Bangane, ngoSuku Lwe-Cosmonautics iseva yethu encane indize ngempumelelo ku-stratosphere! Ngesikhathi sendiza, iseva egibele ibhaluni ye-stratospheric isabalalise i-inthanethi, yathwebula futhi yadlulisela ividiyo kanye nedatha ye-telemetry phansi. Futhi asikwazi ukulinda ukukutshela ukuthi konke kuhambe kanjani nokuthi yiziphi izimanga ezikhona (kahle, besizokwenzani ngaphandle kwabo?).
Isizinda esincane nezixhumanisi eziwusizo zalabo abaphuthelwe yikho konke:
- Okuthunyelwe mayelana ku-stratosphere (esihlangabezane nayo ngesikhathi sokwethulwa).
- Senze kanjani"Β»iphrojekthi - yabalandeli be-geek porn, enemininingwane nekhodi.
- iphrojekthi, lapho bekungenzeka khona ukuqapha ukunyakaza kwe-probe kanye ne-telemetry ngesikhathi sangempela.
- izinhlelo zokuxhumana emkhathini esizisebenzise kuphrojekthi.
- Umbhalo kwethula iseva ku-stratosphere.
Njengoba sasifuna ngempela ukwethula ngoSuku Lwe-Cosmonautics futhi sathola imvume esemthethweni yokusebenzisa indawo yezindiza ngalo kanye lolo suku, kwadingeka sizivumelanise nesimo sezulu. Futhi ukuze umoya ungavuthi ibhaluni le-stratospheric ngaphesheya kwemingcele yendawo evunyelwe, kwakudingeka sinciphise ukuphakama kokukhuphuka - esikhundleni samakhilomitha angu-30 sikhuphukele ku-22,7. Kodwa lokhu kakade kuyi-stratosphere, futhi cishe ukuphakama okuphindwe kabili kunezindiza zabagibeli namuhla.
Uxhumo lwe-inthanethi nebhaluni ye-stratospheric belizinzile kuyo yonke indiza. Imilayezo yakho yamukelwe futhi yaboniswa, futhi sagcwalisa noma yikuphi ukumiswa ngezingcaphuno ezivela ezingxoxweni zikaGagarin Nomhlaba eminyakeni engu-58 edlule :)
Ngokusho kwe-telemetry, yayiyi--60 0C ngaphandle, futhi ngaphakathi kwebhokisi le-hermetic ifinyelele -22 0C, kodwa yonke into yasebenza ngokuzinza.
Igrafu yezinguquko kuzinga lokushisa ngaphakathi (lapha nangaphezulu esikalini X, amashumi emizuzu ayaboniswa):
Esinye isisetshenziswa sokuhlola esinesivinini esiphezulu sedijithali sifakwe ebhodini. Lona umzamo wethu wokwenza i-Wi-Fi enesivinini esikhulu, futhi asikakalungeli ukuveza imininingwane yomklamo wayo okwamanje. Ngalesi sidlulisi besifuna ukusakaza ividiyo ku-inthanethi. Futhi ngempela, naphezu kwamafu, sithole isignali yevidiyo evela ku-GoPro egibele ibhaluni ye-stratospheric ebangeni elingafika ku-30 ββkm. Kodwa ngemva kokuthola ividiyo esikhungweni sethu sokulawula, akwenzekanga ukuyidlulisela ku-inthanethi phansi... Manje sizokutshela ukuthi kungani.
Maduze sizobonisa okurekhodiwe kwevidiyo yendiza evela kumakhamera angaphakathi ebhodini, kodwa okwamanje ungabuka ukurekhodwa ku-inthanethi kusuka kuphenyo
Isimanga esikhulu besisilindile: ukusebenza kabi kakhulu kwemodemu ye-4G ku-MCC yethu, okwenze kwaba nzima ukudlulisa ividiyo ku-inthanethi. Yize uphenyo lwamukelwe ngempumelelo futhi lwadluliswa imiyalezo nge-inthanethi, yamukelwe iseva - sithole iziqinisekiso zesevisi kuyo futhi sazibona ziboniswa esikrinini ngokusakazwa kwevidiyo. Besinokukhathazeka mayelana nokuxhumana namasathelayithi kanye nokudluliswa kwesignali eMhlabeni, kodwa akekho owayelindele ukucasha okungaka ukuthi kube i-inthanethi yeselula ye-4G eyayizoba isixhumanisi esibuthakathaka.
Futhi hhayi ehlane elithile, kodwa hhayi kude nePereslavl-Zalessky, endaweni, ngokusho kwemephu ye-MTS ne-MegaFon, ihlanganiswe kahle ne-4G. Ku-MCC yethu yeselula bekunerutha eyinkimbinkimbi ye-Kroks ap-205m1-4gx2h, lapho kufakwa khona ama-SIM khadi amabili, futhi obekufanele ifinyeze ithrafikhi kuwo ukuze sikwazi ukusakaza ividiyo ngokugcwele ku-inthanethi. Saze safaka izimpondo zephaneli zangaphandle ngenzuzo engu-18 dB. Kodwa lolu hlobo lwe-hardware lusebenze ngokunengekayo. Isevisi yokusekela i-Kroks ingaseluleka kuphela ukuthi silayishe i-firmware yakamuva, kodwa lokhu akuzange kusize, futhi isivinini samakhadi amabili e-SIM e-4G saba sibi kakhulu kunejubane le-SIM khadi kumodemu ye-USB evamile. Ngakho-ke, uma ungangitshela ukuthi iyiphi ingxenye yehadiwe engcono ukuhlela ukudluliswa kwedatha ngokuhlanganisa iziteshi ze-4G ngokuzayo, bhala kumazwana.
