Laser Communication Payload

Laser Communication Payload imaphatikizanso kuchuluka kwa ma data, omwe amapereka kulumikizana mwachangu komanso kothandiza kwambiri poyerekeza ndi machitidwe wamba a RF, ndikupangitsa kuti ikhale yabwino pazogwiritsa ntchito zambiri za data monga kujambula kwa satellite yapamwamba komanso kulumikizana kwakuya kwamlengalenga. Mawonekedwe ake achitetezo amapangitsa kuti isavutike kulandidwa kapena kutsekereza, kuwonetsetsa kuti deta yodziwika bwino imakhala yotetezedwa. Mapangidwe ophatikizika a makinawa amalola kuphatikizika kosavuta ndi makina omwe alipo kale komanso ma satelayiti, pomwe kugwiritsa ntchito mphamvu zake zochepa kumapangitsa kuti ntchito zitheke. Kuphatikiza apo, kuthekera kwake kopereka kulumikizana kwapamwamba kwa bandwidth pamtunda wautali kumapangitsa kusintha kwamasewera pakufufuza kwamtsogolo komanso maukonde olumikizana padziko lonse lapansi.

Laser Communication Payload ndi njira yotsogola yopangidwa kuti ipereke kutumiza kwa data mwachangu, kotetezeka, komanso kwautali wogwiritsa ntchito matabwa a laser. Malipirowa amakhala ndi ma transmitters a laser, olandila, ndi ma module olumikizirana owoneka bwino, omwe amagwirira ntchito limodzi kuti akhazikitse ulalo wokhazikika komanso wapamwamba kwambiri wolumikizirana ndi satellite, kufufuza malo, ndi kugwiritsa ntchito pansi. Dongosololi limathandizira ukadaulo wa laser wa infrared kuti utumize deta pa liwiro lokwera kwambiri poyerekeza ndi njira zoyankhulirana zama radio frequency (RF), zomwe zimathandizira kusamutsa ma voliyumu akulu ndikuchedwa pang'ono. Malipiro olumikizirana a laser amapangidwa kuti azigwira ntchito zotetezedwa kwambiri, kuwonetsetsa kukhulupirika kwa data komanso kukana kulandidwa. Imakhala ndi njira zolozera bwino kwambiri komanso zotsatirira, kuwonetsetsa kuti mtengo wa laser umakhalabe wolunjika bwino pakati pa mayunitsi otumizira ndi kulandira, ngakhale m'malo osunthika ngati kuyenda kwa satellite. Zopangidwira maulendo amlengalenga, zimatha kugwira ntchito kutentha kwambiri komanso kupirira mikhalidwe yovuta ya mlengalenga, kupereka kulankhulana kodalirika pamtunda wautali.
