Radijska oprema za digitalno povezavo VHF (VDL) zrak-tla in zrak-zrak, 4. način - Tehnične karakteristike in merilne metode za aeronavtično mobilno (letalsko) opremo - 1. del: Fizična plast
Ta dokument velja za naslednje vrste radijske opreme:
• zelo visokofrekvenčno (VHF) digitalno povezavo (VDL) aeronavtičnih mobilnih (zračnih) radijskih oddajnikov, oddajnikov-prejemnikov in prejemnikov za komunikacije zrak-tla in zrak-zrak, 4. način, ki deluje v pasu VHF z uporabo modulacije frekvenčnega premičnega kodiranja prek filtra Gaussian (GFSK) z razmikom med kanali 25 kHz in je zmožna uravnavati na katerem koli izmed kanalov 25 kHz od 118.000 MHz do 136.975 MHz, kot je opredeljeno v SARPs ICAO za VDL [2].
Ta dokument zagotavlja 1. del tehničnih specifikacij.
Ta dokument zagotavlja, da bo oprema, ki jo certificira, združljiva z ustreznimi SARPs za ICAO VDL [2] in tehničnim priročnikom ICAO za VDL4 [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 [10].
Sistem VDL, 4. način, zagotavlja digitalne komunikacijske izmenjave med zračnim plovilom in zemeljskim sistemom ter drugimi aplikacijami, ki podpirajo nadzor 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);
• storitve zrak-zrak in tla-zrak;
• delovanje brez zemeljske infrastrukture.
Ta dokument je izpeljan iz naslednjih specifikacij:
• tehnični priročnik za VDL4 ICAO [1] in SARPs ICAO za VDL [2], izdanih pod okriljem
Mednarodne organizacije za civilno letalstvo (ICAO);
• drugih ustreznih standardov, kot je opredeljeno v točki 2.
Predvideva se, da proizvajalec lahko zagotovi opremo, ki podpira:
• samo storitve oddajanja;
• samo storitve točka-točka;
• storitve oddajanja in storitve točka-točka.
Ta dokument obravnava preskuse fizične plasti, potrebne za podporo vseh tipov opreme.
Ta dokument vključuje:
• točko 2, ki se sklicuje na ustrezne dokumente;
• točko 3, ki podaja uporabljene splošne definicije, okrajšave in simbole;
• točko 4, ki podaja splošni opis in arhitekturo za VDL, 4. način;
• točko 5, ki podaja funkcionalne specifikacije, ki veljajo za fizično plast, vključno z zahtevami za oddajnik/sprejemnik ter modulacijsko shemo;
• točko 6, ki podaja splošne zahteve za opremo VDL, 4 način;
• točko 7, ki podaja splošne zahteve za načrtovanje;
• točko 8, ki podaja splošne zahteve za okoljsko preskušanje;
• točko 9, ki podaja podrobne preskusne postopke za fizično plast;
• točko 10, ki podaja zahteve za nameščeno opremo;
• dodatek A, ki podaja podrobno sklicevanje na ustrezne zahteve, zajete v sklicu [1];
• dodatek B, ki podaja oceno zaloge povezav za VDL, 4. način;
• dodatek C, ki podaja bibliografijo;
• zgodovino dokumenta.
Podani so celotni preskusi fizične plasti, ki zelo ustrezajo standardnemu sklopu preskusov, uporabljenih za druge sisteme VDL.
OPOMBA: Preskusi letenja so opredeljeni v EN 302 842-2 [7].
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 in preizkuševalec lahko zagotovijo informacije ali podatke, s katerimi ustrezno podprejo in upravičijo drugo možnost.
