ʻApōpō e hoʻouna ana mākou i kā mākou kikowaena i ka stratosphere. I ka wā o ka lele ʻana, e hāʻawi ka baluna i ke komo pūnaewele, hopu a hoʻouna i nā wikiō a me nā ʻikepili telemetry i ka Honua. Ua kākau mākou i nā manawa he nui e kaʻana like ana mākou i nā kikoʻī loea o kā mākou papahana "Space Data Center" (i ʻike mua ʻia ʻo ""). Ua hoʻohiki mākou—ke mālama nei mākou! Aia ma lalo o ke ʻoki he mau lako a me ke code.
kikowaena pūnaewele
ʻOiai ma ka papahana "Server in the Clouds" ma mua, i ko mākou piʻi ʻana i loko o kahi baluna ea wela piha me kahi poʻe hana ʻelua, ʻo ka lawe ʻana i kahi kikowaena piha me kahi pākaukau he mea kūpono ʻole ia. A i kēia manawa ke kamaʻilio nei mākou e pili ana i kahi baluna stratospheric liʻiliʻi e piʻi i 30 km ma kahi o 1. No laila, ua koho mākou i ka Raspberry Pi like me ke kikowaena pūnaewele. E hoʻopuka kēia microcomputer i kahi ʻaoʻao HTML a hōʻike iā ia ma kahi hōʻike ʻokoʻa.
Hoʻohui Satellite
Ma waho aʻe o ka Raspberry Pi, e kau ʻia nā modem mai nā pūnaewele kamaʻilio ukali ʻo Iridium a me Globalstar ma luna o ka moku. E like me kāu e hoʻomanaʻo nei, ua hoʻolālā mākou e hoʻohui i kahi modem mai ka pūnaewele Gonets kūloko i ko lākou mau kūlana, akā ʻaʻole i loaʻa iā mākou ka manawa e loaʻa ai i ka manawa kūpono, no laila e hoʻouna mākou iā ia ma ka mokulele aʻe. E loaʻa i ka kikowaena pūnaewele kāu mau leka ma o nā modem ukali, hiki ke hoʻouna ʻia i E hoʻouna ʻia kēia mau leka i ka Raspberry Pi, nāna e hoʻonohonoho iā lākou a hōʻike iā lākou ma kahi ʻaoʻao HTML.
He mea nui: ʻO ka palena lōʻihi no nā leka kikokikona ma ka ʻōlelo Lūkini he 58 mau huapalapala (me nā hakahaka). Inā ʻoi aku ka lōʻihi o ka leka, e ʻoki ʻia ia i ka wā e hoʻouna ʻia ai. E wehe ʻia nā huapalapala kūikawā a pau mai ka kikokikona, e like me: /+$%&;''""<>n a me nā mea like.
ʻOiai hoʻokahi wale nō awa UART o ka Raspberry Pi, e hoʻohui mākou i nā modem satellite ma o kahi kikowaena waena, nāna e hōʻiliʻili i ka ʻikepili mai nā modem a hoʻouna aku i ka Raspberry Pi.
Modem lekiō
ʻAʻole wale ka kikowaena pūnaewele e hōʻike i nā leka āpau i loaʻa mai iā ʻoe ma ka pale akā e hoʻouna pū iā lākou i ka Honua ma o kahi modem lekiō LoRa. Penei mākou e makemake ai e hoʻāʻo i ka manaʻo o ka hāʻawi ʻana i ka pūnaewele mai ka stratosphere (he hoʻohanohano i ka papahana Google Loon). ʻOiaʻiʻo, ʻaʻole ʻo kā mākou baluna stratospheric he repeater kamaʻilio piha, akā inā lawa kona mau hiki no ka hoʻoili ʻikepili paʻa me ka ʻole o ka nalowale nui o ka ʻikepili, e hiki nō i nā ʻōnaehana kūikawā ke lawelawe i ka hāʻawi pūnaewele mai ka pre-space.
Telemetry
Hoʻolālā pū mākou e hōʻike i ka ʻikepili telemetry ma ka ʻaoʻao HTML like. E loaʻa i ka Raspberry Pi ia mai kahi mea hoʻokele lele kaʻawale.
Hoʻokolokolo ia i nā ʻano mea ʻike like ʻole, hiki ke waiho ʻia i loko a ma waho o ka pā lako, hōʻiliʻili i ka ʻikepili, hoʻonohonoho iā ia, a hāʻawi iā ia i kahi ʻano kūpono i ka poʻe e noi ana. I ko mākou hihia, e noi ia i kahi Raspberry Pi. E hoʻopaʻa mākou i ke kaomi, ke kiʻekiʻe, nā hoʻonohonoho GPS, ka wikiwiki kū a me ka pae, a me ka mahana.
