html At 6:57 on July 16, the Long March 2C carrier rocket (hereinafter referred to as the Long March 2C rocket) ignited and took off at the Taiyuan Satellite Launch Center , carrying the 4D High-precision 201, The 02 satellite (also known as the four-dimensional 03/04 satellite) was sent into the predetermined orbit in the form of two satellites in one stone, and the launch mission was a complete success.

The Long March 2C launch vehicle was developed by the First Research Institute of China Aerospace Science and Technology Corporation. According to Xie Zhifeng, chief designer of the first-generation Dean and second-generation propylene rockets, this mission is the first time that universal, serialized, and standardized unified ground measurement and control equipment has been applied in the launch mission of the First Academy of Aerospace.

It is understood that the First Research Institute carried out the unified finalization of ground testing, launch and control equipment in 2020. After the unified model, the number of Chang'e C rocket ground test, launch and control equipment will be reduced by about 50%, and it will be common with the Changan 3a series rocket ground test, launch and control equipment, simplifying use and maintenance work, reducing the difficulty of support, and promoting the launch vehicle The equipment development of test, launch and control equipment has improved the test and launch capabilities of conventional liquid launch vehicles in service, laying a good foundation for further improving rocket launch efficiency.

In this mission, the Chang'e-C rocket provided customized "special carrier" services according to launch needs, and used an extended fairing with a diameter of 3.35 meters to make the satellite "ride" more comfortable; an efficient and simple short-duration multiple Star separation technology. Compared with the traditional attitude adjustment separation scheme, it has the advantages of maximizing the satellite carrying capacity and available measurement and control time, has better far-field security, reduces the support of special attitude adjustment systems, and simplifies the measurement of at the launch site and development process, reducing launch costs.

In 2022, the Chang'e-C rocket is in the ultra-high-density launch stage of parallel design of multiple new missions, parallel propulsion of multiple launch sites, and parallel production of multiple product lines. There are several tasks for the second half of this year.

It is reported that the satellites launched this time mainly serve emerging markets such as urban security, real 3D, urban information models, and digital agriculture, as well as traditional fields such as land surveying and mapping, disaster prevention and reduction, and ocean monitoring, providing users with high-time, high-performance Space-time information service.
