Indasitiri yekutaurirana nelaser iri kukura nekukurumidza uye yava kuda kupinda munguva yegoridhe yekukura
Kutaurirana neLaser rudzi rwenzira yekutaurirana inoshandisa laser kutumira ruzivo. Laser rudzi rutsva rwechiedza chinobva, ine hunhu hwekupenya kwakanyanya, kutungamira kwakasimba, monochromism yakanaka uye kubatana kwakasimba. Zvichienderana ne transmission medium yakasiyana, inogona kukamurwa kuita atmospherickutaurirana nelaseruye kutaurirana nefiber ye optical. Kutaurirana ne laser yemhepo ikutaurirana ne laser uchishandisa atmosphere senzira yekutumira. Kutaurirana nefiber ye optical imodhi yekutaurirana uchishandisa fiber ye optical kutumira masaini e optical.
Sisitimu yekutaurirana nelaser ine zvikamu zviviri: kutumira nekugamuchira. Chikamu chinotumira zvinhu chinosanganisira laser, Optical modulator uye optical transmitting antenna. Chikamu chinogamuchira zvinhu chinosanganisira optical receiving antenna, optical filter uyeChinoongorora mufananidzoRuzivo rwunofanirwa kutumirwa runotumirwa kuneModulator yemazisoyakabatana nelaser, iyo inogadzirisa ruzivo ruri palaseruye inoitumira kunze kuburikidza neantenna inotumira optical. Pamugumo wekugamuchira, antenna inogamuchira optical inogamuchira chiratidzo chelaser uye inoitumira kunechinoona chemaziso, iyo inoshandura chiratidzo chelaser kuita chiratidzo chemagetsi uye inochishandura kuita ruzivo rwepakutanga mushure mekuwedzerwa uye kubviswa kwesimba.
Satellite yega yega iri muPentagon yakarongwa kuti ishandise mesh communications satellite network inogona kunge iine laser link ina kuitira kuti ikwanise kutaurirana nemamwe masatellite, ndege, ngarava nezviteshi zvepasi.Zvinongedzo zveOpticalpakati pemasetiraiti zvakakosha pakubudirira kweboka remauto eUS rinotenderera pasi peEarth orbit, iro richashandiswa pakutaurirana kwedata pakati pemapuraneti akawanda. MaLaser anogona kupa huwandu hwedata rekutumira data kupfuura kutaurirana kweRF kwechinyakare, asi anodhurawo zvakanyanya.
Mauto eUS achangobva kupa zvibvumirano zvinosvika mabhiriyoni gumi nemazana masere emadhora (1.8 bhiriyoni) zvechirongwa che126 Constellation chakavakwa zvakasiyana nemakambani ekuUS akagadzira tekinoroji yekutaurirana kwe optical ye one-to-many yekutumira ma point-to-multipoint iyo inogona kubatsira kuderedza mutengo wekuvaka nyeredzi nekuderedza zvakanyanya kudiwa kwema terminals. Kubatana kwe one-to-many kunowanikwa nemudziyo unonzi managed optical communication array (MOCA muchidimbu), iyo yakasiyana nekuti ine modular, uye MOCA managed optical communication array inogonesa optical inter-satellite links kuti dzitaurirane nemamwe ma satellite akawanda. Mukutaurirana kwe laser kwechinyakare, zvese zvinoonekwa se point-to-point, hukama hwe one-to-one. NeMOCA, inter-satellite optical link inogona kutaura nema satellite makumi mana akasiyana. Iyi tekinoroji haisi kungobatsira chete kuderedza mutengo wekuvaka satellite constellations, kana mutengo wema nodes ukaderedzwa, pane mukana wekushandisa ma network architecture akasiyana uye nekudaro mazinga ebasa akasiyana.
Kare kare, satellite yeBeidou yekuChina yakaita kuyedza kutaurirana nelaser, ikakwanisa kutumira chiratidzo ichi muchimiro chelaser kunzvimbo yekugamuchira pasi, izvo zvakakosha zvikuru pakutaurirana nekukurumidza pakati penetwork dzesatellite mune ramangwana, kushandiswa kwekutaurirana nelaser kunogona kubvumira satellite kutumira zviuru zvemamegabits edata pasekondi, kumhanya kwedu kwekutora kwezuva nezuva kuri mamegabits mashoma kusvika gumi megabits pasekondi, uye kana kutaurirana nelaser kwangozadzikiswa, kumhanya kweDownload kunogona kusvika magigabytes akati wandei pasekondi, uye mune ramangwana kunogona kutogadzirwa kuita materabytes.
Parizvino, sisitimu yekufamba nendege yeBeidou yeChina yakasaina zvibvumirano zvekushandira pamwe nenyika 137 pasi rose, ine simba guru pasi rose, uye icharamba ichikura mune ramangwana, kunyangwe sisitimu yekufamba nendege yeBeidou yeChina iri seti yechitatu yesisitimu yekufamba nendege yesatellite yakakura, asi ine huwandu hukuru hwemasatellite, kutopfuura huwandu hwemasatellite eGPS system. Parizvino, sisitimu yekufamba nendege yeBeidou inoita basa rakakosha mumunda wemauto nemumunda wevagari. Kana kutaurirana nelaser kukagona kuitika, kuchaunza mashoko akanaka pasi rose.
