China Beidou system began to provide global services today!

At the press conference held on the afternoon of December 27th, the director of the China Satellite Navigation System Management Office and the Beidou satellite navigation system spokesperson Yu Chengqi announced:

The construction of the basic system of the Beidou No. 3 was completed and began to provide global services today. It marks that the service scope of the Beidou system has expanded from the region to the world, and the Beidou system has officially entered the global era.

2018 is the most arduous year for the construction of the Beidou system.

According to reports, the Beidou system is a global satellite navigation system that is independently constructed and operated independently by China and is compatible with other satellite navigation systems in the world. It can provide high-precision and high-reliability positioning for all kinds of users on a global scale, all-weather and all-day. , navigation, timing service.

Since the 1990s, the Beidou system has been developed and developed according to the "three-step" development strategy. It is first active and passive, first regional and global, and has built Beidou-1, Beidou-2 and Beidou No.3 systems. A road for the construction of satellite navigation systems with Chinese characteristics.

Today, in 2012, Beidou Systems provides services to the Asia-Pacific region; six years later, the Beidou system is open to the world. The construction of the Beidou system has broken through more than 100 key technologies in four major categories, ensuring stable and moderate service in the Asia-Pacific region, completing the construction of the global service core constellation network, and realizing the overall jump in China's space capability.

2018 is an extraordinary year in the history of the development of the Beidou system, and it is also the most arduous year of construction. Network transmission creates records, system operation ensures stability, international cooperation highlights are numerous, and application promotion has achieved remarkable results:

First, the high-density density network formed a global service capability, and completed 10 arrows and 19 stars in one year, setting a new record for the construction of the world's satellite navigation system and the same type of space launch in China.

Second, the high-reliability operation maintains stable services in the Asia-Pacific region, develops and launches backup satellites, continuously refines the orbit control strategy, and operates the ground system with high stability, strengthens global monitoring and evaluation, ensures a smooth transition of the system, and achieves stable and improved service performance.

Third, high standards to create new highlights of international cooperation, successfully hosted the 13th International Conference of the United Nations Global Navigation Satellite System, President Xi sent a congratulatory letter to the conference, the conference issued Xi'an initiative, set a new benchmark for the conference, inject new impetus; built the first The overseas Beidou/GNSS Center signed an intergovernmental agreement on Sino-Russian satellite navigation cooperation to pragmatically push the Beidou system to go out.

Fourth, high-precision features drove new breakthroughs in application. The sales of basic products such as Beidou chips and modules exceeded 70 million pieces. The performance price was comparable to the international level. Beidou high-precision products were exported to more than 90 countries and regions. Beidou ground-based technology and product system output overseas.

Beidou system services are available all over the world, including the “Belt and Road” countries and regions.

At present, the Beidou system is stable in the orbiting satellite and ground systems. After global testing and evaluation, the system performance meets expectations and has global service capabilities. Today, the new Beidou System Open Service Performance Specification (version 2.0) is released simultaneously. Beidou system service performance is:

System service area: global;

Positioning accuracy: 10 meters horizontally and 10 meters high (95% confidence);

Speed ​​measurement accuracy: 0.2 meters per second (95% confidence);

Timing accuracy: 20 nanoseconds (95% confidence);

System service availability: better than 95%.

Among them, in the Asia-Pacific region, the positioning accuracy is 5 meters and the elevation is 5 meters (95% confidence). The Beidou system services are available to all parts of the world, including the “Belt and Road” countries and regions.

The Beidou system has become one of the important achievements of China’s 40 years of reform and opening up.

The Beidou system has become one of the important achievements China has made in the past 40 years of reform and opening up. At present, the Beidou system has been widely used in China's national economy, national defense security, and people's lives. At the same time, it has benefited from the country and benefited the world. It has made great progress and remarkable benefits.

First, the scale of the industry has continued to grow and the competitiveness has increased significantly. China's satellite navigation and location services have reached 14,000 units, employing more than 500,000 people, forming the five major industrial areas of the Pearl River Delta, Beijing-Tianjin-Hebei, Yangtze River Delta, Hubei, Henan, Sichuan and Shaanxi, and growing a number of powerful satellite navigation. enterprise. With the independent Beidou chip entering the 28-nanometer process, the total number of satellite navigation patent applications in China has reached 54,000, ranking first in the world.

Second, the application field is constantly expanding and the scale is changing with each passing day. Applications in transportation, marine fisheries and other fields have continued to deepen. There are 6.17 million road operating vehicles, 35,600 postal and express vehicles, 36 central buses, 80,300 inland navigation facilities, and 2,960. Marine navigation facilities using the Beidou system. The Hong Kong-Zhuhai-Macao Bridge adopts the Beidou high-precision deformation monitoring system to effectively ensure the safe operation of the bridge. Based on Beidou's high air image detection system, it can effectively improve the quality of China's medium-term weather forecast. In terms of mass application, Beidou has realized large-scale application on smart phones. Most of the smartphones sold in the domestic market support Beidou positioning function; 2 million Taipei bucket passenger cars are equipped with intelligent vehicle terminals, and more than 10 car companies in China 30 Batch application on multiple models; intelligent driving production cars based on Beidou high-precision service are expected to be launched in 2019.

Third, the internationalization achieved new breakthroughs, and Beidou won wide overseas praise. Asian countries such as Myanmar, Laos, Cambodia, Thailand, Indonesia, Pakistan, Kuwait, Algeria, Uganda and other African countries, as well as Russia, Maldives and other countries, have successively purchased the Beidou products of Chinese enterprises. The service performance and product quality of Beidou system have created a reputation in the local area. . Beidou has entered international international civil aviation, international maritime affairs, international mobile communications and other international organization standards. ICAO has approved the Big Dipper-based enhanced service provider identification number and standard time identification number. The International Search and Rescue Satellite Organization has incorporated Beidou into the global satellite search and rescue system plan. Global users provide distress alert services.

In addition, Beidou system has been well applied in smart cities, disaster reduction and disaster relief, agriculture, forestry and fisheries, meteorological environment, precision machine control and other fields, resulting in significant economic and social benefits.

Beidou provides global services, which is a big step in the construction of Beidou and a new starting point for the development of Beidou. It welcomes new opportunities and faces new challenges.

According to the plan, the global network construction of Beidou No. 3 will be completed in 2020. In 2035, a more comprehensive, more integrated and smarter national integrated positioning and navigation time (PNT) system will be built with the Beidou system as the core. China is willing to share the achievements of the Beidou system with all countries in the world. Beidou will serve the world and benefit the people with stronger functions and better performance.
