One arrow double star!Long Erbing Rockets successfully launched four -dimensional 03/04 satellite

China News Agency, Beijing, July 16th (Mazahasha) At 6:57 on July 16, Beijing time, China used the Long March 2 to carry the Rockets in the Taiyuan Satellite Launch Center and successfully launched the four -dimensional 03/04 satellite (also known as::: Siwei Gaojing No. 2 01, 02 stars).

The two satellites launched this time are two high -resolution business remote sensing satellites of China Four -dimensional Testing and Drawing Technology Co., Ltd. (referred to as China Four -dimensional), which belong to China Aerospace Technology Group, and developed by the Fifth Hospital of Aerospace Technology Group. Satellites mainly serve emerging markets such as urban security, real -life three -dimensional, urban information models, digital agriculture, as well as traditional fields such as land surveying, disaster prevention and mitigation, maritime monitoring, etc., to provide users with high time and high -performance space -time information services.

Siwei Gaojing No. 1 01 and 02 stars successfully launched on April 29, 2022. Four -dimensional 03/04 satellite is 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 the system, marking the successful success of the system in the system.

In May 2020, China's four -dimensional launch of a new generation of commercial remote sensing satellite system demonstration. The space section plan launched a total of 28 satellites of "16+4+8". Simultaneous construction matching the ground segment (including test control, receiving, processing, processing, processing, treatment, , Application), followed by market development to 56 satellites.

It is reported that the system will be fully completed in 2025. At that time, it will have a high -heavy visits capacity of 25 times a day, a daily collection area of ​​more than 30 million square kilometers, and emergency delivery capabilities within 2 hours.

Long March No. 2 Cross Rockets is a normal temperature liquid carrier rocket developed by the First Hospital of Aerospace Technology Group. In this task, the Rockets use a two -level state structure, the total length of the whole arrow is about 45 meters, and the take -off mass is about 242 tons. In this task, the Long March 2 Cross Rockets provided a customized "special car" service, which adopts a lengthened version of the 3.35 -meter diameter rectifier to make the satellite "riding" more comfortable.

In addition, the Rockets adopt high -efficiency and simple short -time multi -star separation technology. Compared with the traditional adjustment of posture, it has maximum load capacity, maximizing the available satellite available measurement time, and has good far -field security, reducing the dedicated posture of special adjustment positions System support, simplify the processing process of the launch field, and reduce the cost of launch costs.

This launch is the 427th launch of the Long March series of launch vehicles.
