 General designer of Beidou satellite navigation system engineering on global constellation deployment


Yang Changfeng, chief designer of Beidou satellite navigation system engineering: I am very excited about the successful launch. Novel coronavirus pneumonia is no danger of anything going wrong. The launch is completed in the global context of the fight against the new crown pneumonia. The project is to ensure that the mission is successful, and we must also grasp the epidemic prevention and control to ensure that two success is assured.

It is not easy for beidou-3 to succeed in successive 18 launch missions. In two and a half years, with the concerted efforts of more than 400 participating research and construction units and more than 300000 scientific and technological personnel, Beidou has successfully completed this task. It is not easy for every Beidou person to participate in the task. It is not easy for our gold rocket to ensure the success of the Beidou mission, nor for our home port to ensure the success of the Beidou mission.

The success of this mission once again shows that the whole Beidou team is a team that can fight hard battles. We will always cherish the feelings of Beidou, be careful and never forget our original intention. The final realization of the strategic goal of three steps reflects the spirit of Beidou in the new era.

Peoples daily economic and social: you said before that you are full of confidence in this launch. Where does your confidence come from?

Yang Changfeng: building a good Beidou system is our first mission. For more than 30 years, Beidou people have been pursuing excellence, being careful all the time, not neglecting any detail, and not letting the satellite bring any tiny problem to the sky.

Peoples daily economic and social: from Chinas Beidou to the worlds Beidou. You said at this years two sessions that this is Chinas plan and Chinas wisdom. How to reflect it?

Yang Changfeng: the construction and development of Beidou system fully combines Chinas national conditions with Chinese characteristics, which is also our China plan for the development of satellite navigation in the world. In 2000, China built Beidou No.1 system to provide services for Chinese users; at the end of 2012, China built Beidou No.2 system to provide services for users in the Asia Pacific region. However, the construction of Beidou system did not stop. In November 2017, the first group of double stars of beidou-3 was successfully launched. Beidou system has entered the era of globalization. Today, the deployment of global constellation of beidou-3 system is completed, and beidou-3 system is about to complete the global networking and realize the dream. Chinas Beidou will truly become the worlds Beidou and provide high-precision services to global users.

In Chinas three step development strategy, we use Chinas wisdom to innovate and adopt GEO / IGSO / MEO three orbital hybrid constellations to achieve regional services with the minimum number of satellites and support the construction while building and promoting construction. While serving the world, we can also achieve regional enhancement and high comprehensive benefits of engineering construction. In addition, in the Asia Pacific region, through the use of three kinds of orbit satellites, users can enjoy the medium and high orbit navigation satellite services at the same time. The satellite has high elevation angle and strong anti blocking ability. In the multi-level urban canyon and tree sheltered environment, users can still obtain continuous navigation services, which improves the accuracy, continuity and availability of satellite services.

Peoples daily economic and social: the global networking of Beidou system is about to be completed. What will be the focus of the next work?

Secondly, the overall application of Beidou system. The important purpose of Beidou system construction is to serve the national construction, economic development, peoples life and the application value of the national important tool. At present, Beidou application and industrial development have achieved phased results, laying a solid foundation for comprehensive application. I believe that when the Beidou system is about to be completed in an all-round way, the application of Beidou should strengthen overall planning and system promotion. The competent departments of various industries and fields shall formulate industrial policies and regulations, improve standards and specifications, and establish application product catalog, etc., so as to promote Beidou application to enter a new stage through joint efforts. As a Beidou person, my work experience has a profound brand of Beidou. I am honored to participate in the cause of Beidou and make the past decades more meaningful. It is of great significance to me that the deployment of beidou-3 global system constellation has been completed in an all-round way. But just like satellite navigation is limited by peoples imagination, I believe Beidou system will bring more surprises to the world. This is the dream we pursue. My team and I will strive for this dream. Source: Qiao JunJing, editor in charge of peoples daily_ NBJ11279
