Re ile ra ngola ka makhetlo a 'maloa hore re tla bua ka lehlakore la tekheniki la morero oa rona "Space Data Center" (eo pele e neng e arabela lebitsong""). Re tšepisitse - re tla fana! Tlas'a sehiloeng ho na le likotoana tse seng kae tsa hardware le khoutu.
Seva ea webo
Esita le morerong o fetileng oa "Server in the Clouds", ha re nyolohela ka balune e tletseng ka botlalo re e-na le sehlopha sa batho ba babeli, re nka le rona seva se feletseng se nang le kopano ea betri e ne e le, ha re re, ha re nahane. 'Me hona joale re bua ka balune e nyenyane ea stratospheric, e tla tlameha ho hloa lik'hilomithara tse 30, eseng 1. Ka hona, re khethile Raspberry Pi e tšoanang le seva sa websaete. Microcomputer ena e tla hlahisa leqephe la HTML ebe e le hlahisa ponts'ong e arohaneng.
Khokahano ea satellite
Ho phaella ho Raspberry, li-modem tse tsoang ho Iridium le Globalstar li-network tsa puisano tsa satellite li tla fofa ka sekepeng. Joalo ka ha u hopola, re ne re rerile ho eketsa modem bakeng sa marang-rang a Gonets a lehae k'hamphaning ea bona, empa re ne re sena nako ea ho e amohela esale pele, kahoo re tla e romella sefofaneng se latelang. Ka li-modem tsa sathelaete, seva sa marang-rang se tla amohela melaetsa ea hau, e ka romelloang ho . Melaetsa ena e tla fetisetsoa ho Raspberry Pi, e tla e beha meleng le ho e hlahisa leqepheng la HTML.
Ntlha ea bohlokoa: moeli oa bolelele ba molaetsa oa mongolo ka Serussia ke litlhaku tse 58 (ho kenyeletsoa le libaka). Haeba molaetsa o le molelele, o tla khaoloa nakong ea phetiso. Hape, litlhaku tsohle tse ikhethileng li tla khaoloa ho tsoa temaneng, mohlala, /+$%&;''""<>n le tse ling tse joalo.
Kaha Raspberry Pi e na le kou e le 'ngoe feela ea UART, re tla hokahanya li-modem tsa sathelaete ka hub e bohareng, e tla bokella data ho tsoa ho modem ebe e e romella ho Raspberry Pi.

Seva ea marang-rang e ke ke ea hlahisa feela melaetsa eohle e amohetsoeng ho uena skrineng, empa hape e tla e fetisetsa Lefatšeng ka modem ea radio ea LoRa. Kahoo re batla ho leka mohopolo oa ho tsamaisa Marang-rang ho tsoa ho stratosphere (sethabathaba ho projeke ea Google Loon). Ha e le hantle, balune ea rona ea stratospheric ha e bue ka mokhoa o feletseng oa puisano, empa le haeba bokhoni ba eona bo lekaneng bakeng sa phetiso ea data e tsitsitseng, ntle le tahlehelo e kholo ea tlhahisoleseding, joale mekhoa e khethehileng e tla sebetsana ka katleho le ho aba Inthanete ho tloha pele ho sebaka.
Telemetry
Ho phaella moo, re rera ho hlahisa lintlha tsa telemetry leqepheng le tšoanang la HTML. Raspberry Pi e tla li nka ho tsoa ho molaoli ea fapaneng oa sefofane.
E hlahloba li-sensor tse fapaneng tse ka beoang kahare le kantle ho lebokose la hermetic ea Hardware, e bokella tlhahisoleseling ka qubu, ea e kopanya ebe e e fa ba e botsang ka mokhoa o loketseng. Tabeng ea rona, e tla kopa Raspberry Pi. Re tla rekota khatello, bophahamo, likhokahano tsa GPS, lebelo le otlolohileng le mocheso le mocheso.
