Thanks to CTOnews.com netizen Bai Zhantang for the clue delivery! CTOnews.com, April 25, according to the official website of Dalian University of Technology, at the 2023 China Aerospace Congress-the Seventh small Satellite Technology Exchange Conference, the leader of the OpenHarmony InSpace working Group (Open Atomic Open Source Foundation Project Group Aerospace working Group) led by Dalian University of Technology and Professor Yu Xiaozhou of Dalian University of Technology announced in a keynote report entitled "Micro-Nano Satellite Technology and OpenHarmony Real-time operating system". The OpenHarmony operating system has been successfully applied to high-performance micro / nano satellites such as "electromagnetic Assembly Test double Star" of Micro Satellite Innovation Research Institute of Chinese Academy of Sciences, "Golden Bauhinia" double Star of Hong Kong Aerospace Science and Technology Group, and "Love Space Science" satellite. Compared with the single micro-nano satellite without operating system, the reliability and real-time performance of the system are significantly improved. In addition, the soon-to-be-launched "Lianli" satellite, designed and developed by Dalian University of Technology, also uses the OpenHarmony operating system.

There are still many micro / nano satellites that do not use the RTOS real-time operating system (CTOnews.com Note: Real Time Operating System,). Today, when the software and hardware of the on-board system are becoming more and more complex, the secondary development of OpenHarmony to build a real-time operating system suitable for aerospace will contribute to the universal and modular design of the spaceborne system, shorten the development cycle, and improve the reliability and real-time performance of micro-nano satellites. Ground simulation and on-orbit experiments show that the response speed of micro-nano satellite single machine such as sun sensor, magnetometer and integrated attitude determination system (AMU) developed by OpenHarmony real-time operating system is greatly improved, and the attitude control performance of satellite platform is excellent.

▲ adopts OpenHarmony high precision magnetometer

▲ adopts OpenHarmony high precision sun sensor

▲ uses OpenHarmony's integrated attitude measurement system, Open Atom Open Source Foundation, which is a non-profit organization dedicated to promoting the development of global open source. It was established in Beijing in June 2020 and jointly sponsored by Alibaba, Baidu, Huawei, Chaochao, Tencent, China Merchants Bank and other technology enterprises. The OpenHarmony InSpace working Group was established in 2021 with the support of Open Atomic Open Source Foundation, with sponsors such as Institute of Software of Chinese Academy of Sciences, Institute of Micro Satellite Innovation of Chinese Academy of Sciences, Tsinghua University, Dalian University of Technology, Wuhan University, Changguang Satellite, Beijing Love Space Science and Technology, Aerospace founder and Middle School attached to Tsinghua University.

In order to promote the application of OpenHarmony in micro / nano satellites and other aerospace fields, the official website of OpenHarmony Inspace has been officially launched, and developers can get the latest version of "OpenHarmony lightweight system Migration Manual" for free and keep abreast of the latest research and engineering progress in this field.
