On October 31st, Class 1 of 24 Telecommunication classes in the School of Electronic and Information Engineering carried out a face-to-face activity of tutors (head teachers) in the meeting room of Linjiang Building. The theme of this lecture is the principle of satellite navigation and positioning technology, the speaker is the head teacher Xie Yaqin, the instructor Zhang Weidong and all the students of the class attend the lecture, the lecture is presided over by the monitor Ding Weijian.
At the beginning of the lecture, Xie Yaqin briefly introduced the importance of satellite navigation and positioning technology, and emphasized the wide application of this technology in modern life, especially in transportation, communication and military fields. She introduced the core content of navigation technology in detail from three aspects. She explained the classification of navigation techniques, including biological navigation, inertial navigation, signal based navigation, etc. She also singled out the Global Positioning System (GPS) and China's Beidou navigation system, highlighting the differences in how these systems provide location information. She also delved into the process of transmitting and receiving satellite signals, explaining how satellites move in orbit and transmit radio signals, and how terrestrial receivers analyze the received signals to determine their position. She mentioned that the transmission of the signal is affected by the atmosphere, so it needs to be calculated and adjusted accordingly.
At the end of the lecture, Xie Yaqin summarized the application prospect of satellite navigation technology, and encouraged students to pay attention to the study of professional basic knowledge in the future study, so as to better understand and master the related technology in the field of communication.
The lecture not only deepened the students' understanding of satellite navigation and positioning technology, but also stimulated their enthusiasm for continuing to study the professional direction, laying a good foundation for the later professional course learning.
