Incamake

Ugereranyije na sisitemu zisanzwe za RF, itumanaho rya laser ritanga umuyoboro munini w’itumanaho, ingufu nke zikoreshwa, kandi rirwanya kubangamira no kurinda umutekano. Rikwiriye cyane inyenyeri nini, kwitegereza Isi, gushakisha mu kirere cyimbitse, ndetse no gutumanaho mu mutekano/mu buryo bunini.

Iyi porogaramu ikubiyemo uburyo bwo gukora optique bugezweho, ibyuma bya laser bihuza satellite na satellite, hamwe na sisitemu y’igerageza ingana n’iya ground far-field—ikora igisubizo cyuzuye kuva ku mpera kugeza ku mpera.

Sisitemu yo gupima Satellite Laser Link Ground Far-Field Equivalent

Intego:Igaragaza kandi ikagenzura imikorere y'umurongo wa laser ya satelite ku butaka.
Ibyiza:
Isuzuma ryimbitse ry’ubudahangarwa bw’imirasire, imikorere myiza y’urukiramende, n’imyitwarire y’ubushyuhe.
Bigabanya ibyago byo mu kirere kandi byongera icyizere cyo gukora mbere yo gutangira.

Ikoranabuhanga ry'ibanze n'ibyiza

Kohereza ubutumwa bwihuse kandi bufite ubushobozi bunini:Igipimo cy’amakuru ajyanye n’icyerekezo cy’ibiri kugeza kuri 10 Gbps gituma habaho kugabanya vuba amashusho afite ubushobozi bwo hejuru n’amakuru ajyanye n’ubumenyi mu gihe nyacyo.
Ingufu zoroheje kandi nke:Uburemere bwa terminal ya kg 5–7 hamwe n'imbaraga zirenga wati 34 bigabanya umutwaro w'umuzigo kandi bikongera igihe cyo gukora ubutumwa.
Gupima no Guhagarara neza cyane:± 1.2 mrad field of view hamwe n'igishushanyo cya optical-axis 90° bitanga icyerekezo cyiza cyane kandi bikagira umurava uhamye ku ntera ya kilometero ibihumbi byinshi.
Guhuza amahuriro menshi:Ishyigikira neza itumanaho hagati ya satelite na satelite kuva ku butaka kugira ngo yorohereze ubutumwa bwose.
Igenzura ry’ubutaka rihamye:Sisitemu yihariye yo gupima kure itanga uburyo bwo kwigana no kwemeza ko ari ingirakamaro cyane mu gihe cyo kuzenguruka.

Ahantu ho Gusaba

Imiyoboro ya Satelite Constellation:Guhanahana amakuru hagati ya satelite hakoreshejwe uburyo bwa bandwidth bwinshi kugira ngo ibikorwa bihuzwe.

Ubushakashatsi mu kirere cyimbitse:Itumanaho ryihuse kandi rikora intera ndende ku bijyanye n'urugendo rw'ukwezi, Mars, n'izindi ngendo zo mu kirere.
Itumanaho Ritekanye kandi Rifite Umutekano:Kohereza ubutumwa bugufi mu buryo buciriritse birarwanya cyane kumviriza amakuru kandi bishyigikira QKD n'izindi porogaramu zifite umutekano mwinshi.

Ibibazo Bikunze Kubazwa

Q1. Ni izihe nyungu nyamukuru z'itumanaho rya laser kuruta RF isanzwe?
A.Umuyoboro wa interineti uri hejuru cyane (amagana ya Mbps kuri multi-Gbps), ubudahangarwa bwiza bwo guhangana n'ingaruka za elegitoroniki, umutekano w'imiyoboro wa interineti urushaho kwiyongera, kandi ingano/ingufu zigabanuka ku ngengo y'imari ingana n'iyo.

Ikibazo cya 2. Ni izihe misiyo zikwiriye izi terminale?
A.

Amasano hagati ya satelite mu matsinda manini y'inyenyeri
Imiyoboro yo hasi ikoresha satelite nyinshi cyane
Gushakisha mu kirere cyimbitse (urugero, ubutumwa bwo ku kwezi cyangwa ubwo ku mubumbe wa Mars)
Itumanaho ryizewe cyangwa rihishe mu buryo bwa quantum

Q3. Ni ibihe bipimo bisanzwe by'amakuru n'intera bishyigikiwe?

Aho umuhanda unyura mu nzira inyura:kugeza kuri 10 Gbps ku cyerekezo cy'imirongo ibiri hejuru ya ~3,000 km
Terminal ya D60:100 Mbps mu cyerekezo cy'imirongo ibiri hejuru ya ~5,000 km
