At 2:57 on November 1, the Long March 3B carrier rocket was ignited at the Xichang Satellite Launch Center, and the first geosynchronous orbit satellite of the Beidou No. 3 project was successfully put into the orbit. This is the 41th Beidou navigation satellite launched by the Changjiajia series of rockets.

By the end of the year, the basic system will be built to serve the countries along the “Belt and Road”

The launch is the eleventh launch of the Changanjia series of rockets this year. After the first annual launch of the Changanjia series of rockets reached 10 on October 15, the annual number of launches was again updated. This mission is the 93rd launch of the Changjiao series of rockets and the 290th launch of the Long March series of launch vehicles.

Yang Changfeng, chief designer of Beidou satellite navigation system, introduced that the satellite launched this time is the first geostationary orbit satellite of Beidou No.3 system and the seventeenth satellite network of China Beidou No.3 system. In addition to providing basic navigation services, the satellite will also provide short message service. Based on the full compatibility with the Beidou II short message service, the satellite will increase capacity by 10 times and reduce the transmission power of the user machine by 10 times.

The satellite will also provide satellite-based enhancement services that will provide higher-precision, higher-precision navigation services in accordance with international civil aviation standards. After the successful launch of the satellite, it will be tested and tested, and will be networked with the 16 Beidou-3 navigation satellites previously launched to provide timely services. According to the plan, two medium-Earth orbit satellites will be launched before the end of the year to build a basic system to serve the countries along the Belt and Road Initiative. It is planned to build a world-class Beidou No. 3 system by the end of 2020 to provide global services.

From research to launch, Shaanxi figure adds strength to the space industry

Shaanxi is a place where Chinese scientific research institutes are concentrated. This launch is naturally indispensable to Shaanxi. The aerospace powerhouse, the power first, the Western Network reporter learned that the power of this launch rocket engine comes from the Sixth Research Institute of Aerospace Science and Technology Group in Xi'an. The Xi'an Branch of the Aerospace Five Institute provided all the payload products for the Beidou satellite, such as the navigation subsystem, the antenna subsystem, the transponder subsystem, and the inter-satellite link.

In addition to aerospace research and production units, many space workers at the Xichang Satellite Launch Center are also from Shaanxi. Zhang Runhong, the first female launcher of the female launch position, came from Hancheng, Shaanxi; the conventional combustion agent test operator Hao Zhaowen was the post-90s of Shaanxi Jude. The oxygen-nitrogen filling site commander and the liquid nitrogen main control microcomputer operator Li Minkai were from Shaanxi. County people... Incomplete statistics, Xichang Satellite Launch Center is typical of nearly 10 people in Shaanxi.

In addition, as the "hometown of aerospace power", the United Nations International Committee for Global Navigation Satellite Systems will hold the thirteenth conference in Xi'an, the ancient capital of the "Silk Road" starting point on November 5, and related to countries around the world. Organize experts to communicate and strengthen cooperation to jointly promote the global navigation system to flourish.

Beidou has formed a complete industrial chain. Huize Shaanxi several projects

As one of the earliest provinces engaged in the research and development of satellite navigation applications, Shaanxi Province has more than 100 enterprises and institutions engaged in the research and development, manufacturing, system integration and operation services of Beidou satellite navigation applications, which has formed a relatively complete industrial chain. According to Yang Changfeng, in terms of application and industrialization, China has formed a complete industrial chain of Beidou. Beidou is standardized in national security and key areas, and is applied in large-scale applications in the mass consumption field. It is stimulating a new model of “Beidou+” integration application.

Since the trial operation of the Beidou satellite navigation and positioning base station system in Shaanxi Province, the number of registered users has exceeded 30 units. In December 2016, the Beidou satellite navigation and positioning base station project in Shaanxi Province was fully launched. After more than one year, a total of 88 base stations were built, of which 60 were newly built and 28 were upgraded. Since the system was commissioned, the user approval has passed through 30 provincial units, providing and publishing system user accounts up to 120.

Shaanxi Beidou Satellite Application Demonstration Project focuses on the field of people's livelihood engineering and ecological protection, focusing on the construction of Beidou's industrial technology innovation service platform and comprehensive operation service platform for 120 ambulances near the rescue, Hanzhong Meteorological Bureau meteorological disaster monitoring, and Weinan's drone precision.
