Shamwari, paZuva reCosmonautics sevha yedu diki yakabudirira kubhururuka ichipinda mu stratosphere! Munguva yekubhururuka, sevha yaive mubhodhi stratospheric balloon yakagovera iyo Internet, yakadhirowa uye kutumira vhidhiyo uye telemetry data pasi. Uye isu hatigone kumirira kukuudza kuti zvese zvakafamba sei uye ndezvipi zvinoshamisa zvaivepo (zvakanaka, taizoita sei pasina ivo?).
Idiki kumashure uye anobatsira malink kune avo vakapotsa zvese:
- A post about kupinda mu stratosphere (iyo yatakasangana nayo mukuita panguva yekutanga).
- taita sei"Β»purojekiti - yevateveri ve geek porn, ine ruzivo uye kodhi.
- purojekiti, kwazvaikwanisika kutarisa mafambiro eprobe uye telemetry munguva chaiyo.
- hurongwa hwekutaurirana hwemuchadenga hwatakashandisa muchirongwa.
- Text kutanga sevha mu stratosphere.
Sezvo taida chaizvo kutanga paZuva reCosmonautics uye takagamuchira mvumo yepamutemo yekushandisa nzvimbo yemhepo pazuva iroro chairo, taifanira kuchinjira kumamiriro ekunze. Uye kuitira kuti mhepo irege kuvhuvhuta bharumu ye stratospheric kupfuura miganhu yenzvimbo yakabvumidzwa, taifanira kudzikamisa kureba - panzvimbo yemakiromita makumi matatu isu takasimuka kusvika 30. Asi iyi yatove iyo stratosphere, uye inosvika zvakapetwa kaviri pakukwirira kupfuura ndege dzinobhururuka nhasi.
Kubatana kweInternet nebharumu yestratospheric kwaive kwakadzikama panguva yese yekubhururuka. Mameseji ako akagamuchirwa uye akaratidzwa, uye isu takazadza chero kumbomira nekotesheni kubva munhaurirano dzaGagarin nePasi makore makumi mashanu nemasere apfuura :)
Maererano ne telemetry, yaiva -60 0C kunze, uye mukati mebhokisi re hermetic yakasvika -22 0C, asi zvose zvakashanda zvakasimba.
Girafu yekuchinja kwekushisa mukati (pano uye mberi pachiyero X, makumi emaminitsi anoratidzwa):
Imwe yekuyedza yedhijitari yakakwirira-kumhanya transmitter yakaiswa mubhodhi. Uku ndiko kuyedza kwedu kugadzira yakakwira-kumhanya Wi-Fi, uye isu hatisati tagadzirira kuburitsa ruzivo rwekugadzirwa kwayo parizvino. Neiyi transmitter taida kutepfenyura vhidhiyo online. Uye zvechokwadi, kunyangwe kuine makore, takagamuchira vhidhiyo chiratidzo kubva kuGoPro pabhodhi stratospheric balloon chinhambwe chinosvika makumi matatu km. Asi takagamuchira vhidhiyo munzvimbo yedu yekutonga, zvakanga zvisingakwanisi kuitumira kuInternet pamusoro pevhu ... Iye zvino tichakuudza kuti sei.
Tichakurumidza kuratidza marekodhi evhidhiyo ekubhururuka kubva pamakamera, asi ikozvino unogona kuona kurekodha pamhepo kubva kuprobe.
Chishamiso chikuru chakatimirira: kuita kwakashata kwe4G modem muMCC yedu, izvo zvakaita kuti zvisaite kufambisa vhidhiyo online. Kunyangwe iyo probe yakagamuchirwa uye kutumira mameseji kuburikidza neInternet, yakagamuchirwa nesevha - takagamuchira zvisimbiso zvesevhisi kubva kwairi uye takazviona zvichiratidzwa pachiratidziro kuburikidza nevhidhiyo kutepfenyura. Isu taive nekunetsekana nezve kutaurirana nemasetellite uye kufambisa kwemasaini kuNyika, asi hapana aitarisira kuvandira kwakadaro kuti yaive mobile 4G Internet yaizove iyo isina simba link.
Uye kwete mune rimwe renje, asi kwete kure nePereslavl-Zalessky, munzvimbo iyo, maererano neMTS uye MegaFon mepu, yakafukidzwa zvakanaka ne4G. Mune yedu mobile MCC maive neyakaomesesa Kroks ap-205m1-4gx2h router, mairi maviri SIM makadhi anoiswa, uye iyo yaifanirwa kupfupisa traffic pavari kuti isu tikwanise kutepfenyura zvizere vhidhiyo kuInternet. Isu takatoisa ekunze mapaneru antenna ane 18 dB kuwana. Asi chidimbu chehardware ichi chakashanda zvinosemesa. Iyo Kroks yekutsigira sevhisi inogona chete kutipa zano kurodha yazvino firmware, asi izvi hazvina kubatsira, uye kumhanya kwemaviri SIM makadhi e4G kwakave kwakaipisisa kupfuura kumhanya kweimwe SIM kadhi mune yenguva dzose USB modem. Saka, kana iwe uchikwanisa kundiudza kuti ndechipi chidimbu chehardware chiri nani kuronga kufambisa kwedata pamwe nekupfupisa kwe4G chiteshi nguva inotevera, nyora mune zvakataurwa.
