Composition and Significance of Badge of China Beidou Satellite System.

The symbol of Beidou satellite navigation system consists of a round and freehand Taiji fish of yin and yang, the Big Dipper, a grid-like earth and Chinese and English characters.

The circular configuration symbolizes the "perfection" in China's traditional culture, and the deep blue space and light blue earth represent the aerospace industry. Yin and Yang Taichi Fish contains the traditional culture of China.

The Big Dipper is the basis that people have used to tell the direction since ancient times. Sina is the earliest navigation device in the world invented by China in ancient times. The combination of the two not only shows the achievements of ancient science and technology in China, but also symbolizes the industry characteristics of satellite navigation system, providing people with positioning, navigation and timing services. At the same time, it also implies the name of China's autonomous satellite navigation system-Beidou.

Grid Earth and Chinese and English characters represent the openness, compatibility and global service of Beidou satellite navigation system.
