Flightradar24 - imagwira ntchito bwanji?

Mwina aliyense yemwe adakumanapo kapena kuwonana ndi achibale kapena abwenzi pandege wagwiritsa ntchito ntchito yaulere ya Flightradar24. Iyi ndi njira yabwino kwambiri yowonera momwe ndege ilili munthawi yeniyeni.

Monga momwe kafukufuku wa abwenzi adawonetsera, anthu ochepa amadziwa kuti ntchitoyi imathandizidwa ndi okonda omwe amatumiza deta ku seva. Ndi ochepa omwe amadziwa kuti aliyense angathe kulowa nawo ntchitoyi.

Tiyeni tikwaniritse kusiyana kumeneku. Tipitiliza m'munsimu momwe zimagwirira ntchito.

Iron

Funso loyamba ndi komwe deta imachokera.

Ndege iliyonse ya anthu wamba imakhala ndi cholumikizira chapadera, chotchedwa ADS-B transponder:

(chithunzi kuchokera patsamba la Garmin)

Chipangizochi chimatumiza mauthenga apadera pafupipafupi 1090 MHz okhala ndi magawo oyambira ndege, mtundu wa ndege, zolumikizira zake, kopita, ndi zina zambiri.

Chizindikiro pa sipekitiramu chikuwoneka motere:

Ndipo chomwe chili chofunikira kwambiri kwa ife ndikuti kuyika deta iyi sikovuta; cholandila cha RTL-SDR, chodula pafupifupi $8, cholumikizidwa ndi kompyuta ndichokwanira. Kwenikweni, lingalirolo likuwonekera kale - ngati tisonkhanitsa deta kuchokera kwa olandila ambiri, tidzapeza chithunzi chonga ichi:

Koma si zokhazo. Ndege zina zimatumiza mapaketi a data, koma mulibe zolumikizira za GPS. Ngati mulandira deta nthawi imodzi kuchokera kwa olandila ambiri, omwe amagwirizanitsa omwe amadziwika, ndiye pofufuza kuchedwa kwa olandila osiyanasiyana, mukhoza kudziwa malo a ndegeyo. Tekinolojeyi imatchedwa multilateration (MLAT), mutha kuwerenga zambiri za izo Online.

Ndipo potsiriza, funso lomaliza ndi momwe deta imalandirira. Yankho ndi losavuta, aliyense akhoza kulandira wolandila, mtengo wake umachokera ku $ 0 mpaka $ 50. Mwachitsanzo, izi ndi momwe mapu olandila chithandizo cha Flightaware amawonekera:

Monga mukuonera, kuphimba gawo la Russia kumasiya zambiri, kotero ena ali ndi mwayi wokhala woyamba.

Kuti mulandire data muyenera:

- Raspberry Pi2/3 yokhala ndi intaneti yolumikizidwa (mtengo kuchokera ku $ 20)
- RTL-SDR dongle (mtengo kuchokera $10)
- osachepera mlongoti wosavuta wokhala ndi zidutswa ziwiri za waya, iliyonse kutalika kwa 2 cm (6.8/1 dipole pa 4 MHz)

Ndikofunikiranso kukhala ndi malo okhala ndi mawonekedwe otseguka pang'ono pang'ono pang'ono a thambo, chifukwa... Ma frequency a Gigahertz amatengedwa ndi zopinga monga nyumba kapena mitengo.

Ndinali kale ndi Raspberry Pi ndi RTL-SDR, kotero sindinayenera kugula kalikonse. Koma aliyense atha kuyesa kupeza cholandila chokonzekera kwaulere - ndipo Flightradar ndi Flightaware akutumiza zida zaulere kwa ogwiritsa ntchito m'malo omwe kufalitsa sikukwanira. Mutha kutumiza pempho pogwiritsa ntchito ulalo (Ndege radar kapena Flightaware), ndithudi, ndi bwino kuyesera kwa iwo omwe amakhala kudera lakutali.

Ndidagwiritsa ntchito zida za RTL-SDR V3, zomwe pamodzi ndi mlongoti ndi mini tripod zidawononga $27 ndikutumiza kwaulere kuchokera ku China:

Mwa njira, ngati bonasi yachiwiri, onse Flightradar24 ndi Flightaware amapereka aliyense amene amatumiza deta ku seva. mwayi wopanda malire ku akaunti ya premium ndi ntchito zonse za seva (payokha, kupeza koteroko kumawononga pafupifupi $ 50 / mwezi). Chifukwa chake ngati wina ali ndi chidwi ndi kayendetsedwe ka ndege ndipo akufuna kukhala ndi mwayi wofikira ku akaunti yotere, kukhazikitsa cholandila cha RTLSDR ndi njira yotsika mtengo kwambiri.