Maverengero edu ekuverengera akave echokwadi; pakanga pasina zvinoshamisa. Isu takanga tine rombo rakanaka, iyo stratospheric balloon yakamhara pane yakapfava peat ivhu 10 metres kubva padhamu uye 70 km kubva panzvimbo yekutanga. GPS chinhambwe girafu:
Uye iyi ndiyo nzira yakachinjika yekumhanya yekubhururuka kwebharumu ye stratospheric:
Chokwadi, chimwe chezviratidziro zviviri hachina kupona pakumhara (hongu, pakanga paine maviri acho, semakamera eGoPro; kudzokorora inzira yakanaka yekuwedzera kuvimbika); muvhidhiyo unogona kuona mafambiro aakaita mumitsara uye akatendeuka. off. Asi mimwe michina yese yakapona pakumhara pasina matambudziko.
Mhedziso pakuedza uye kunaka kwekutaurirana kweInternet.
Mashandiro aiita sevha akaita seizvi: pane peji rekutora unogona kutumira mameseji kune server kuburikidza nefomu. Iwo aifambiswa kuburikidza neHTTP protocol kuburikidza ne 2 yakazvimirira satellite yekutaurirana masisitimu kune komputa yakamiswa pasi pe stratospheric balloon, uye yakaendesa iyi data kuNyika, asi kwete nenzira imwechete kuburikidza nesetiraiti, asi kuburikidza neredhiyo chiteshi. Nekudaro, isu takanzwisisa kuti sevha kazhinji inogamuchira data, uye kuti inogona kugovera iyo Internet kubva kune stratosphere. Pa peji rimwe chete rekumhara, hurongwa hwekubhururuka hwebharumu re stratospheric hwakaratidzwa, uye mapoinzi ekugamuchira meseji yako yega yega akaiswa pairi. Ndokunge, iwe unogona kuteedzera nzira uye urefu hwe "sky-high server" munguva chaiyo.
Pakazara, vatori vechikamu vedu vakatumira mameseji 166 kubva papeji yekumhara, iyo 125 (75%) yakaunzwa zvakabudirira kune server. Rudzi rwekunonoka pakati pekutumira nekugamuchira rwakanga rwakakura kwazvo, kubva pa0 kusvika ku59 seconds (avhareji yekunonoka 32 seconds).
Hatina kuwana chero hukama hunoonekwa pakati pehurefu uye latency level:
Kubva pane iyi girafu zviri pachena kuti nhanho yekunonoka haina kutsamira munzira ipi neipi kubva kune yekutanga saiti, ndiko kuti, isu takatendeseka meseji yako kuburikidza nema satellite, uye kwete kubva pasi:
Mhedziso huru kubva mukuedza kwedu ndeyekuti isu tinogona kugamuchira nekugovera masaini eInternet kubva kumabharumu e stratospheric, uye chirongwa chakadaro chine kodzero yekuvepo.
Sezvaunorangarira, takavimbisa kuenzanisa kutaurirana kweIridium neGlobalStar (hatina kumbogamuchira Messenger modem nenguva). Kugadzikana kwebasa ravo munharaunda yedu kwakave kwakada kufanana. Pamusoro pemakore kugamuchirwa kwakanyatsogadzikana. Zvinosiririsa kuti vamiriri ve "Messenger" yepamba vakatarisa uye vakagadzirira chimwe chinhu ipapo, asi havana kumbokwanisa kupa chero chinhu chekuyedzwa.
Zvirongwa zvemangwana
Iye zvino, tiri kuronga chirongwa chinotevera, chakatonyanya kuoma. Parizvino tiri kushanda pamazano akasiyana, semuenzaniso, kana isu tichifanira kuronga yakanyanya-kumhanya laser kutaurirana pakati pemabharuni maviri estratospheric kuitira kuti tishandise seanodzokorora. Mune ramangwana, isu tinoda kuwedzera huwandu hwenzvimbo dzekuwana uye kuona yakagadzikana yekubatanidza Internet kumhanya inosvika 1 Mbit/sec mukati meradius ye100-150 km, kuitira kuti mune inotevera inotangisa matambudziko nekutumira online vhidhiyo kuInternet. haichazomukizve.
