Makampani olumikizirana ndi laser akukula mofulumira ndipo atsala pang'ono kulowa mu nthawi yagolide ya chitukuko

Kulankhulana ndi laser ndi mtundu wa njira yolumikizirana pogwiritsa ntchito laser potumiza uthenga. Laser ndi mtundu watsopano wagwero la kuwala, yomwe ili ndi mawonekedwe a kuwala kwakukulu, chitsogozo champhamvu, monochromism yabwino komanso mgwirizano wamphamvu. Malinga ndi njira yosiyana yotumizira, imatha kugawidwa m'magulu a atmospherickulankhulana kwa laserndi kulumikizana kwa ulusi wa kuwala. Kulankhulana kwa laser ya mlengalenga ndi kulumikizana kwa laser pogwiritsa ntchito mlengalenga ngati njira yotumizira mauthenga. Kulankhulana kwa ulusi wa kuwala ndi njira yolumikizirana pogwiritsa ntchito ulusi wa kuwala potumiza zizindikiro za kuwala.

Dongosolo lolumikizirana ndi laser lili ndi magawo awiri: kutumiza ndi kulandira. Gawo lotumizira makamaka limapangidwa ndi laser, Optical modulator ndi optical transmitter antenna. Gawo lolandira makamaka limapangidwa ndi optical receiving antenna, optical filter ndiChowunikira zithunziChidziwitso chomwe chiyenera kutumizidwa chimatumizidwa kwaChowongolera kuwalayolumikizidwa ndi laser, yomwe imasintha chidziwitso palaserndipo imatumiza kudzera mu antenna yotumizira kuwala. Kumapeto kwa kulandira, antenna yolandira kuwala imalandira chizindikiro cha laser ndikuchitumiza kuchowunikira cha kuwala, zomwe zimasintha chizindikiro cha laser kukhala chizindikiro chamagetsi ndikuchisintha kukhala chidziwitso choyambirira pambuyo pokulitsa ndi kuwononga.

Satelaiti iliyonse yomwe ili mu netiweki ya satellite yolumikizirana ya Pentagon yomwe ikukonzekera ikhoza kukhala ndi maulalo anayi a laser kuti athe kulumikizana ndi ma satelaiti ena, ndege, zombo ndi malo oimikapo ndege.Maulalo owonekaPakati pa ma satellite ndikofunikira kwambiri kuti gulu lankhondo la US lozungulira dziko lapansi lipambane, lomwe lidzagwiritsidwa ntchito polumikizirana deta pakati pa mapulaneti angapo. Ma laser amatha kupereka kuchuluka kwa data yotumizira deta kuposa kulumikizana kwachikhalidwe kwa RF, komanso ndi okwera mtengo kwambiri.

Posachedwapa asilikali aku US apereka mapangano pafupifupi $1.8 biliyoni a pulogalamu ya 126 Constellation yomwe imangidwe padera ndi makampani aku US omwe apanga ukadaulo wolumikizirana wa optical wa one-to-many kuti utumize ma point-to-multipoint womwe ungathandize kuchepetsa mtengo womanga gulu la nyenyezi pochepetsa kwambiri kufunikira kwa ma terminal. Kulumikizana kwa optical-to-many kumachitika ndi chipangizo chotchedwa managed optical communication array (MOCA mwachidule), chomwe ndi chapadera chifukwa ndi cha modular kwambiri, ndipo gulu lolumikizirana la optical la MOCA managed optical limalola maulalo a optical inter-satellite kuti alumikizane ndi ma satellite ena ambiri. Mu kulumikizana kwachikhalidwe kwa laser, chilichonse chimakhala cha point-to-point, ubale wa optical-to-one. Ndi MOCA, ulalo wa optical wa inter-satellite ungalankhule ndi ma satellite 40 osiyanasiyana. Ukadaulo uwu si phindu lokha lochepetsa mtengo womanga magulu a nyenyezi a satellite, ngati mtengo wa ma node wachepetsedwa, pali mwayi wokhazikitsa mapangidwe osiyanasiyana a netiweki motero milingo yosiyanasiyana yautumiki.

Kalekale, satelayiti ya Beidou yaku China idachita kafukufuku wokhudza kulumikizana ndi laser, ndipo idatumiza bwino chizindikirocho mu mawonekedwe a laser kupita ku siteshoni yolandirira pansi, zomwe ndizofunikira kwambiri pakulankhulana mwachangu pakati pa ma network a satelayiti mtsogolo, kugwiritsa ntchito kulumikizana ndi laser kungathandize satelayiti kutumiza ma megabits zikwizikwi a deta pa sekondi, liwiro lathu lotsitsa tsiku ndi tsiku ndi ma megabits ochepa mpaka ma megabits khumi pa sekondi, ndipo kulumikizana ndi laser kukachitika, liwiro lotsitsa limatha kufika ma gigabytes angapo pa sekondi, ndipo mtsogolo limatha kupangidwa kukhala ma terabytes.

Pakadali pano, njira yoyendetsera maulendo ya Beidou ku China yasayina mapangano ogwirizana ndi mayiko 137 padziko lonse lapansi, ili ndi mphamvu inayake padziko lonse lapansi, ndipo ipitiliza kukula mtsogolo, ngakhale kuti njira yoyendetsera maulendo ya Beidou ku China ndi yachitatu mwa njira zoyendetsera maulendo a satellite okhwima, koma ili ndi ma satellite ambiri, kuposa kuchuluka kwa ma satellite a GPS. Pakadali pano, njira yoyendetsera maulendo ya Beidou imagwira ntchito yofunika kwambiri m'gulu lankhondo komanso m'gulu la anthu wamba. Ngati kulumikizana ndi laser kungatheke, kudzabweretsa uthenga wabwino padziko lonse lapansi.
