It was developed under the direction of Qian Xuesen (Tsien Hsue-shen), dean of the Chinese Academy of Space Technology (CAST). At the time, a total of five identical satellites were created. The first satellite launched successfully. The academy formulated a "Three-Satellite Plan" consisting of "Dongfanghong I", re-entry satellites, and geosynchronous orbit communications satellites. Sun Jiadong was responsible for the "Dongfanghong I" technology. In 1967, Dang Hongxin chose a copper antenna membrane that resolved the difficulties of broadcasting on an ultra-short wave antenna between 100 °C and −100 °C. Engineers installed a music player playing "The East is Red" on the satellite.
