On the morning of July 16th, the China Lauding Rockets Technology Research Institute, which was affiliated to the China Lauding Rocket Technology Research Institute of China Aerospace Technology Group Co., Ltd., took off at the Taiyuan Satellite Launch Center. The two high -resolution commercial remote sensing satellites were sent to the predetermined orbit. The launch task is successful.

These two satellites are mainly field surveys, geographical surveying and mapping, natural disasters monitoring, urban planning and other fields, as well as real -life three -dimensional, urban security, digital basin, financial agriculture and other emerging markets providing commercial remote sensing services.

According to Xie Zhifeng, the overall designer of the Rockets Cross Circle of Rockets No. 2, the mission was first applied to the universal, series, and standardized uniform ground hair test control equipment in the Rocket Academy. The Rocket Institute carried out the unified work of the ground hair measurement control equipment in 2020. After the unified type, the number of Long March No. 2 Cross -load rockets on the ground measuring control equipment was reduced by about 50%, and the ground test with the Long March III Launar Rockets was achieved. Common hair control equipment, simplifying the maintenance work, reducing the difficulty of guarantee, promoting the development of the carrier rocket hair measurement control equipment, improving the active liquid carrier -carrier rocket testing capacity, and also laid a good job to further improve the efficiency of rocket launch efficiency Base.

It is worth noting that in this task, the Long March 2 Cross Rockets also provides a customized "special car" service based on customer needs. The short -term multi -star separation technology, compared to the traditional adjustment of posture separation, has maximum loading capacity, maximizing satellite available measurement and control time, and has good far -field security, reducing the support of the dedicated posture system, simplifying the launch of launching, simplified launching launch Field test process and reduce the advantages of launch costs.

This year, the Long March 2 Crown Rockets are in the stage of multiple new tasks in parallel design, multiple launch fields to advance in parallel, and multiple product lines in parallel production. There are still several tasks in the second half of the year. The Rockets development team uses the digital shooting range management system and in -depth integration of the post to ensure the quality and ensure the launch on time.

The 01 and 02 stars launched this time are two high -resolution commercial remote sensing satellites of China Aerospace Technology Group China Four -dimensional Testing and Drawing Technology Co., Ltd. Development, Beijing Aerospace Yuxing Technology Co., Ltd. provides two satellite measurement and control services exclusively as the overall unit of measurement and control.

Liang Tao, deputy minister of the overall department of the Aerospace Yingxing System, introduced that based on the task experience of the 01 and 02 stars of Siwei Gaojing No. 1, Aerospace Yuxing will take the test software system from task planning, automatic surveillance alarm on track failure, remote control operation process, number, number of numbers, numbers, and numbers The receiving processing process has been upgraded and optimized.

The Aerospace Yuxing Flying Control Center is precisely deployed with the three places of the China Four -dimensional and Aerospace Council's Transportation Management Center. During the launching stage and the engineering testing phase, the trilogy pilot team worked in the Aerospace Control Center, and was responsible for satellite remote control remote control, rail control, data receiving and emergency disposal. China Siwei undertake satellites in rail surveillance and business planning, and the Fifth Academy's Transportation Management Center undertakes satellite surveillance in rail status.

China Siwei successfully launched the Four -dimensional Gaojing No. 1 01 and 02 star on April 29, 2022. The two satellites launched this time are the second group of satellites of China's four -dimensional new generation of commercial remote sensing satellite system. After the satellite is put into use, it will significantly improve the data acquisition and information service capabilities of China's four -dimensional commercial remote sensing satellite system, marking the complete success of the construction of the system in the first stage of the system.

In May 2020, China's four -dimensional launching a new generation of commercial remote sensing satellite system was launched. The space section planned to launch 28 satellites, which was constructed simultaneously to match the ground section based on the "Four Wei Clouds". , Follow -up can be extended to 56 satellites according to market development.

It is reported that the four -dimensional commercial remote sensing satellite system in China will be fully completed in 2025. At that time, the system will have 25 high -scale visits capabilities in the world, a daily collection area of ​​more than 30 million square kilometers of high collection capabilities, and emergency delivery capabilities within 2 hours.
