Beidou satellite navigation system is a global satellite navigation system independently built and operated by China focusing on the needs of national security and economic and social development. It is an important national space-time infrastructure that provides all-weather, all-time and high-precision positioning, navigation and timing services for global users. *** Since the Beidou system was completed and put into operation one year ago, its operation has been stable and its performance has improved steadily. It continues to meet the needs of global users. It has become a vivid case of China actively promoting the construction of a community with a shared future for mankind with practical actions. Win win cooperation: adhere to the coordinated development with other satellite navigation systems. As a core supplier recognized by the global satellite navigation system committee of the United Nations Department of foreign space, Beidou system has adhered to the development principle of "openness and compatibility" since the beginning of construction, and has cooperated with the United States and Russia on Beidou system, GPS GLONASS signed bilateral agreements on compatibility and interoperability between systems, and continued to promote compatibility and interoperability coordination between Beidou system and Galileo system with the EU.

Since 2014, China and the United States have established a dialogue mechanism for satellite navigation cooperation, signed the statement on China US satellite navigation system (Civil) cooperation and the joint statement on compatibility and interoperability between Beidou and GPS signals, and Beidou signals and GPS signals have achieved interoperability. In early 2015, under the framework of the regular meeting committee between Chinese and Russian prime ministers, the Committee on major strategic cooperation projects in satellite navigation between China and Russia was officially established, laying a solid foundation for deepening cooperation between the two systems; The agreement on cooperation in the peaceful use of Beidou and GLONASS global satellite navigation systems and other outcome documents were signed, providing an organizational guarantee for the complementary advantages and integrated development of the two systems. Carry out several rounds of talks with the EU, continue to promote the frequency coordination between Beidou and Galileo systems, and jointly promote the provision of better satellite navigation services for users around the world. Today, one of the four satellites embedded in the logo of the United Nations International Committee on global satellite navigation systems represents China's Beidou. Dr. mazlan Osman, former director of the United Nations Department of outer space, said that "China has played a leading and exemplary role in the field of satellite navigation".


At present, the fusion application of multiple satellite navigation systems has become an important development trend. In the future, China will always adhere to the concept of a community with a shared future for mankind, continue to actively and pragmatically carry out coordination and cooperation with other emerging satellite navigation systems, work hand in hand to provide global users with higher performance, more reliable and richer services, so that satellite navigation can better benefit people's livelihood and serve human development and progress. *** Beidou system is a typical public product of China's practice of "allowing people of all countries to share development opportunities and achievements".


In November 2018, the 13th General Assembly of the United Nations International Committee on global satellite navigation systems was held in Xi'an, China. *** The Beidou system, which is transparent, open and embracing the world, has successively signed bilateral cooperation agreements such as China Pakistan, China Thailand, China Russia, China Saudi Arabia, China Arab League (League), China Iraq (LAC) and China Arab (Genting), and established normalized exchange platforms such as China ASEAN Beidou Cooperation Forum, China Arab Beidou Cooperation Forum and China Central Asia Beidou Cooperation Forum, China's Beidou has become a bright business card for the country's foreign exchanges.


In order to meet global application needs, the Chinese government continues to promote Beidou to enter the standard system of international organizations such as civil aviation, maritime affairs, search and rescue satellite, mobile communication and Electrotechnical Commission. So far, a number of international standards supporting Beidou have been issued, the international mobile communication organization has issued 5g standards supporting Beidou signal, the International Maritime Radio Technical Committee has also issued differential data standard protocols supporting Beidou signal, and the International Electrotechnical Commission has issued international standards for the detection of Beidou shipborne receiving equipment. Beidou is going global with 5g, civil aviation, navigation and other industries.


At present, Beidou system has been applied in more than half of the countries and regions around the world, providing services to more than 100 million users. Various solutions based on Beidou, such as land ownership confirmation, precision agriculture, digital construction, disaster prevention and mitigation, smart port, etc., have been applied in many countries in ASEAN, South Asia, Eastern Europe, West Asia, Africa and other regions. Beidou international cooperation strengthens technical cooperation and exchanges in the field of satellite navigation with partner countries through testing and evaluation, technology R & D, application demonstration, education and training, so as to benefit people's livelihood, serve social development and achieve common progress. Build consensus: build a fair and reasonable satellite navigation international order. Beidou system always adheres to systematization, promotes the construction of Beidou rule of law, and escorts the healthy development of Beidou system. At the same time, China actively participates in international activities under the framework of the United Nations and other international organizations and relevant multilateral mechanisms, adheres to the international order and creates a fair and reasonable international legal environment for satellite navigation.


Since the construction of Beidou system, China has followed the rules of the International Telecommunication Union, carried out the application and coordination of satellite navigation frequency, and legally used frequency orbit resources; Actively fulfill international responsibilities and work with other countries to promote S-band to become a new satellite navigation band.


China actively assumes the responsibility of a major satellite navigation country and advocates the formulation of fair and equitable international rules in the field of satellite navigation. In 2019, at the 14th session of the United Nations International Committee on global satellite navigation systems, China shared its experience and practices in the construction of the rule of law in satellite navigation, and advocated countries to strengthen cooperation on the rule of law in satellite navigation, so as to promote the formation of global consensus It has contributed to improving global governance of satellite navigation.


At present, the international situation is becoming more and more complex. It is imperative to promote the construction of a more just and reasonable international order of satellite navigation. China will continue to actively participate in the formulation of international rules for satellite navigation, strictly fulfill the obligations of global satellite navigation system suppliers, continue to adhere to the principle of joint consultation, joint construction and sharing, and jointly write international rules for satellite navigation with countries all over the world, so as to provide institutional guarantee for Beidou system to better serve the cause of human progress and promote the development of global satellite navigation.


Looking up at the starry sky, the Beidou is bright. After 27 years, Beidou system has mobilized thousands of troops, experienced thousands of hardships and hardships, and entered thousands of families. Looking forward to the future, the journey is long. China Beidou serves the world, which is not only the original intention of Beidou system, but also the historical mission entrusted to Beidou system by the times.
