Laser Communication Payload

Laser Communication Payload e kenyelletsa litefiso tsa eona tse phahameng tsa phetisetso ea data, e fanang ka puisano e potlakileng le e sebetsang haholoanyane ha e bapisoa le lits'ebetso tse tloaelehileng tsa RF, e etsa hore e be se loketseng bakeng sa lits'ebetso tse matla haholo tsa data joalo ka litšoantšo tse phahameng tsa satellite le puisano e tebileng ea sebaka. Likarolo tsa eona tsa ts'ireletso li e etsa hore e se ke ea kena-kenana le ho kena-kenana le mathata, ho netefatsa hore data ea bohlokoa e lula e sirelelitsoe. Moralo o kopaneng oa sistimi o lumella ho hokahana ha bonolo ho litsamaiso tse teng tsa sepaka-paka le sathelaete, ha tšebeliso ea eona e tlase ea matla e ntlafatsa katleho ea thōmo. Ho phaella moo, bokhoni ba eona ba ho fana ka puisano e phahameng ea li-bandwidth ho feta libaka tse telele ho etsa hore e fetole papali bakeng sa ho hlahloba sebaka sa nakong e tlang le marang-rang a puisano a lefats'e.

Laser Communication Payload ke sistimi e tsoetseng pele e etselitsoeng ho fana ka phetiso ea data ea lebelo le holimo, e bolokehileng, le ea nako e telele e sebelisa maballo a laser. Phaello ena e na le li-transmitters tsa laser, li-receiver, le li-module tsa puisano tsa optical, tse sebetsang 'moho ho theha sehokelo se tsitsitseng le se phahameng bakeng sa puisano ea satellite, tlhahlobo ea sebaka, le lits'ebetso tse thehiloeng fatše. Sistimi ena e sebelisa theknoloji ea laser ea infrared ho fetisa data ka lebelo le holimo haholo ha e bapisoa le litsamaiso tsa puisano tsa radio frequency (RF), e nolofalletsang phetiso ea lipalo tse kholo tsa data ntle le tieho e fokolang. Phatlalatso ea puisano ea laser e etselitsoe ho sebetsana le phetisetso e sireletsehileng haholo, ho netefatsa bots'epehi ba data le ho hana ho kheloha. E na le litsamaiso tse phahameng tse nepahetseng tsa ho supa le ho latela, ho netefatsa hore lebone la laser le lula le tsamaisitsoe ka nepo lipakeng tsa li-unit tse fetisang le tse amohelang, esita le libakeng tse matla joalo ka motsamao oa sathelaete. E etselitsoe mosebetsi oa sepakapaka, e khona ho sebetsa maemong a mocheso a feteletseng le ho mamella maemo a thata a sebaka, e fana ka puisano e tšepahalang libakeng tse telele.
