Ito ay Plano na Maglunsad ng 12 Satellite sa 2021 upang Makamit ang Zero Breakthrough sa Laser Communication ng Domestic Satellite Constellation ng Internet of Things

Natutunan mula sa China Aerospace Science at grupo ng industriya na ang cloud project Sa kasalukuyan, ang phase construction ay sinimulan na. Ito ay binalak na maglunsad ng 12 satellite sa 2021. Sa oras na iyon, ang pandaigdigang kapasidad ng serbisyo ng space-based na Internet of things ay makabuluhang mapapahusay. Ang Xingyun project ay ang unang low orbit narrow-band Internet of things satellite constellation na independiyenteng namuhunan at binuo ng China Aerospace Science at grupo ng industriya. Aerospace Sanjiang Aerospace Xingyun Technology Co., Ltd. ay responsable para sa konstruksyon at operasyon Sa tatlong yugto, ito ay binalak na bumuo ng isang konstelasyon na binubuo ng 80 LEO na mga satellite ng komunikasyon sa paligid ng 2023. Mabisang malulutas ng cloud engineering ang problema ng communication blind area na dulot ng hindi sapat na coverage ng ground cellular communication network (sa kasalukuyan, ang saklaw ng lupa ay humigit-kumulang 20%, at ang saklaw ng karagatan ay mas mababa sa 5%). Noong nakaraang araw, dalawang- Ang paraan ng komunikasyon na may kumpletong proseso ng pagbuo ng kadena at matatag na katayuan ng telemetry ay natanto sa pagitan ng xingyun-2 satellite 01 at 02, na nangangahulugan na ang teknolohiya ng laser communication payload na dala ng xingyun-2 satellite ay matagumpay na na-verify, at ang Chinese Satellite Internet of things constellation ay mayroong nakamit ang isang pambihirang tagumpay ng zero inter satellite laser communication.

Ang inter satellite laser communication ay isang paraan ng komunikasyon na gumagamit ng laser beam bilang carrier upang magpadala ng imahe, boses, signal at iba pang impormasyon sa kalawakan. Ito ay may mga pakinabang ng mataas na rate ng paghahatid, malakas na kakayahan sa anti-interference, maliit na dami ng terminal ng system, magaan ang timbang at mababang paggamit ng kuryente. Maaari nitong lubos na mabawasan ang pag-asa ng satellite constellation system sa ground network, upang mabawasan ang bilang at gastos ng ground gateway stations, Palawakin ang saklaw na lugar at mapagtanto ang pandaigdigang pagsukat at kontrol. Iniulat na ang laser communication load mass ng xingyun-2 satellite 01 at 02 ay 6.5kg, at ang on orbit power consumption ay 80W.

Sa kasalukuyan, ang inter satellite laser link technology ay naging isang pangunahing teknolohiya sa pagbuo ng global satellite communication system. Ipinapakita ng pampublikong impormasyon na kabilang sa mga proyekto ng konstelasyon na mababa at katamtamang orbit sa buong mundo, tanging ang konstelasyon ng Starlink at konstelasyon ng LEOSAT ng Estados Unidos ang nagmungkahi ng plano ng paggamit ng inter satellite laser link upang maisakatuparan ang space networking. Sa Tsina, binuo ng kumpanya ng Xingyun ang pinakamaliit na inter satellite laser communication load sa China, nakamit ang isang pambihirang tagumpay sa zero laser communication ng domestic satellite Internet of things constellation, at binuksan ang bottleneck ng paghahatid ng impormasyon sa pagitan ng Satellite Internet of things constellations.
