His most important contribution was developing three-axis stabilization for the attitude control systems of recoverable satellites, and he also developed control systems for rockets and nuclear weapons testing. He was elected a delegate to the Third, Fourth, and Fifth National People's Congresses.

In March 1986, Yang and three other prominent scientists—Wang Daheng, Wang Ganchang, and Chen Fangyun—wrote a letter to Deng Xiaoping advocating the development of strategic technologies.

Deng accepted their proposal, which gave birth to the influential 863 Program, named after the date of their letter.

Yang died in Beijing on 11 June 2006 at the age of 86. He was buried at the Babaoshan Revolutionary Cemetery.
