S\u00f5brad, oleme v\u00e4lja m\u00f5elnud uue \u00fcrituse. Paljud teist m\u00e4letavad meie eelmisel aastal toimunud l\u00f5busat geeniuseprojekti \"Server pilvedes<\/a><\/noindex>\": me tegime v\u00e4ikese serveri Raspberry Pi p\u00f5hjal ja lasime selle \u00f5hupalliga \u00f5hku. <\/p>\n

\"Server<\/a><\/noindex><\/p>\n

N\u00fc\u00fcd oleme otsustanud minna veel kaugemale, t\u00f5en\u00e4oliselt k\u00f5rgemale \u2014 meid ootab stratosf\u00e4\u00e4r!
\n<\/a><\/noindex>
\nKoheselt meenutame, mis oli esimese projekti \"Server pilvedes\" sisu. Server ei lennanud lihtsalt \u00f5hupalliga, p\u00f5nevuseks oli, et seade t\u00f6\u00f6tas ja edastas maapinnale oma telemeetria. <\/p>\n

\"Server
\n
\nSee t\u00e4hendab, et k\u00f5ik soovijad said reaalajas j\u00e4lgida liikumisteed. Enne starti m\u00e4rkis 480 inimest kaardile punktid, kuhu \u00f5hupall v\u00f5iks maanduda.<\/p>\n

\"Server
\n
\nKuna Edward Murphy seadusele vastavalt, kadus lennu ajal p\u00f5hiline sideteenus GSM-modemi kaudu. Seet\u00f5ttu pidi meeskond s\u00f5na otseses m\u00f5ttes lennu ajal l\u00fclituma varuside peale, mis p\u00f5hines LoRa<\/a><\/noindex>. Samuti pidid \u00f5hupallijuhid lahendama probleemi USB-kaabliga, mis \u00fchendas telemeetria mooduli ja Raspberry 3 \u2014 tundub, et see kartsid k\u00f5rgust ja keeldus t\u00f6\u00f6tamast. \u00d5nneks selle seadme probleemid ka j\u00e4idki. \u00d5hupall maandus \u00f5nnelikult. Kolm \u00f5nnelikku, kelle m\u00e4rgid asusid k\u00f5ige l\u00e4hemal maandumispaigale, said maitsvaid auhindu. \u00dctlemata, et esimese koha v\u00f5itjaks oli osalemine AFR 2018 purjetamisv\u00f5istlusel (Tere, Vitalik!). <\/p>\n

Projekt t\u00f5estas, et idee \"\u00f5hup\u00f5hisest serverist\" pole sugugi nii hull nagu v\u00f5iks arvata. Ja me tahame teha j\u00e4rgmise sammu teel \"lennuv\u00e4ljade andmekeskusse\": kontrollida serveri t\u00f6\u00f6d stratosf\u00e4\u00e4ris stratosf\u00e4\u00e4rilennuki abil, mis t\u00f5useb umbes 30 km k\u00f5rgusele \u2014 stratosf\u00e4\u00e4ri. K\u00e4ivitame selle kosmonautika p\u00e4evaks, seega on aega j\u00e4\u00e4nud v\u00e4ga v\u00e4he, v\u00e4hem kui kuu. <\/p>\n

Nimi \"Server pilvedes 2.0\" pole t\u00e4iesti adekvaatne, kuna sellisel k\u00f5rgusel ei kohta sa \u00fchtegi pilve. Seet\u00f5ttu v\u00f5iks projekti nimetada \"\u00dcksnes pilvedest k\u00f5rgem server\" (j\u00e4rgmine projekt tuleb nimetada \"Kallis, sa oled kosmos!\").<\/p>\n

\"Server
\n
\nNagu esimese projekti puhul, on server toimiv. Kuid erip\u00e4ra on teistsugune: me tahame testida Google Loon'i kuulsat kontseptsiooni ja testida interneti edastamise v\u00f5imalust stratosf\u00e4\u00e4rist.<\/p>\n

Serveri t\u00f6\u00f6p\u00f5him\u00f5te on j\u00e4rgmine: maandumislehe kaudu saate saata serverisse teksts\u00f5numeid. Need edastatakse HTTP-protokolli kaudu kahe s\u00f5ltumatu satelliitside s\u00fcsteemi abil stratosf\u00e4\u00e4ri all riputatavale arvutile, mis edastab need andmed tagasi Maale mitte sama teed pidi, vaid raadiokanali kaudu. Nii saame teada, et server \u00fcldse saab andmeid ja et ta suudab jagada internetti stratosf\u00e4\u00e4rist. Samuti suudame aru saada, kui suur on teel kadunud teabe protsent. Samal maandumislehel kuvatakse stratosf\u00e4\u00e4ri lennugraafik, kus on t\u00e4histatud iga teie saadetud s\u00f5numi vastuv\u00f5tu punktid. See t\u00e4hendab, et saate reaalajas j\u00e4lgida \"\u00fcle pilvede oleva serveri\" marsruuti ja k\u00f5rgust.<\/p>\n

Ja neile, kes t\u00e4ielikult ei usu ja \u00fctlevad, et see on k\u00f5ik kokku lepitud, paigaldame pardale v\u00e4ikese ekraani, kus HTML-lehel kuvatakse k\u00f5ik teie saadetud s\u00f5numid. Ekraanile teeb pilti kaamera, mille vaatev\u00e4ljas on ka osa horizonta. Tahame edastada videosignaali raadiokanali kaudu, kuid siin on n\u00fcanss: kui ilm on hea, siis peaks video j\u00f5udma maani enamiku stratosf\u00e4\u00e4ri lennu jooksul, 70\u2013100 km k\u00f5rgusel. Pilvisuse korral v\u00f5ib edastamise kaugus langeda 20 km-ni. Kuid igal juhul salvestatakse video ja me avaldame selle p\u00e4rast seda, kui leiame kukkunud stratosf\u00e4\u00e4ri. \u00dctlen veel, et me otsime seda pardal oleva GPS-saatja signaali j\u00e4rgi. Statistika kohaselt maandub server 150 km raadiuses laskmispaigast.<\/p>\n

Peagi r\u00e4\u00e4gime p\u00f5hjalikult, kuidas stratosf\u00e4\u00e4ri kasulik koormus on \u00fcles ehitatud ja kuidas k\u00f5ik need komponendid omavahel t\u00f6\u00f6tama peaksid. Samuti paljastame veel m\u00f5ned huvitavad projekti detailid, mis on seotud kosmosega. <\/p>\n

Kuna teil oleks huvitav j\u00e4lgida projekti, nagu eelmisel aastal, oleme v\u00e4lja m\u00f5elnud konkursi, kus tuleb m\u00e4\u00e4rata serveri maandumiskoht. V\u00f5itja, kes k\u00f5ige t\u00e4psemalt piisavaid ennustusi teeb, saab minna Baikonuri, et j\u00e4lgida mehitamata kosmoselaeva \u201eSoyuz MS-13\u201d starti 6. juulil; teise koha auhind on reisitunnistus meie s\u00f5pradelt Tut.ru. Kaksk\u00fcmmend muud osalejat saavad minna grupiekskursioonile T\u00e4helinna mais. Lisainfot leiate konkursi veebisaidilt<\/a><\/noindex>.<\/p>\n
