China's First Software-Definition Satellite "Tianzhi No. 1" to Launch in the Second Half of the Year
China News Service, Beijing, April 7 (Reporter Sun Zifa) Zhao Junsuo, researcher of the Institute of Software of the Chinese Academy of Sciences and secretary-general of the Software-Defined Satellite Technology Alliance, revealed on the 7th that China’s first software-defined satellite “Tianzhi No. 1” is currently progressing smoothly. It is expected that launch launches will be launched at the Jiuquan Satellite Launch Center in the second half of this year.
The "2018 Software Defined Satellite Summit" with the theme of "Software Defined Satellites, Smart Leading Aerospace" was opened in Beijing on the same day. When Zhao Junsuo accepted an interview with a reporter from the China News Service, he said that the "Channel 1" software led by the Chinese Academy of Sciences Software. The definition of the satellite project began in August 2015. It was officially initiated by the major science and technology task bureau of the Chinese Academy of Sciences in 2017. The Institute of Microsatellite Innovation of the Chinese Academy of Sciences undertook satellite development and testing. After launching the satellite in the second half of this year, it will conduct on-orbit test verification.
The Tianzhi I, named after the space-based intelligence, is a software-based satellite. The main payload is a small-scale cloud computing platform with low energy consumption and strong computational capabilities to execute over-the-air applications. Its payload also includes the passing of Reinforced 4 domestic smart phones. Different from the traditional satellites' custom development and self-contained closed system for single tasks, Tianzhi No. 1 focuses on providing platform solutions that integrate general software, developing aerospace software suitable for different satellite platforms, and launching the “space application store”. Rich space ecology applications allow users more choices.
Zhao Junsuo pointed out that compared to this, the "Tianzhi No.1" satellite has three major advantages. First, it has a high degree of intelligence. Most of the data processing that satellites receive can be completed in orbit, and the ground is transferred as needed; the second is the satellite's openness. Type system, everyone can develop software for satellites, and can develop satellite software according to a certain process to bid on satellites and carry out on-orbit trials; third is the real-time status of satellites. Everyone can use the "chasing star APP" to access queries through mobile phones. , And command satellites to perform real-time space missions such as "self-timer in space."
He also revealed that the Institute of Software of the Chinese Academy of Sciences and the Software Defined Satellite Technology Alliance have now begun to plan the research and development of the satellite "Tianzhi II" and "Tianzhi III", and has started the demonstration of the "Tianzhi II" satellite. “Our goal is not to research and develop how many satellites are launched. Instead, we must build an integrated solution based on software definition and providing satellite-based general software, just like the mobile phone's Android system, and eventually build a widely used space-based intelligent system, sputnix.”
