Nws tau npaj yuav tshaj tawm 12 satellites nyob rau hauv 2021 kom ua tiav Zero Breakthrough hauv Laser Kev Sib Txuas Lus ntawm Lub Ntiaj Teb satellite Constellation ntawm Internet ntawm Yam
Kawm los ntawm Tuam Tshoj Aerospace Science thiab kev lag luam pab pawg hais tias huab cua project Tam sim no, theem kev tsim kho tau pib. Nws tau npaj yuav tshaj tawm 12 satellites hauv 2021. Lub sijhawm ntawd, lub ntiaj teb kev pabcuam muaj peev xwm ntawm qhov chaw hauv Is Taws Nem ntawm cov khoom yuav ua tau zoo dua qub.Xingyun project yog thawj qhov qis qis qis-band Internet ntawm cov khoom satellite constellation ntawm nws tus kheej nqis peev thiab tsim los ntawm Tuam Tshoj Aerospace Science thiab kev lag luam pab pawg. Aerospace Sanjiang Aerospace Xingyun Technology Co., Ltd. yog lub luag haujlwm rau kev tsim kho thiab kev ua haujlwm Hauv peb theem, nws tau npaj los tsim ib lub hnub qub uas muaj 80 LEO kev sib txuas lus satellites nyob ib ncig ntawm 2023. Huab engineering tuaj yeem daws tau qhov teeb meem ntawm kev sib txuas lus qhov muag tsis pom qhov chaw uas tshwm sim los ntawm qhov tsis txaus ntawm cov kev sib txuas lus hauv av hauv av (tam sim no, thaj av npog yog kwv yees li 20%, thiab cov dej hiav txwv npog tsawg dua 5%). Hnub ua ntej nag hmo, ob- txoj kev sib txuas lus nrog ua tiav cov txheej txheem hauv tsev thiab kev ruaj ntseg telemetry tau paub txog ntawm xingyun-2 satellites 01 thiab 02, uas txhais tau hais tias lub laser kev sib txuas lus them nyiaj siv tshuab nqa los ntawm xingyun-2 satellite tau ua tiav qhov tseeb, thiab Suav Satellite Internet ntawm txhua yam constellation muaj. ua tiav qhov kev ua tiav ntawm xoom inter satellite laser kev sib txuas lus.
Inter satellite laser kev sib txuas lus yog ib txoj kev sib txuas lus uas siv laser beam ua cov cab kuj xa cov duab, suab, teeb liab thiab lwm yam ntaub ntawv nyob rau hauv qhov chaw. Nws muaj qhov zoo ntawm kev sib kis tus nqi siab, muaj zog tiv thaiv kev cuam tshuam, lub kaw lus me me davhlau ya nyob twg ntim, lub teeb yuag thiab kev siv hluav taws xob tsawg. Nws tuaj yeem txo qhov kev cia siab ntawm satellite constellation system nyob rau hauv av network, thiaj li yuav txo tau tus naj npawb thiab nqi ntawm cov chaw nres tsheb hauv av, nthuav cov kev pab them nqi thiab paub txog kev ntsuas thoob ntiaj teb thiab kev tswj xyuas. Nws tau tshaj tawm tias kev sib txuas lus laser thauj khoom loj ntawm xingyun-2 satellites 01 thiab 02 yog 6.5kg, thiab lub zog siv hluav taws xob yog 80W.
Tam sim no, inter satellite laser txuas tshuab tau dhau los ua cov thev naus laus zis tseem ceeb hauv kev txhim kho thoob ntiaj teb kev sib txuas lus satellite. Cov ntaub ntawv pej xeem qhia tau hais tias ntawm cov phiaj xwm hauv ntiaj teb qis thiab nruab nrab orbit constellation, tsuas yog Starlink constellation thiab LEOSAT constellation ntawm Tebchaws Meskas tau tshaj tawm txoj kev npaj siv inter satellite laser txuas kom paub qhov chaw sib txuas. Nyob rau hauv Suav teb, Xingyun tuam txhab tau tsim qhov tsawg tshaj plaws inter satellite laser kev sib txuas lus load nyob rau hauv Tuam Tshoj, ua tiav ib tug breakthrough nyob rau hauv lub xoom laser kev sib txuas lus ntawm domestic satellite Internet ntawm tej constellation, thiab qhib lub bottleneck ntawm cov ntaub ntawv kis tau tus mob ntawm Satellite Internet ntawm tej yam constellations.
