Izingxenye Zokuxhumana Nge-Laser Yesivinini Esikhulu Nezithombe Ezifakiwe Zezikhumulo

Incazelo emfushane:

Yakhelwe ukuxhumana kwesathelayithi yesizukulwane esilandelayo, lo mndeni wezingxenye zokuxhumana nge-laser namatheminali usebenzisa ukuhlanganiswa okuthuthukisiwe kwe-opto mechanical kanye nobuchwepheshe be-laser obuseduze ne-infrared ukuletha izixhumanisi ezinesivinini esikhulu, ezinokwethenjelwa kukho kokubili ukuxhumana kwe-inter-satellite kanye ne-satellite-to-ground.

Uhlolojikelele

Uma kuqhathaniswa nezinhlelo ze-RF zendabuko, ukuxhumana nge-laser kunikeza umkhawulokudonsa ophakeme ngokuphawulekayo, ukusetshenziswa kwamandla okuphansi, kanye nokuvimbela ukuphazamiseka nokuphepha okuphakeme. Ifaneleka kahle kuma-constellations amakhulu, ukubukwa komhlaba, ukuhlola indawo ejulile, kanye nokuxhumana okuvikelekile/umthamo.

Iphothifoliyo ihlanganisa ukunemba okuphezulu kwe-optical assemblies, amatheminali e-inter-satellite kanye nesathelayithi-to-ground laser, kanye nohlelo olubanzi lokuhlola olulingana nenkundla ekude—olwakha isisombululo esiphelele sokuphela-kuya-ekupheleni.
