Bahlobo, ngoSuku lweCosmonautics umncedisi wethu omncinci wabhabha ngempumelelo kwi-stratosphere! Ngexesha lokuhamba, umncedisi ebhodini ibhaluni ye-stratospheric yasasaza i-Intanethi, ifilimu kwaye idlulisa idatha yevidiyo kunye ne-telemetry emhlabeni. Kwaye asinakulinda ukukuxelela ukuba konke kwahamba njani kwaye zeziphi izinto ezothusayo ezazikho (kakuhle, besiya kwenza ntoni ngaphandle kwabo?).
Imvelaphi encinci kunye namakhonkco aluncedo kwabo baphose yonke into:
- Isithuba malunga kwi-stratosphere (esidibene nayo xa sisebenza ngexesha lokuqaliswa).
- senze njani"Β»iprojekthi- yabalandeli be-porn ye-geek, eneenkcukacha kunye nekhowudi.
- iprojekthi, apho kwakunokwenzeka ukujonga intshukumo yeprobe kunye netelemetry ngexesha lokwenyani.
- Iinkqubo zonxibelelwano emajukujukwini esazisebenzisileyo kwiprojekthi.
- Isicatshulwa indulula umncedisi kwi stratosphere.
Ekubeni sasifuna ngokwenene ukuqalisa ngoSuku lweCosmonautics saza safumana imvume esemthethweni yokusebenzisa i-airspace kwangolo suku, kwafuneka siziqhelanise nemozulu. Kwaye ukuze umoya ungavutheli ibhaluni ye-stratospheric ngaphaya kwemida yendawo evunyelweyo, kwafuneka sinciphise ukuphakama kokunyuka - endaweni ye-30 km siye saphakama ukuya kwi-22,7. Kodwa le sele iyistratosphere, kwaye malunga nokuphinda kabini ukuphakama kweenqwelomoya zabakhweli zibhabha namhlanje.
Uqhagamshelo lwe-Intanethi kunye nebhaluni yestratospheric bezinzile kulo lonke uhambo lokubhabha. Imiyalezo yakho yamkelwe yaza yaboniswa, kwaye sazalisa nakuphi na ukumiswa ngeengcaphuno ezivela kuthethathethwano lukaGagarin noMhlaba kwiminyaka engama-58 eyadlulayo :)
Ngokutsho kwe-telemetry, yayingu-60 0C ngaphandle, kwaye ngaphakathi kwebhokisi ye-hermetic yafikelela -22 0C, kodwa yonke into yayisebenza ngokuzinzileyo.
Igrafu yotshintsho kubushushu ngaphakathi (apha nangaphezulu kwisikali X, amashumi emizuzu abonisiwe):
Omnye umfuniselo wedijithali ohambisa isantya esiphezulu wafakwa ebhodini. Lo ngumzamo wethu wokwenza i-Wi-Fi enesantya esiphezulu, kwaye asikakulungeli ukuveza iinkcukacha zoyilo lwayo okwangoku. Ngale transmitter besifuna ukusasaza ividiyo kwi-intanethi. Kwaye eneneni, ngaphandle kwamafu, sifumene umqondiso wevidiyo ovela kwiGoPro ekhwele ibhaluni yestratospheric kumgama ongange-30 km. Kodwa emva kokufumana ividiyo kwiziko lethu lolawulo, kwakungenakwenzeka ukuyihambisa kwi-Intanethi phezu komhlaba ... Ngoku siya kukuxelela ukuba kutheni.
Kungekudala siza kubonisa ushicilelo lwevidiyo yokubhabha ukusuka kwiikhamera ezingaphakathi, kodwa okwangoku unokubukela ukurekhodwa kwe-intanethi kwiprobe.
Eyona nto imangalisayo yayisilindele: ukusebenza kakubi kakhulu kwemodem ye-4G kwi-MCC yethu, eyenze ukuba kube nzima ukuhambisa ividiyo kwi-intanethi. Nangona i-probe ifunyenwe ngempumelelo kwaye idluliselwe imiyalezo nge-Intanethi, yamkelwa ngumncedisi - sifumene uqinisekiso lwenkonzo kuyo kwaye sayibona iboniswe kwiscreen ngokusasazwa kwevidiyo. Sasinenkxalabo malunga nonxibelelwano kunye neesathelayithi kunye nokuhanjiswa komqondiso kuMhlaba, kodwa akukho mntu wayelindele ukulalela okunjalo ukuba yayiyi-intanethi ye-4G ye-intanethi eya kuba yikhonkco ebuthathaka.
Kwaye kungekhona entlango ethile, kodwa engekude nePereslavl-Zalessky, kwindawo ethi, ngokwe-MTS kunye neemephu zeMegaFon, ihlanganiswe kakuhle ne-4G. Kwi-MCC yethu yeselula bekukho i-router ye-Kroks ap-205m1-4gx2h ephucukileyo, apho kufakwe khona iiSIM khadi ezimbini, kwaye bekufanele ukuba ishwankathele itrafikhi kubo ukuze sikwazi ukusasaza ividiyo ngokupheleleyo kwi-Intanethi. Sade safaka ii-eriyali zephaneli zangaphandle nge-18 dB inzuzo. Kodwa esi siqwenga se-hardware sisebenze ngokucekisekayo. Inkonzo yenkxaso ye-Kroks inokusicebisa kuphela ukuba silayishe i-firmware yamva nje, kodwa oku akuzange kuncede, kwaye isantya samakhadi amabini e-SIM ye-4G sajika saba sibi kakhulu kunesantya seSIM khadi kwimodem ye-USB eqhelekileyo. Ke, ukuba unokundixelela ukuba yeyiphi i-hardware engcono ukuququzelela ukuhanjiswa kwedatha kunye ne-4G yeziteshi kwixesha elizayo, bhala kumagqabantshintshi.
