106 years ago today, on July 16, 1919 (June 19, 1919 in the lunar calendar), Yang Jiachi, an expert in aerospace technology and automatic control, was born. Yang Jiachi (1919-2006), expert in aerospace technology and automatic control, expert in instrumentation and automation, founder of automatic detection. One of the founders of China's automation discipline, China Automation Society and China Instrumentation Society, academician of International Academy of Astronautics, academician of Chinese Academy of Sciences. He joined the Communist Party of China in December 1980. He was born in Wujiang County, Jiangsu Province on July 16, 1919 in Wujiang County, Jiangsu Province. Graduated from the Department of Electrical Engineering of Shanghai Jiaotong University in 1941. In 1947, he went to study in the United States, studied in the Department of Applied Physics of Harvard University, and received his master's degree and doctorate degree. From 1950 to 1955, he successively served as a researcher at the University of Pennsylvania and a senior engineer at the Rockefeller Institute. After returning to China in 1956, he successively served as researcher, office director and deputy director of the Institute of Automation, Chinese Academy of Sciences, and deputy director and director of Beijing Institute of Control Engineering. After 1968, he served as deputy director of the 502nd Institute of the Fifth Academy of the National Defense Science and Technology Commission, vice president of the Fifth Academy of the Seventh Machinery Ministry and director of the 502nd Institute, and chief engineer of the Aerospace Ministry. Vice President of China Academy of Space Technology and Chief Engineer of Ministry of Aerospace Industry. In the 1960s, he participated in the formulation of China's industrial automation instruments, China's automation science and technology development plans, and the ten-year plan for the development of China's artificial satellites. In 1984, he was named a model worker of the Ministry of Aerospace. In March, 1986, together with Wang Daheng, Wang Ganchang and Chen Fangyun, he put forward suggestions that were of great significance to the development of high technology in China. With Deng Xiaoping's personal instructions and active support, the State Council formulated the "863 Plan" of high-tech development in China on the basis of listening to expert opinions, which created a new situation for the development of high technology in China. In 2000, academicians such as Wang Daheng and Yang Jiachi jointly put forward the proposal of developing my country's automotive electronic information industry and seizing the commanding heights of the world's automotive computing platform in the future. Since the establishment of the Chinese Society of Automation in 1961, he has served as the executive director of the first and second councils, the third and fourth vice chairmen, and the fifth and sixth (1993-1997) chairmen. Yang Jiachi has long been committed to the development of China's science and technology and aerospace industry. He participated in the formulation of China's space technology development plan and was one of the experts of the Chinese Academy of Sciences who carried out aerospace technology research in the early days. Lead and participate in the development of China's first artificial earth satellite attitude measurement system. The recoverable satellite attitude system and data analysis indicators developed by the leader reached the international advanced level at that time. Guide the development of major scientific research projects such as detection technology and equipment needed for atomic bomb explosion tests. Yang Jiachi participated in the establishment of the China Instrument and Control Society, which was established in March 1979. He was successively elected as the vice president of the first to fourth councils of the society. Yang Jiachi was awarded the title of Model Worker of the Ministry of Aerospace in 1984. In 1985, he won the special prize of the National Science and Technology Progress Award. Since 1990, he has enjoyed special government allowances. In 1991, he was approved by the Ministry of Aeronautics and Astronautics as an old expert with outstanding contributions. In 1995, he won the Chen Jiageng Information Science Award of Chinese Academy of Sciences. In 1999, he was awarded the "Two Bombs and One Satellite" Meritorious Medal, and in the same year, he won the Ho Leung Ho Lee Foundation Science and Technology Progress Award. On October 22, 2003, Yang Jiachi met with Chinese astronauts. Yang Jiachi died in Beijing at 12:45 on June 11, 2006 at the age of 87 due to ineffective treatment.
