Zvikamu zveKutaurirana neLaser Yepamusoro-soro & Zviteshi

Zvikamu zvekukurukurirana neLaser zvinomhanya zvakanyanya & materminals Mufananidzo wakaratidzwa

Tsananguro pfupi:

Yakavakirwa kutaurirana kwesatellite yechizvarwa chinotevera, mhuri iyi yezvikamu zvekutaurirana nelaser uye materminals inoshandisa kubatanidzwa kwepamusoro kwe opto-mechanical uye tekinoroji yelaser iri pedyo ne infrared kuti ipe zvinongedzo zvinokurumidza uye zvakavimbika zvekutaurirana pakati pesatellite uye kubva pasi kuenda pasi.

Pfupiso

Zvichienzaniswa nemaitiro eRF echinyakare, kutaurirana nelaser kunopa bandwidth yakakwira zvakanyanya, kushandiswa kwesimba kwakaderera, uye kudzivirira kupindira uye kuchengetedzeka kwakanyanya. Yakakodzera zvakanaka mapoka makuru enyeredzi, kuongorora Pasi, kuongorora nzvimbo yakadzika, uye kutaurirana kwakachengeteka/kwakawanda.

Chikamu ichi chinosanganisira ma "high-precision optical assemblies", ma "inter-satellite" uye "satellite-to-ground laser terminals", uye system yakakwana yekuedza yakaenzana ne "ground far-field" - ichigadzira mhinduro yakakwana kubva kumagumo kuenda kumagumo.

Zvigadzirwa Zvikuru & Magadzirirwo

D100 mm Opto-Mechanical Assembly

Aperture Yakajeka:100.5 mm
Kukura:14.82×
Munda weMaonero:±1.2 mrad
Angle yeOptical Axis yeChiitiko-Kubuda:90° (kugadzika kwemunda we zero)
Dhayamita Yekubuda Mudzidzi:6.78 mm
Zvinonyanya kukosha:
Dhizaini yemaziso yakanyatsogadzirwa inochengetedza kukwirira kwemwaranzi uye kugadzikana kwakanaka panguva refu.
Kurongeka kwe90° optical-axis kunogadzirisa nzira uye kunoderedza vhoriyamu yesystem.
Maumbirwo akasimba uye zvinhu zvepamusoro zvinopa simba rakasimba rekudzivirira kutenderera uye kugadzikana kwekupisa kuti zvishande mukati memhepo.

Chiteshi Chekutaurirana neLaser cheD60 mm

Mwero weData:100 Mbps divi rimwe nerimwe @ 5,000 km
Rudzi rweChinongedzo:Pakati pesetiraiti
Aperture:60 mm
Kurema:~7 kg
Kushandiswa kweSimba:~34 W
Zvinonyanya kukosha:Dhizaini diki, ine simba shoma yemapuratifomu madiki asi ichichengetedza kuvimbika kwepamusoro.

Chiteshi Chekutaurirana neLaser Chinotenderera Nekutenderera

Mwero weData:10 Gbps divi rimwe nerimwe @ 3,000 km
Mhando dzeZvisungo:Pakati pesatellite nesatellite-kune-pasi
Aperture:60 mm
Kurema:~6 kg
Zvinonyanya kukosha:Kuburitswa kweMulti-Gbps kwekudzikira kukuru kwedata uye network yepakati pemapoka enyeredzi; kuwana nekutevera nemazvo kunoita kuti kubatana kugare kwakasimba kana munhu achifamba zvakanyanya.

Chiteshi Chekutaurirana cheLaser cheCo-Orbit

Mwero weData:10 Mbps divi rimwe nerimwe @ 5,000 km
Mhando dzeZvisungo:Pakati pesatellite nesatellite-kune-pasi
Aperture:60 mm
Kurema:~5 kg
Zvinonyanya kukosha:Yakagadzirirwa kutaurirana mundege imwe chete; yakareruka uye ine simba shoma pakushandiswa kwemapoka enyeredzi.

Sisitimu Yekuyedza Yakaenzana neLaser yeSatellite Ground Far-Field

Chinangwa:Inotevedzera uye inoongorora mashandiro esatellite laser link pasi.
Zvakanakira:
Kuedzwa kwakazara kwekugadzikana kwedanda, kushanda zvakanaka kwelink, uye maitiro ekupisa.
Inoderedza njodzi yekutenderera kwendege uye inowedzera kuvimbika kwendege isati yatanga.

Matekinoroji eCore & Mabhenefiti

Kutumira Kwemagetsi Kunomhanya Nekukurumidza, Kukwanisa Kukuru:Kuwanda kwedata rinosvika pamatanho maviri kusvika ku10 Gbps kunoita kuti pave nekukasira kudhonzwa kwemifananidzo ine resolution yepamusoro uye data resainzi rinosvika panguva chaiyo.
Simba Rakareruka uye Rakaderera:Huremu hwemuchina wekupedzisira hwe5–7 kg ne ~34 W simba rekudhonza rinoderedza mutoro wekutakura zvinhu uye rinoita kuti basa riwedzere.
Kunongedza Kwakanyatsonaka uye Kugadzikana:±1.2 mrad field of view uye dhizaini ye90° optical-axis inopa kunyatsojeka kwekunongedza uye kugadzikana kwemwaranzi pakati pemalink emakiromita zviuru zvakawanda.
Kuenderana kweMulti-Link:Inotsigira kutaurirana pakati pesatellite nesatellite kubva pasi zvisina muganho kuti ikwanise kushandura zvakanyanya basa rayo.
Kusimbiswa Kwepasi Kwakasimba:Sisitimu yekuyedza yefar-field yakatsaurirwa inopa simulation yakazara uye kusimbiswa kwekuvimbika kwakanyanya pakutenderera kwemhepo.

Minda Yekushandisa

Kubatana kweSatellite Constellation:Kuchinjana kwedata re bandwidth yepamusoro pakati pesatellite kune mashandiro akarongeka.
Kucherechedza Nyika & Kuona Zviri Kure:Kukurumidza kudzikiswa kwedata rekutarisa rakawanda, zvichideredza mashandiro ekugadzirisa.
Kuongorora Nzvimbo Dzakadzika:Kutaurirana kuri kure, kunomhanya zvakanyanya, kwekuenda kumwedzi, kuMars, nedzimwe nzvimbo dzemuchadenga dzakadzika.
Kutaurirana Kwakachengeteka uye Kwehuwandu:Kutapurirana kwemhepo ine mwenje mutete hakudi kuteererwa nenzeve uye kunotsigira QKD nedzimwe nzira dzakachengeteka.