Ubalo lwethu lomkhondo luye lwachaneka; kwakungekho nto imangalisayo. Saba nethamsanqa, ibhaluni yestratospheric yahlala kumhlaba othambileyo wepeat oziimitha ezili-10 ukusuka kwindawo yokugcina amanzi kunye neekhilomitha ezingama-70 ukusuka kwindawo yokuqaliswa. Umgama wegrafu yeGPS:
Kwaye yile ndlela isantya sokubhabha esithe nkqo sebhaluni yestratospheric satshintsha:
Kuyinyani, esinye seziboniso zimbini asizange sisinde ekufikeni (ewe, bekukho ezimbini zazo, njengeekhamera zeGoPro; ukuphinda-phinda yindlela elungileyo yokwandisa ukuthembeka); kwividiyo unokubona ukuba ihambe njani ngemigca kwaye yajika. icimile. Kodwa zonke ezinye izixhobo zasinda ekuhleni ngaphandle kweengxaki.
Izigqibo kuvavanyo kunye nomgangatho wonxibelelwano lwe-Intanethi.
Indlela iseva esebenze ngayo ijongeka ngolu hlobo: kwiphepha lokufikela ungathumela imiyalezo ebhaliweyo kumncedisi ngefomu. Baye bathunyelwa nge-HTTP protocol ngokusebenzisa iinkqubo ezizimeleyo zonxibelelwano lwesathelayithi ezi-2 kwikhompyutheni emisiwe phantsi kwebhaluni ye-stratospheric, kwaye idlulisela le datha eMhlabeni, kodwa kungekhona ngendlela efanayo ngesathelayithi, kodwa ngejelo lomsakazo. Ke, saqonda ukuba iseva ifumana idatha ngokubanzi, kwaye inokusasaza i-Intanethi kwi-stratosphere. Kwiphepha elinye lokumisa, ishedyuli yokubhabha yebhaluni yestratospheric ibonisiwe, kwaye amanqaku okufumana umyalezo wakho ngamnye aphawulwe kuyo. Oko kukuthi, unokulandelela indlela kunye nokuphakama kwe "sky-high server" ngexesha langempela.
Lilonke, abathathi-nxaxheba bethu bathumele imiyalezo ye-166 ukusuka kwiphepha lokufika, apho i-125 (75%) ihanjiswe ngempumelelo kumncedisi. Uluhlu lokulibaziseka phakathi kokuthumela nokufumana lukhulu kakhulu, ukusuka kwi-0 ukuya kwi-59 imizuzwana (umyinge wokulibaziseka imizuzwana ye-32).
Asifumananga naluphi na ulungelelwaniso olubonakalayo phakathi kobude kunye nenqanaba le-latency:
Ukusuka kule grafu kuyacaca ukuba inqanaba lokulibaziseka alixhomekekanga nangayiphi na indlela kumgama osuka kwindawo yokuphehlelelwa, oko kukuthi, sithumele ngokunyanisekileyo imiyalezo yakho ngeesathelayithi, hayi ukusuka emhlabeni:
Esona sigqibo siphambili kuvavanyo lwethu kukuba sinokufumana kwaye sisasaze imiqondiso ye-Intanethi ukusuka kwiibhaluni zestratospheric, kwaye iskimu esinjalo sinelungelo lokubakho.
Njengoko ukhumbula, sathembisa ukuthelekisa unxibelelwano lwe-Iridium kunye ne-GlobalStar (asizange sifumane imodem yesiThunywa ngexesha). Ukuzinza komsebenzi wabo kwii-latitudes zethu kwajika kwaphantse kwafana. Ngaphezu kwamafu ulwamkelo luzinzile. Kubuhlungu ukuba abameli benkqubo yasekhaya "yeMthunywa" bahlolisise kwaye balungiselele into ethile apho, kodwa abazange bakwazi ukubonelela nantoni na yokuvavanya.
Izicwangciso zekamva
Ngoku, sicwangcisa iprojekthi elandelayo, intsonkothe ββngakumbi. Ngoku sisebenza kwiimbono ezahlukeneyo, umzekelo, ukuba ngaba kufuneka silungiselele unxibelelwano lwelaser olunesantya esiphezulu phakathi kweebhaluni ezimbini zestratospheric ukuze sizisebenzise njengabaphindayo. Kwixesha elizayo, sifuna ukwandisa inani leendawo zokufikelela kwaye siqinisekise isantya soqhagamshelo lwe-Intanethi oluzinzileyo ukuya kuthi ga kwi-1 Mbit / isekhondi ngaphakathi kwe-radius ye-100-150 km, ukwenzela ukuba kwixesha elizayo liqalise iingxaki ngokuhambisa ividiyo ye-intanethi kwi-Intanethi. ayisayi kuphinda ivele.
