 4. del tehničnih specifikacij. Pričujoči dokument zagotavlja, da bo oprema, ki jo certificira, združljiva z ustreznimi SARPs za ICAO VDL [2] in tehničnim priročnikom ICAO za VDL4. Proizvajalci morajo biti pozorni, da razpon uravnavanja za oddajnik lahko v prihodnje zajema kateri koli kanal25 kHz od 112.000 MHz do 117,975 MHz in za prejemnike kateri koli kanal25 kHz od 108.000 MHz do 117.975 MHz. Pričujoči dokument velja za »aeronavtično mobilno (za zračna vozila in ustrezno tudi za 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 [4]. Opis področja uporabe sistemov VDL, 4. način, je naveden v 2. delu EN 302 842-2 [6], klavzuli 1. EN 302 842-1 [5] obravnava preskuse fizične plasti, EN 302 842-2 [6] obravnava funkcionalnost plasti jedrne povezave in EN 302 842-3 [7] dodatno funkcionalnost oddajanja. Pričujoči dokument obravnava preskuse plasti podatkovne povezave (DLS) ter plasti povezave, ki zadostuje za podporo funkcionalnosti točka-točka. Bodite pozorni da je, kot je opisano v EN 302.842-2 [6], sistem, ki podpira funkcionalnost točka-točka, potreben za skladnost z EN 302.842-1 [5], EN 302.842-2 [6] in specifikacijo v pričujočem dokumentu. Pričujoči dokument vključuje:
- klavzulo 2, ki se sklicuje na ustrezne dokumente;
- klavzulo 3, ki podaja uporabljene splošne definicije, okrajšave in simbole;
- klavzulo 4, ki opisuje funkcije VHF mobilnih postaj točka-točka, 4. način;
- klavzulo 5, ki podaja specifikacije za zmogljivost za VDL mobilnih postaj, 4. način;
- klavzulo 6, ki podaja splošne zahteve za načrtovanje;
- klavzulo 7, ki podaja preskuse protokola za funkcije točka-točka sistema;
- dodatek A, ki podaja podrobno sklicevanje na ustrezne zahteve, zajete v
tehničnem priročniku ICAO za VDL4 [1];
- dodatek B, ki podaja bibliografijo;
- zgodovino 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 točka-točka in zagotoviti preskuse tistih preostalih zahtev, ki pod pogojem, da se narobe izvajajo, lahko povzročijo poslabšanje storitev, ki jih ponujajo postaje VDL, 4. način.
Fraze, ki zahtevajo in ki priporočajo
a) »Mora«:
- Uporaba besede »mora« nakazuje obvezni kriterij; npr. skladnost z določenim postopkom ali specifikacijo je obvezna in nobena druga možnost se ne sme uporabiti.
b) »Naj«:
- Uporaba besede »naj« (in fraze, kot je »Priporoča se, da …« itd.) nakazuje, da čeprav se postopek ali merilo šteje za prednostno možnost, se lahko uporabijo drugi postopki, specifikacije ali merila, pod pogojem, da proizvajalec, monter ali preizkuševalec lahko zagotovijo informacije ali podatke, s katerimi ustrezno podprejo in upravičijo drugo možnost.

ETSI ETSI EN 302 842-4 V1.2.2 (2010-12) 7 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 [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 [5] and EN 302 842-2 [6]. 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]). 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]. This has led to a non-standard form of numbering for new requirements in some places.
SIST EN 302 842-4 V1.2.2:2011



ETSI ETSI EN 302 842-4 V1.2.2 (2010-12) 8 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 [2]. The present document provides part 4 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 as applicable also 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]. A description of the scope of the VDL Mode 4 system is provided in part 2 of EN 302 842-2 [6], clause 1. EN 302 842-1 [5] deals with tests of the physical layer, EN 302 842-2 [6] deals with core link layer functionality and EN 302 842-3 [7] with additional broadcast functionality. The present document deals with tests of the datalink layer (DLS) and the link layer sufficient to support point-to-point functionality. Note that, as described in
EN 302 842-2 [6], a system supporting point-to-point functionality is required to conform to EN 302 842-1 [5],
EN 302 842-2 [6] and the specification in the present document. The present document includes: • 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 point-to-point functions; • clause 5 provides performance specifications for the VDL Mode 4 mobile station; • clause 6 provides general design requirements; • clause 7 provides protocol tests for the point-to-point functions of the system; • annex A provides a detailed cross-reference to the relevant requirements contained in
ICAO VDL4 Technical Manual [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 point-to-point functionality and to provide tests of those remaining requirements which, if wrongly implemented, could cause a deterioration in the service offered by other VDL Mode 4 stations.
