According to Xinhua News Agency, on the 18th, at 11:56:24 on August 17, the Mizon Station, a remote sensing satellite ground station of the Chinese Academy of Sciences Institute of Remote Sensing and Digital Earth, successfully tracked and received quantum satellite ink on the 23rd lap. The first track data of the child number is sent to the National Space Science Center of the Chinese Academy of Sciences in real time. The length of the first track of Mozi is about 7 minutes, and the total amount of data received is about 202MB. After verification, the satellite data quality is good.
As the world’s first quantum scientific experimental satellite independently developed by China, Mozi successfully launched its launch at Jiuquan, Gansu, at 1:40 am on August 16.
The main scientific goal of Mozi is to use the satellite platform to conduct quantum key distribution experiments at Xingdi High-speed, and based on this, a wide-area quantum key network experiment is conducted, with a view to achieving a major breakthrough in the practical application of space quantum communication.
Mozi is one of the first scientific experimental satellites of space science pilots of the Chinese Academy of Sciences, and is the third satellite of China’s space science satellite series following the dark matter particle detection satellite and the practice of the No. 10 satellite.
The China Remote Sensing Satellite Ground Station is responsible for the construction and operation of the space science pioneering special ground receiving system of the Chinese Academy of Sciences. At present, it has built a network of near-Earth space science satellite receiving stations geographically located in the South, North and West of China.
The task of observation and data reception for Mozi was coordinated by the Miyun Station, Kashi Station, and Sanya Station of the China Remote Sensing Satellite Ground Station. In the future, China’s remote-sensing satellite ground station will continue to undertake data receiving tasks for many subsequent space science satellites, including Chinese hard X-ray modulation telescope satellites.
It is understood that with the success of the first quantum satellite experiment, China will successively launch subsequent satellites, and combine future space station projects to carry out relevant research to verify the feasibility of inter-satellite and all-day quantum communications. Pan Jianwei, chief scientist of China’s quantum satellite and academician of the Chinese Academy of Sciences, said: “According to the plan, by 2020, China will realize the intercontinental quantum key distribution in Asia and Europe; by 2030, China will build a global wide-area quantum communication network.†The successful reception of this data undoubtedly marks that China’s space science and technology have taken a big step towards this goal.