Kuyesa

Kuyika ndikosavuta kwambiri; pa Raspberry Pi mumangofunika kulumikiza wolandila ndikuyendetsa lamulo limodzi:

sudo bash -c "$(wget -O - http://repo.feed.flightradar24.com/install_fr24_rpi.sh)"

Script idzapempha deta yofunikira (zogwirizanitsa ndi mtundu wa wolandila, imelo), ndiye kuti pulogalamuyo idzagwira ntchito yokha, yosafunanso chidwi cha ogwiritsa ntchito. Nthawi yomweyo, mutha kuyambitsa akaunti yoyamba (ya FR24, tsatirani ulalo https://www.flightradar24.com/premium/signup?account=free) ndipo nthawi yomweyo gwiritsani ntchito mphamvu zake zonse (mayendedwe owuluka, etc.).

Mutha kupita ku tsamba la IP la Raspberry Pi ndikuwona momwe zilili pano:

Zambiri zambiri zitha kuwoneka patsamba la akaunti ya Flightradar24:

Ndimakhala pansanjika ya 6 pafupi ndi bwalo la ndege, kotero kuchuluka kwa ndege zomwe zimawonedwa patsiku kunali kopitilira 1000, ngakhale ndi mlongoti wosavuta pawindo. Chochititsa chidwi n'chakuti, ngakhale ndi mlongoti woterowo, maulendo apamwamba a ndege omwe adalandira anali 215 mailosi. Zosankha zosiyanasiyana za mlongoti zitha kupezeka pa ebay posaka ads-b antenna.

Zina

Bonasi kwa iwo omwe anali ndi chipiriro kuti awerenge mpaka pano. Owerenga ena atha kukhala ndi funso: kodi ndizotheka kuchita popanda ntchito za chipani chachitatu ngati Flightradar? Zachidziwikire, mutha kuyendetsa decoder pa Raspberry Pi mwachindunji. Mukhoza kukopera magwero pa github.com/antirez/dump1090.

Ndikokwanira kulemba malamulo atatu pa Raspberry Pi:

git clone https://github.com/antirez/dump1090.git
cd dump1090/
make

Kenako decoder ikhoza kukhazikitsidwa ndi lamulo:

./dump1090 --interactive --net

Decoder ikuyamba kugwira ntchito, ndipo tikuwona "zambiri" - mndandanda wa "ma board" owoneka:

Tsopano mutha kupita ku Raspberry Pi ndi msakatuli ndikusilira yanu, Flightradar yakomweko, chithunzichi chikhoza kuwoneka chonchi:

Chifukwa chiyani izi zingakhale zofunikira? Choyamba, chifukwa cha chidwi, ndipo kachiwiri, Flightradar24, mwatsoka, imasefa zina mwazinthu ndi ziwonetsero. osati onse ndege (mwachitsanzo, asilikali, boma, kapena ndege zamalonda sizingasonyezedwe). Poyambitsa ntchito yathu yakumaloko, timawona zonse "monga momwe zilili", popanda kuwunika kulikonse. Koma, ndithudi, kuchuluka kwa deta kumachepa ndi malo athu apafupi komanso ubwino wa antenna, ndipo teknoloji ya MLAT sidzakhalapo. Dump1090 imapezeka mu code source, kotero aliyense atha kupanga mtundu wake wa Flightradar, ndi blackjack ndi mabelu ena ndi mluzu.

anapezazo

Monga mukuonera, sizovuta kwambiri, ndipo ndizosangalatsa komanso zotsika mtengo. Kuti timvetse mtengo wake: zaka 10 zapitazo, cholandirira cha Airnav RadarBox chinadula mtengo wake pafupifupi 1000$, tsopano mutha kupeza RTL-SDR yomwe imachita zomwezo pa $10.

Kwa ine, wolandirayo adakhazikitsidwa kuti ayesedwe; palibe zomveka pozisunga nthawi zonse; kuchulukitsitsa kwa gawo la ku Europe kumafika kale 100%. Kwa anthu okhala kumadera akumidzi aku Russia, m'malo mwake, izi zitha kukhala zosangalatsa - pali mwayi woti onse achite zinthu zothandiza kwa apaulendo padziko lonse lapansi, kukulitsa malo ofikirako, ndikupeza mwayi wopeza akaunti ya Premium ya zomwe tatchulazi. masamba.

Odala kuyesa aliyense.
