Ilmselt on iga\u00fcks, kes on kunagi saatnud v\u00f5i saatnud sugulasi v\u00f5i s\u00f5pru lennukisse, kasutanud tasuta teenust Flightradar24. See on v\u00e4ga mugav viis lennuki asukoha reaalajas j\u00e4lgimiseks.<\/p>\n

T\u00e4idame selle teadmiste t\u00fchiku. Kuidas see t\u00f6\u00f6tab, j\u00e4tkame allpool.

Riistvara<\/h2>\n

\nEsimene k\u00fcsimus on \u2014 kust andmed tulevad. <\/p>\n

Iga tsiviillennuk on varustatud spetsiaalse edastiga, nii nimetatud ADS-B transponder<\/b>:<\/p>\n

\"Flightradar24
\n(foto Garmini veebisaidilt)<\/i><\/p>\n

See seade saadab sagedusel 1090 MHz spetsiaalseid signaale, mis sisaldavad p\u00f5hiteavet lennu, \u00f5hus\u00f5iduki t\u00fc\u00fcbi, selle koordinaatide, sihtkoha jne kohta. <\/p>\n

Signaal spektris n\u00e4eb v\u00e4lja umbes n\u00f5nda:<\/p>\n

\"Flightradar24
\n
\nJa mis meie jaoks k\u00f5ige olulisem, nende andmete dekodeerimine ei ole keeruline, piisab 8 dollari hinnaga RTL-SDR vastuv\u00f5tjast, mis on \u00fchendatud arvutiga. Idee on n\u00fc\u00fcd ilmselt selge \u2014 kui me kogume andmeid paljude vastuv\u00f5tjate kaudu, saame pildi, mis n\u00e4eb umbes selline v\u00e4lja:<\/p>\n

\"Flightradar24
\n
\nKuid see ei ole veel k\u00f5ik. Osad lennukid edastavad andmepakette, kuid nendes puuduvad GPS-koordinaadid. Kui andmeid vastu v\u00f5tta samaaegselt paljusid vastuv\u00f5tjaid, mille koordinaadid on teada, siis anal\u00fc\u00fcsides viivitusi erinevate vastuv\u00f5tjate vahel, saame teada \u00f5hus\u00f5iduki asukoha. Seda tehnoloogiat nimetatakse multilateratsiooniks (MLAT), sellest saab rohkem lugeda veebisaidil<\/a><\/noindex>.<\/p>\n

Ja l\u00f5puks, viimane k\u00fcsimus on \u2014 kuidas andmeid vastu v\u00f5etakse. Vastus on lihtne, vastuv\u00f5tja v\u00f5ib paigutada iga soovija, hinnaklass on 0 kuni 50 dollarit. N\u00e4iteks, nii n\u00e4eb v\u00e4lja Flightaware'i vastuv\u00f5tjate kaart:<\/p>\n

\"Flightradar24
\n
\nNagu n\u00e4ha, on Venemaa osa katvus piisavalt madal, seega on m\u00f5nel inimesel \u00fcsna v\u00f5imalik olla esimene.<\/p>\n

Andmete vastuv\u00f5tmiseks on vajalikud:<\/p>\n

\u2014 Raspberry Pi2\/3 interneti\u00fchendusega (hind alates 20$)
\n \u2014 RTL-SDR dongle (hind alates 10$)
\n \u2014 v\u00e4hemalt lihtne antenn, mis koosneb kahest 6,8 cm pikkusest traadist (1\/4 dipool 1090 MHz-le)<\/p>\n

Samuti on soovitatav valida koht, kus on v\u00e4hemalt osaline n\u00e4htavus taeva suunas, kuna gigahertsiseid signaale neelavad takistused nagu hooned v\u00f5i puud.<\/p>\n

Minul olid juba Raspberry Pi ja RTL-SDR, seega ei pidanud midagi ostma. Kuid iga\u00fcks v\u00f5ib proovida tasuta saada valmis vastuv\u00f5tjat \u2014 nii Flightradar kui ka Flightaware saadavad komplekte tasuta kasutajatele nendest piirkondadest, kus katvus hetkel puudulik. Taotlus tuleb saata j\u00e4rgmiselt lingilt (Flightradar<\/a><\/noindex> v\u00f5i Flightaware<\/a><\/noindex>), loomulikult on m\u00f5istlik proovida neid, kes elavad piisavalt eemal asuvates piirkondades.<\/p>\n

Kasutasin komplekti RTL-SDR V3, mis koos antenni ja mini-statiivi eest maksis 27 dollarit, koos tasuta kohaletoimetamisega Hiinast:<\/p>\n

\"Flightradar24
\n
\nMuide, kui teine boonus, siis k\u00f5ik, kes saadavad andmeid serverisse, saavad nii Flightradar24 kui ka Flightaware'i kaudu piiramatu juurdep\u00e4\u00e4su premium-kontole<\/b> ja k\u00f5igile serveri funktsioonidele (erinev juurdep\u00e4\u00e4s maksab umbes 50$\/kuus). Seega, kui keegi on huvitatud lennundusest ja soovib sellise konto laiaulatuslikku ligip\u00e4\u00e4su, on RTLSDR vastuv\u00f5tja paigaldamine \u00fcsna odav alternatiiv. <\/p>\n

