Look up at the starry sky Big Dipper brilliant, dream of the moon Shu wide sleeves... On June 24th, the team of aerospace scientists entered the campus and the public lecture activities of contemporary outstanding Chinese scientists continued to be held at the Hong Kong Polytechnic University. Today, Xie Jun, deputy chief designer of the Beidou satellite navigation system project, chief designer of the Beidou-3 satellite, and Zhang Xi, executive director of the Chang'e-4 probe project, will bring keynote speeches.
"Looking forward to it" "As soon as the music opened, I felt my blood boiling"... The event has not yet begun, and many netizens have been waiting in the live broadcast room with expectations, and have expressed their expectations in the form of messages.
With the warm applause from the audience, Xie Jun boarded the podium of the Hong Kong Polytechnic University and began a speech with the theme of "Looking Up at the Stars and The Bright Dipper", introducing the significance of the Beidou system and the Beidou spirit in the new era. It is understood that Xie Jun is mainly engaged in the research work of Beidou satellite navigation system, satellite radio payload technology, space-based spatio-temporal reference technology and other directions, and has achieved fruitful results in the design of hybrid constellation navigation satellites, the establishment of space-based high-precision spatio-temporal datums, the generation of new navigation signals, and the construction of inter-satellite links, and has successfully completed the development and launch of Beidou-2 and Beidou-3 satellites, making major contributions to the construction and leapfrog development of China's Beidou project.
In his speech, Xie Jun shared with everyone the achievements of China's aerospace. He mentioned that the satellite navigation system is based on the measurement of time to complete its mission, and today is a period of vigorous development and wide application of satellite navigation systems. China adheres to the principle of "independence, openness, compatibility and gradualness", focuses on the needs of national security and economic and social development, and independently develops and operates satellite navigation systems as the infrastructure of China's global public services; in accordance with the "first active, then no source; first experiment, then service; first regional, then global" development.
Why do many countries want to establish independent satellite navigation systems? Xie Jun said that this is directly related to many important infrastructures in the country, such as the operation of the banking system and national security defense. "China's development of satellite navigation systems should be said to have had this idea for a long time, until today; we will unswervingly do a good job of this system in the next step."
At the event site, talking about the development history of Beidou, Xie Jun said with great emotion: "China's aerospace is the result of generation after generation, and generation after generation continues to struggle. Self-improvement, self-reliance and independent innovation are the most basic elements passed down from generation to generation. ”
