By reconfiguring satellite software in orbit, researchers on the Pamir Plateau have doubled the capacity of existing laser communications, setting a new domestic speed record.<\/p>\n

The Aerospace Information Research Institute (AIR) under the Chinese Academy of Sciences has successfully completed an operational application experiment that pushes satellite-to-ground laser communication past the 100-gigabit-per-second (Gbps) threshold. Achieving a peak transmission speed of 120 Gbps, this milestone marks a significant improvement in high-speed space data transmission capabilities. <\/p>\n

This achievement builds upon a rapid succession of technological leaps by the AIR team, which previously recorded speeds of 10 Gbps in 2023 and 60 Gbps in 2025. The recent experiment utilized a self-developed 500-millimeter aperture laser ground station situated on the Pamir Plateau in the Xinjiang Uygur Autonomous Region of China, communicating directly with the AIRSAT-02 satellite. <\/p>\n

The engineering team made this breakthrough without any physical hardware modifications to the AIRSAT-02 satellite. The capacity was effectively doubled from 60 Gbps to 120 Gbps purely through in-orbit software reconfiguration, fully unlocking the potential of the existing laser communication payload. <\/p>\n

The test data attest to the stability and efficiency of the new system: <\/p>\n

Rapid link acquisition. The satellite and ground station established connections in seconds, maintaining a success rate exceeding 93%.Continuous transmission. The system sustained a maximum continuous communication duration of 108 seconds.Massive data volume. A total of 12.656 terabits of data were transmitted during the window.<\/p>\n

Li Yalin, senior engineer at AIR and the team’s technical lead, noted the exponential difficulty of this advancement. Li compared the previous 10 Gbps benchmark to a simple single-lane bridge, while describing the 120 Gbps achievement as a complex multi-lane highway requiring both rapid construction and high-efficiency parallel traffic.<\/p>\n

I have always been fascinated by technology and digital devices my entire life and even got addicted to it. I have always marveled at the intricacy of even the simplest digital devices and systems around us. I have been writing and publishing articles online for about 6 years now, just about a year ago, I found myself lost in the marvel of smartphones and laptops we have in our hands every day. I developed a passion for learning about new devices and technologies that come with them and at some point, I asked myself, “Why not get into writing tech articles?” It is useless to say I followed up the idea \u2014 it is evident. I am an open-minded individual who derives an infinite amount of joy from researching and discovering new information, I believe there is so much to learn and such a short life to live, so I put my time to good use \u2014 learning new things. I am a ‘bookworm’ of the internet and digital devices. When I am not writing, you will find me on my devices still, I do explore and admire the beauty of nature and creatures. I am a fast learner and quickly adapt to changes, always looking forward to new adventures.<\/p>\n","protected":false},"excerpt":{"rendered":"\u24d8 Jack B via Unsplash A skyline featuring a light beam By reconfiguring satellite software in orbit, researchers…\n","protected":false},"author":2,"featured_media":482818,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[244714,30897,64,63,234,71398,5225,235,227,233,226,236,232,228,229,128,285,244713,231,230],"class_list":{"0":"post-482817","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-aerospace-information-research-institute","9":"tag-air","10":"tag-au","11":"tag-australia","12":"tag-benchmarks","13":"tag-cas","14":"tag-chinese-academy-of-sciences","15":"tag-graphics-card","16":"tag-laptop","17":"tag-netbook","18":"tag-notebook","19":"tag-processor","20":"tag-reports","21":"tag-review","22":"tag-reviews","23":"tag-science","24":"tag-space","25":"tag-space-ground-data-transfer","26":"tag-test","27":"tag-tests"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/482817","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=482817"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/482817\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/482818"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=482817"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=482817"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=482817"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