Hoʻouna ʻia ka ʻikepili mai ka mea hoʻokele lele ma nā kaula lōʻihi, a laila e hana ʻia me ka hoʻohana ʻana i kēia code:
$str = 'N:647;T:10m55s;MP.Stage:0;MP.Alt:49;MP.VSpeed:0.0;MP.AvgVSpeed:0.0;Baro.Press:1007.06;Baro.Alt:50;Baro.Temp:35.93;GPS.Coord:N56d43m23s,E37d55m68s;GPS.Home:N56d43m23s,E37d55m68s;Dst:5;GPS.HSpeed:0;GPS.Course:357;GPS.Time:11h17m40s;GPS.Date:30.07.2018;DS.Temp:[fc]=33.56;Volt:5.19,0.00,0.00,0.00,0.00,0.00,0.00,0.00';
parse_str(strtr($str, [
':' => '=',
';' => '&'
]), $result);
print_r($result);ua hoʻololi ʻia i loko o kahi array i kahi ʻano kūpono no ka hōʻike ʻana:

)E hoʻouna pū mākou i ka ʻikepili telemetry i ka Honua me kāu mau leka. No kēia kumu, e hoʻonohonoho mākou i kahi kikowaena loaʻa ma kahi hoʻokuʻu.
Hōʻike a me ke kāmela
I mea e hōʻoia ai e loaʻa ana i ke kikowaena kāu mau leka ma o ka satelite, a aia maoli nō ia ma ka stratosphere a ʻaʻole wale nō e waiho ana i loko o ko mākou keʻena, ua hoʻoholo mākou e hōʻike i nā leka telemetry āpau ma kahi hōʻike i hopu ʻia e kahi GoPro. He liʻiliʻi ko mākou manawa e hoʻomākaukau ai i ka papahana (a i ka manawa hea e lawa ai ka manawa?!), no laila ua haʻalele mākou i ka hoʻoluhi o AliExpress a me kahi hao hao, a koho i kahi mea hana i hana mua ʻia. Ua lawa ia no kā mākou mau pono. E hoʻopili mākou i ka hōʻike i ka Raspberry Pi ma o HDMI.
Hoʻolālā pū mākou e hoʻolaha i ke wikiō mai ka GoPro ma o kahi kahawai lekiō ʻokoʻa, akā ʻaʻole ʻike ʻia pehea e hana ai—hiki i ka uhi ao haʻahaʻa ke hōʻemi nui i ka laulā kamaʻilio. I kēlā me kēia hihia, ma hope o ko mākou ʻike ʻana i ka pōpō i pae ʻia, e kau mākou i ke wikiō mai ke kāmela, a hiki iā ʻoe ke ʻike ponoʻī i nā leka i loaʻa i kā mākou "kikowaena ʻikepili pre-space" a me ke kiʻekiʻe o kona hiki ʻana—e hōʻike ʻia ka telemetry ma ka ʻaoʻao HTML like, a e ʻike ʻia kahi ʻāpana o ka ʻaoʻao o ka honua.
Ka lako
E hoʻohana ʻia kēia mau mea nani a pau e kahi pākahi lithium 3S4B—ʻekolu ma ke ʻano moʻo a ʻehā ma ke ʻano like. ʻO ka nui o ka mana ma kahi o 14 Ah ma 12 V. Manaʻo mākou ua lawa kēia, akā ma hope o ka ʻākoakoa hope loa, e ana mākou i ka hoʻohana maoli ʻana a hoʻohui i nā pākahi hou aʻe inā pono.
E hoʻohui i kēia mau mea hoʻailona GPS a pau, a mākou e hoʻohana ai e ʻimi i ka baluna i pae. A e lawelawe ka pā hermetic ma ke ʻano he "home" no ke kikowaena a me nā lako ʻē aʻe.
E pale aku ia i nā lako palupalu mai nā loli o ka mahana a me ke kaomi. E hōʻemi pū ia i ka nui o ka radiation, ʻoiai ʻaʻole pili kēia no kā mākou papahana; ʻaʻole e lele ka kikowaena ma ka stratosphere no ka manawa lōʻihi, a ʻaʻole kiʻekiʻe ka radiation hope ma laila e like me ka ISS.
Ma waho aʻe o ka hoʻouna ʻana i nā leka i , hiki iā ʻoe ke komo i kahi hoʻokūkū a kuhi i kahi pae o ka probe. ʻO ka makana nui he huakaʻi i Baikonur no ka hoʻokuʻu ʻana i ka mokulele Soyuz-MS-13.
