China<\/a> has successfully tested a home-grown operating system in space<\/a>, marking a major step towards reducing reliance on foreign software and boosting the performance of future small satellites.More than 1,000 hours of in-orbit testing were conducted aboard the Dalian-1 Lianli CubeSat to evaluate how satellite subsystems performed under the OpenHarmony real-time operating system (RTOS) \u2013 a lightweight version of Huawei<\/a>\u2019s open-source operation platform, according to a team of researchers from the Chinese cities of Dalian and Xian.With OpenHarmony<\/a>, the suitcase-sized satellite, which was released from China\u2019s Tiangong space station last year, delivered faster data updates and improved stability compared with earlier set-ups using simpler firmware or foreign software, the researchers reported in the latest issue of the journal Space: Science and Technology.<\/p>\n

\u201cThe Lianli satellite mission showed that using the OpenHarmony real-time operating system significantly improved the satellite\u2019s response speed and reliability,\u201d Yu Xiaozhou, the paper\u2019s lead author and a professor at Dalian University of Technology, told Chinese media in May.<\/p>\n

As the first microsatellite to carry the OpenHarmony RTOS, Lianli also ran on a domestically produced chip, \u201cachieving a fully home-grown hardware-software solution in the field, and offering a new option for spacecraft operating systems worldwide\u201d, according to Chinese media reports.<\/p>\n

Following the Lianli mission, Yu and colleagues proposed national technical standards to guide how OpenHarmony is used in small satellites \u2013 a step intended to encourage broader adoption, which is already taking place across both commercial and research satellite missions in China.<\/p>\n","protected":false},"excerpt":{"rendered":"China has successfully tested a home-grown operating system in space, marking a major step towards reducing reliance on…\n","protected":false},"author":3,"featured_media":2689,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[24],"tags":[3623,74,3619,3625,3627,3617,917,3618,2012,3620,3624,3621,3626,159,783,3622,67,132,68],"class_list":{"0":"post-2688","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-american-technologies","9":"tag-china","10":"tag-chinese-satellite","11":"tag-cubesat","12":"tag-dalian","13":"tag-dalian-university-of-technology","14":"tag-earth","15":"tag-google-services","16":"tag-huawei","17":"tag-lianli","18":"tag-openatom-foundation","19":"tag-openharmony","20":"tag-openharmony-rtos","21":"tag-science","22":"tag-space","23":"tag-tiangong-space-station","24":"tag-united-states","25":"tag-unitedstates","26":"tag-us"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/114722058632091818","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/2688","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=2688"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/2688\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/2689"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=2688"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=2688"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=2688"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
