(1) Recently, in the ninth international interior positioning navigation competition, Wei Baoguo, chief scientist of China Electronic Technology Group Co., Ltd., led a team to achieve real -time continuous positioning of indoor targets and won a single championship. This is another wonderful appearance of the team's indoor positioning navigation. Previously, it was this team that realized the breakthrough of the Beidou room positioning navigation service "from 0 to one".

(2) Since 1995, Wei Baoguo (first from left) has taken root in the first line of Beidou scientific research. When the Beidou No. 1 project was launched, he was 29 -year -old in the field of ground system research and development. Under the guidance of old experts, Wei Baoguo and his colleagues all overnight, cut off and seized, and developed a new digital signal receiving system to help my country become the third country in the world with satellite navigation systems.

(3) The construction of the construction of the Beidou II system has begun, and the number of networking satellites has increased significantly. If an old method is used, each satellite corresponds to a set of ground antennas, and the ground station will become "antenna farm", bringing a series of hidden dangers. The Webao Guo team innovatively proposed the "Digital Multi -Polison Beam Multarar -star Metalization Technology System", that is, a ground station system generates multiple beams at the same time, tracking and managing multiple satellites.

(4) In the face of this complex technology, the Wei Baoguo team started from scratch. After three years of pre -research, five -year research, and thousands of experiments, the key equipment of the Beidou II grounding control system was finally developed- The world's first digital multi -wave beam satellite navigation measurement system ensures the successful construction and equipment application of the Beidou II system, so that the world remembers the name "China Beidou".

(5) Beidou must not only be easy to use in the sky, but also use it on the ground. Create a good Beidou system is equivalent to building a rough house, and the application can be used to achieve "refinement". Since 2016, the indoor accurate positioning has become one of the "refined decoration" projects specially attacked by the Weibao Guo team. Their cutting -edge practice lays a solid foundation for seamless navigation positioning in Beidou.

(6) With the official opening of the Global Satellite Navigation System of Beidou III, China Beidou has embarked on the stage of serving the world and benefiting human beings. Wei Baoguo still dared not relax. Every time he was on a business trip, he always carried a backpack with professional books. "If you don't study, you must be behind. I am engaged in the cause of the country. I have a responsibility to pick this burden." Wei Baoguo said.