Izibalo zethu zomkhondo zibonakale zinembe impela; azikho izimanga. Saba nenhlanhla, ibhaluni le-stratospheric lahlala emhlabathini othambile we-peat 10 amamitha ukusuka endaweni yokugcina amanzi kanye namakhilomitha angama-70 ukusuka endaweni yokwethulwa. Igrafu yebanga le-GPS:
Futhi yile ndlela isivinini sendiza esime mpo sebhaluni ye-stratospheric esishintshe ngayo:
Yiqiniso, eyodwa yalezi zibonisi ezimbili ayizange isinde ekufikeni (yebo, bekukhona okubili, njengamakhamera we-GoPro; ukuphindaphinda kuyindlela enhle yokwandisa ukwethembeka); kuvidiyo ungabona ukuthi kuhambe kanjani ngemigqa futhi kwaphenduka. icishiwe. Kodwa zonke ezinye izinto zokusebenza zasinda ekufikeni ngaphandle kwezinkinga.
Iziphetho ngokuhlolwa kanye nekhwalithi yokuxhumana kwe-inthanethi.
Indlela iseva esebenza ngayo ibukeka kanje: ekhasini lokufikela ungathumela imilayezo yombhalo kuseva usebenzisa ifomu. Zadluliselwa ngephrothokholi ye-HTTP ngezinhlelo zokuxhumana zesathelayithi ezizimele ezi-2 kukhompyutha emiswe ngaphansi kwebhaluni le-stratospheric, futhi yadlulisela le datha eMhlabeni, kodwa hhayi ngendlela efanayo ngesathelayithi, kodwa ngesiteshi somsakazo. Ngakho-ke, saqonda ukuthi iseva ngokuvamile ithola idatha, nokuthi ingasabalalisa i-inthanethi kusuka ku-stratosphere. Ekhasini lokubikezela elifanayo, ishejuli yendiza yebhaluni ye-stratospheric yaboniswa, futhi amaphuzu okwamukela umlayezo wakho ngamunye amakwe kuyo. Okusho ukuthi, ungakwazi ukulandelela umzila nokuphakama "kweseva ephezulu kakhulu" ngesikhathi sangempela.
Sekukonke, ababambiqhaza bethu bathumele imiyalezo eyi-166 ukusuka ekhasini lokufika, lapho i-125 (75%) ilethwe ngempumelelo kuseva. Ibanga lokulibaziseka phakathi kokuthumela nokwamukela lalilikhulu kakhulu, ukusuka kumasekhondi angu-0 kuye kwangu-59 (isilinganiso sokulibaziseka amasekhondi angu-32).
Asitholanga ukuhlobana okubonakalayo phakathi kobude neleveli yokubambezeleka:
Kusukela kule grafu kuyacaca ukuthi izinga lokulibaziseka alizange lincike nganoma iyiphi indlela ebangeni elisuka endaweni yokuqalisa, okungukuthi, sithumele imilayezo yakho ngokwethembeka ngamasathelayithi, hhayi ukusuka phansi:
Isiphetho esiyinhloko esivela ekuhloleni kwethu ukuthi singathola futhi sisabalalise amasiginali e-inthanethi avela kumabhaluni e-stratospheric, futhi uhlelo olunjalo lunelungelo lokuba khona.
Njengoba ukhumbula, sathembisa ukuqhathanisa ukuxhumana kwe-Iridium ne-GlobalStar (asikaze sithole imodemu yesilayezi ngesikhathi). Ukuzinza komsebenzi wabo ezindaweni zethu kucishe kufane. Ngaphezu kwamafu indawo yokwamukela izivakashi izinzile. Kuyadabukisa ukuthi abamele uhlelo lwasekhaya "lwe-Messenger" bahlole futhi balungiselela okuthile lapho, kodwa abazange bakwazi ukunikeza noma yini ukuze ihlolwe.
Izinhlelo zekusasa
Manje, sihlela iphrojekthi elandelayo, eyinkimbinkimbi nakakhulu. Njengamanje sisebenzela imibono eyahlukene, isibonelo, ukuthi kufanele yini sihlele ukuxhumana kwe-laser okunesivinini esikhulu phakathi kwamabhaluni amabili ase-stratospheric ukuze siwasebenzise njengabaphindayo. Ngokuzayo, sifuna ukukhulisa isibalo sezindawo zokufinyelela futhi siqinisekise isivinini soxhumano lwe-inthanethi esizinzile esingafika ku-1 Mbit/isekhondi endaweni eyi-100-150 km, ukuze ngokulandelayo siqalise izinkinga zokudlulisa ividiyo eku-inthanethi ku-inthanethi. ngeke lisavuka.
