”——国防科技大学导航与时空技术工程研究中心创新发展记事 Xinhua News Agency, Changsha, December 29th, title: " Building the Beidou cause well is the only reason for our existence "-Notes on the Innovation and Development of the Navigation and Space-Time Technology Engineering Research Center of National University of Defense Technology


Xu Yi, Yan Zhiwen


The Navigation and Space-Time Technology Engineering Research Center of the School of Electronic Science and Technology of National University of Defense Technology has insisted on independent innovation for 24 years, and has successively broken through a series of core key technologies represented by Beidou-1 rapid acquisition and signal reception, Beidou-2 satellite anti-interference, and Beidou-3 core signals. , Won the National Science and Technology Progress Special Award, one second prize, nearly one hundred national defense patents and national invention patents.


Independent innovation is always on the way


On November 7, Wang Feixue, the leader of the Beidou team at the National University of Defense Technology, and his comrades together greeted the long-awaited "children": Beidou-1 digital fast capture and signal receiving system equipment. After 12 years of uninterrupted and stable operation, this equipment known as the Beidou System “Clairvoyance” retired and returned to its “hometown” in Changsha.


Over the years, this center has continuously climbed the peak of innovation and achieved a series of key technological breakthroughs and original results.


务中发挥了重要作用; Break through the problem of miniaturization of terminals in system applications and successfully develop practical handheld user machines, which played an important role in China's earthquake relief, rescue and rescue, border patrol and other tasks ;


Break through the two technical problems of "satellite anti-jamming" and "system high-precision measurement" in system construction, successfully developed satellite signal transmission and reception service load, and ground transportation control system main equipment, and played a major role in the construction of Beidou system;


Achieve technical coverage of the entire system, system, and link, and continuously refresh various performance indicators to make Beidou system better signal transmission and reception, more accurate time positioning, higher service accuracy, lower transmission power, larger service capacity, and terminal equipment smaller……


The world has never enjoyed the achievements of innovation. As the witness and founder builders of the Beidou cause, they have overcome all technical difficulties with their persistence and tenacity on the road.


The overtime record on the electronic screen in the central lobby witnessed their efforts and struggles: Chen Lei, Huang Xinming, and Zhang Ke averaged over 900 hours of overtime a year; Li Baiyu, Huang Long, and Liu Zhe traveled an average of 190 days a year ...


"BeiDou 1 to BeiDou 3 is a leap from stream to ocean. Persisting in independent innovation and struggling to overcome difficulties are the soul of our leapfrog and the cornerstone of our future integration of space-time challenges." Wang Feixue said, OK, that's the only reason we exist. "


Quality is life, quality is odds


In 2017, the lecturer Chen Lei found that some indicators were defective when a project was tackled. At this time, the task period was over half, and overturning it may not complete the task on time and even affect the construction of the Beidou III system. Overturned or reluctant to cross?


The same torment, associate researcher Tang Xiaomei also encountered in the Beidou-2 project. At that time, endless problems left the team in the shadow of frustration.


Never lowering the bar because of so many difficulties, they made the same choice: overturn.


"We have strong technical support, and the difficulties are not terrible. The greater challenge comes from quality control." Liu Xiaohui, the chief quality engineer of the center, said, "Without a strict quality control system and processes, everything may return to zero."


Carry out scientific research management innovation, implement a matrix scientific research organization model, and establish a "three-line" control system for the command line, technology line, and quality line ... This center implements the concept that quality is life and quality is the odds, and iteratively improves the quality gradually. Control system.


In accordance with the service target requirements of Beidou III before the end of the year, the progress of the network project undertaken by the center this year has been advanced by an average of 2 months, with tests being delivered almost every day. "'Catch the quality, do not let down, grasp the progress every second' is not a slogan." Researcher Sun Guangfu said, "Ensuring that the project will run without obstacles for the next 10 years is our bottom line."


On December 27, the construction of the Beidou III basic system was completed and services were provided to the world. After the excitement, the center personnel continued to invest in the actual combat of the Beidou system and its innovative technology research.


Cohesive Innovation Team


In August this year, external employee Mao Erkun was hired as a senior expert.


From the "small workshop" of several people to the "big team" of nearly 300 people, two-thirds of the center's external staff have covered 24 years, covering various positions such as technology research and development, comprehensive management, logistic support and so on.


At one time, two Beidou-3 satellites had signal failures one after another, and the comrades responsible for tackling the problem rushed to tears. There was no blame, the center leaders took the initiative to take responsibility, the project teams' professional groups supported each other, gathered intelligence to solve the problem, and completed the system on-orbit upgrade in just 3 months to ensure the stable operation of the satellite.


"Difficulties are always present from the demonstration of the scheme to the practical implementation." Professor Ou Gang said, "But we never fear, we win with victory, and we fight with defeat."


In recent years, the center has insisted on not deciding on qualifications and levels, and leaning towards front-line strugglers in terms of doctoral stay, professional title selection, merit awards, and performance evaluation. Performance evaluation gives priority to front-line personnel who work harder overtime, winners who receive awards first, outstanding contributions, and leading cadres to actively give up their qualifications for awards to young strugglers ...


The team members who resolved their worries were open-minded and boldly innovating, which gave birth to a new source of growth. "This is a home-like team. Here we have a proud Beidou cause and a united team culture." He Shengchun, an external employee, said, "It's difficult for me to give up."
