Lesa Communication Payload

Isanwo Ibaraẹnisọrọ Laser pẹlu awọn oṣuwọn gbigbe data giga rẹ, fifun ni iyara ati ibaraẹnisọrọ daradara diẹ sii ni akawe si awọn eto RF ti aṣa, ti o jẹ ki o jẹ apẹrẹ fun awọn ohun elo aladanla data gẹgẹbi aworan satẹlaiti giga-giga ati ibaraẹnisọrọ aaye jinna. Awọn ẹya aabo rẹ jẹ ki o tako idawọle tabi jamming, ni idaniloju pe data ifura wa ni aabo. Apẹrẹ iwapọ ti eto naa ngbanilaaye fun isọpọ irọrun sinu awọn ọkọ ofurufu ti o wa tẹlẹ ati awọn ọna ṣiṣe satẹlaiti, lakoko ti agbara kekere rẹ ṣe imudara iṣẹ apinfunni. Ni afikun, agbara rẹ lati pese ibaraẹnisọrọ bandiwidi giga lori awọn ijinna pipẹ jẹ ki o jẹ oluyipada ere fun iṣawari aaye iwaju ati awọn nẹtiwọọki ibaraẹnisọrọ agbaye.

Isanwo Ibaraẹnisọrọ Laser jẹ eto fafa ti a ṣe apẹrẹ lati pese iyara giga, aabo, ati gbigbe data gigun ni lilo awọn ina ina lesa. Isanwo isanwo yii ni awọn atagba laser, awọn olugba, ati awọn modulu ibaraẹnisọrọ opiti, eyiti o ṣiṣẹ papọ lati fi idi ọna asopọ iduroṣinṣin ati agbara giga fun ibaraẹnisọrọ satẹlaiti, iṣawari aaye, ati awọn ohun elo ti o da lori ilẹ. Eto naa nmu imọ-ẹrọ infurarẹẹdi infurarẹẹdi lati tan kaakiri data ni awọn iyara ti o ga julọ ni akawe si awọn eto ibaraẹnisọrọ igbohunsafẹfẹ redio ibile (RF), ti o mu ki gbigbe awọn iwọn data nla pọ si pẹlu idaduro kekere. Isanwo ibaraẹnisọrọ lesa ti jẹ ẹrọ lati mu gbigbe to ni aabo to gaju, ni idaniloju iduroṣinṣin data ati atako si interception. O ṣe ẹya itọka pipe-giga ati awọn ọna ṣiṣe titele, ni idaniloju pe ina ina lesa wa ni itọsọna ni deede laarin gbigbe ati awọn ẹya gbigba, paapaa ni awọn agbegbe ti o ni agbara bi gbigbe satẹlaiti. Ti a ṣe apẹrẹ fun awọn iṣẹ apinfunni aaye, o le ṣiṣẹ ni awọn iwọn otutu to gaju ati ki o koju awọn ipo lile ti aaye, pese ibaraẹnisọrọ ti o gbẹkẹle kọja awọn ijinna pipẹ.
