Why is Zhao Jiuzhang called "the pioneer of China's space industry"

Because Zhao Jiuzhang is one of the initiators and founders of China's artificial satellite industry. He actively promotes the development of space science. Since the late 195s, Zhao Jiuzhang has devoted himself to the creation of China's space industry with great enthusiasm. In 1958, Zhao Jiuzhang was the main technical director of the Second Department of Institute of Geophysics, Chinese Academy of Sciences, and was responsible for all preparations for satellite development. In October of the same year, he put forward an important proposal that "China should take the road of self-reliance, from small to large, from low to high". During the three difficult years in the 196s, Zhao Jiuzhang adjusted its development plan in time, focusing on meteorological rockets with less investment and manpower, gradually carrying out other high-altitude physical exploration, and exploring the development direction of satellites. In the early 196s, China Academy of Sciences successfully launched a meteorological rocket. All kinds of instruments, radio telemetry system, power supply and radar tracking and positioning system in Arrow instrument cabin were developed by Geophysical Research Institute under the leadership of Zhao Jiuzhang. They also developed the Doppler velocimetry and positioning system and beacon used in the "Dongfanghong-1" satellite.

in the autumn of p>1964, Zhao Jiuzhang lost no time in submitting a formal proposal to the State Council for developing satellites, which attracted the attention of the central authorities. In March 1965, the Central Committee approved the plan put forward by China Academy of Sciences. Since October 1965, under the leadership of China Academy of Sciences, a further demonstration of the overall scheme of satellite construction has been held, at which Zhao Jiuzhang made important suggestions. Then, the 651 Design Institute, which is responsible for implementing the satellite development plan, was established, and Zhao Jiuzhang presided over the scientific and engineering work. His development planning and specific exploration scheme of China satellite series played an important role in determining the overall scheme of China's first artificial earth satellite and recoverable satellite and developing key technologies. In 1985, he won the national special prize for scientific and technological progress. Zhao Jiuzhang has made outstanding contributions to scientific research.

Zhao Jiuzhang (October 15, 197-October 26, 1968), born in Kaifeng, Henan Province, is a famous scientist, meteorologist, geophysicist and space physicist. Make outstanding contributions to China's satellite industry. After graduating from Tsinghua University in 1933, he stayed on as a teacher. In 1935, he went to study at the University of Berlin, Germany, and received his doctorate in 1938. In 1941, he served as a researcher at the Institute of Meteorology, Academia Sinica. From 1944 to 1949, he served as acting director and director. During this period, from 1944 to 1949, he served as a professor at the Department of Meteorology, School of Science, Nanjing University, teaching dynamic meteorology.
