Achieving a peak transmission speed of 120 Gbps, this milestone marks a significant improvement in high-speed space data transmission capabilities. &#13;<\/p>\n<p class=\"bodytext\">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. &#13;<\/p>\n<p class=\"bodytext\">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. &#13;<\/p>\n<p class=\"bodytext\">The test data attest to the stability and efficiency of the new system: <\/p>\n<ul>\n<li><strong>Rapid link acquisition<\/strong>. The satellite and ground station established connections in seconds, maintaining a success rate exceeding 93%.<\/li>\n<li><strong>Continuous transmission<\/strong>. The system sustained a maximum continuous communication duration of 108 seconds.<\/li>\n<li><strong>Massive data volume<\/strong>. A total of 12.656 terabits of data were transmitted during the window.<\/li>\n<\/ul>\n<p class=\"bodytext\">Li Yalin, senior engineer at AIR and the team&#8217;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<p>\tThe laser ground station used to carry out the experiment<\/p>\n<p>\t<a href=\"https:\/\/www.notebookcheck.net\/Notebookcheck-Team.212978.0.html?&amp;tx_nbc2journalist_pi1%5Bmode%5D=show&amp;tx_nbc2journalist_pi1%5Buid%5D=369\" rel=\"nofollow noopener\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/www.europesays.com\/ie\/wp-content\/uploads\/2025\/08\/csm_Chibuike_Okpara_82951fce8f.jpg\" loading=\"lazy\" width=\"120\" height=\"120\" alt=\"Chibuike Okpara\"\/><\/a><a href=\"https:\/\/www.notebookcheck.net\/Notebookcheck-Team.212978.0.html?&amp;tx_nbc2journalist_pi1%5Bmode%5D=show&amp;tx_nbc2journalist_pi1%5Buid%5D=369\" class=\"j_name\" rel=\"nofollow noopener\" target=\"_blank\">Chibuike Okpara<\/a> &#8211; Tech Writer  &#8211; 400 articles published on Notebookcheck since 2024<\/p>\n<p>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, &#8220;Why not get into writing tech articles?&#8221; 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 &#8216;bookworm&#8217; 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&hellip;\n","protected":false},"author":2,"featured_media":339091,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[77],"tags":[160954,25107,1820,20370,4563,18,1821,19,17,1815,1819,1814,1822,1818,1142,1143,133,160953,1817,1816],"class_list":["post-339090","post","type-post","status-publish","format-standard","has-post-thumbnail","category-science","tag-aerospace-information-research-institute","tag-air","tag-benchmarks","tag-cas","tag-chinese-academy-of-sciences","tag-eire","tag-graphics-card","tag-ie","tag-ireland","tag-laptop","tag-netbook","tag-notebook","tag-processor","tag-reports","tag-review","tag-reviews","tag-science","tag-space-ground-data-transfer","tag-test","tag-tests"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ie\/116076306264356776","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/339090","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=339090"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/339090\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/339091"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=339090"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=339090"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=339090"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