Testimine<\/h2>\n

\nPaigaldamine on \u00e4\u00e4rmiselt lihtne, Raspberry Pi-l piisab, kui \u00fchendada vastuv\u00f5tja ja k\u00e4ivitada \u00fcks k\u00e4sk:<\/p>\n

sudo bash -c \"$(wget -O - http:\/\/repo.feed.flightradar24.com\/install_fr24_rpi.sh)\"<\/code><\/pre>\n
\nSkript k\u00fcsib vajalikku teavet (koordinaate ja vastuv\u00f5tja t\u00fc\u00fcpi, e-posti aadressi), p\u00e4rast seda t\u00f6\u00f6tab tarkvara automaatselt, kasutaja t\u00e4helepanu ei ole enam vajalik. Samuti on v\u00f5imalik aktiveerida premium-konto (FR24 jaoks lingil https:\/\/www.flightradar24.com\/premium\/signup?account=free<\/a><\/noindex>) ja kohe kasutada tavamoodulite v\u00f5imalusi (lennujuhtimise j\u00e4lgimine jne).<\/p>\n
Saate k\u00fclastada Raspberry Pi IP-aadressi lehte ja n\u00e4ha praegust olekut:<\/p>\n
\"Flightradar24
\nOluliselt rohkem teavet on v\u00f5imalik n\u00e4ha Flightradar24 konto lehelt:<\/p>\n

\n
\nElan 6. korrusel, suhteliselt l\u00e4hedal lennujaamale, nii et p\u00e4evase lennukite j\u00e4lgimise arv \u00fcletas 1000, isegi lihtsa aknaall-antenniga. Huvi p\u00e4rast, isegi sellise antenniga oli maksimaalne kaugus vastuv\u00f5etud \u00f5hus\u00f5idukisse 215 miili. Erinevaid antennide variante v\u00f5ib leida eBay-st, otsides ads-b antenna.<\/p>\n
Alternatiiv<\/h2>\n
\nBoonus neile, kellel piisavalt kannatust siiani lugeda. M\u00f5nel lugejal v\u00f5ib tekkida k\u00fcsimus: kas on v\u00f5imalik j\u00e4tta k\u00f5rvale kolmandad teenused nagu Flightradar? Loomulikult on see v\u00f5imalik, dekoodri k\u00e4ivitamine Raspberry Pi-l on v\u00f5imalik ka otse. Allalaadimiseks on l\u00e4htekood saadaval aadressil github.com\/antirez\/dump1090<\/a><\/noindex>.<\/p>\n
Pi-l piisab kolme k\u00e4su sisestamisest:<\/p>\n
git clone https:\/\/github.com\/antirez\/dump1090.git\ncd dump1090\/\nmake<\/code><\/pre>\n
\nSeej\u00e4rel saab dekoodri k\u00e4ivitada k\u00e4suga:<\/p>\n
.\/dump1090 --interactive --net<\/code><\/pre>\n
\nDekooder alustab t\u00f6\u00f6d ning n\u00e4eme \"toorandmeid\" \u2013 n\u00e4htavate \"lendude\" nimekirja:<\/p>\n
\"Flightradar24
\n
\nN\u00fc\u00fcd saab Raspberry Pi sirvijaga sisse logida ja imetleda oma kohalikku Flightradarit, pilt v\u00f5ib v\u00e4lja n\u00e4ha umbes nii:<\/p>\n
\"Flightradar24
\n
\nMiks see vajalik v\u00f5iks olla? Esiteks, lihtsalt huvi p\u00e4rast, teiseks, Flightradar24 filtreerib kahjuks osa andmeid ja n\u00e4itab mitte k\u00f5iki<\/i> lennukeid (n\u00e4iteks v\u00f5ivad mitte n\u00e4htavad olla s\u00f5jav\u00e4e-, valitsus- v\u00f5i era\u00e4ride lennukid). K\u00e4ivitades oma kohaliku teenuse, n\u00e4eme k\u00f5ike \"nagu on\", ilma igasuguste censuurideta. Kuid muidugi on andmete maht piiratud meie kohalikku asukohta ja antenni kvaliteet, samuti ei ole k\u00e4ttesaadav tehnoloogia MLAT. Dump1090 on avatud l\u00e4htekoodiga, nii et huvilised saavad isegi luua oma versiooni Flightradarist, koos mustade jackide ja muude vidinatega.<\/p>\n
J\u00e4reldused<\/h2>\n
\nNagu n\u00e4ha, pole k\u00f5ik nii keeruline, samas on see \u00fcsna huvitav ja odav. Hindade arusaamiseks: veel 10 aastat tagasi maksis vastuv\u00f5tja Airnav RadarBox umbes 1000$, n\u00fc\u00fcd saab RTL-SDR, mis teeb sama asja, k\u00e4tte 10$-ga.<\/p>\n
Minu puhul k\u00e4ivitati vastuv\u00f5tja ainult katsetamiseks, praktiliselt pole mingit m\u00f5tet seda pidevalt sees hoida, Euroopa osa katte tihedus on juba 100%. Venemaa \u00e4\u00e4realade elanikele, vastupidi, v\u00f5ib see olla \u00fcsna huvitav \u2013 tekib v\u00f5imalus teha kasulikku t\u00f6\u00f6d k\u00f5ikide maailmas reisijate jaoks, laiendades katmise ala, ning saada juurde Premium-kontole eeltoodud veebilehtedel.<\/p>\n
K\u00e4egu k\u00f5ikidel katsetel.<\/p>\n
