The first rocket was launched at 1970. Long March 1 is a three-stage launch vehicle developed by China in the early 1970s, which is used to launch China's first artificial earth satellite. The first and second stages of Long March 1 adopt liquid fuel engines, and the third stage adopts solid fuel engines.

The rocket was developed in 1965, launched for the first time on April 24th, 1970, and successfully put Dongfanghong-1 into orbit, and launched for the second time on March 3rd, 19765438, successfully put Shi Jian-1 scientific experimental satellite into orbit.

The Long March 1 guidance system adopts the scheme of position strapdown compensation longitudinal guidance plus coordinate transformation transverse guidance and normal guidance. When the second-stage rocket is shut down, the guidance system controls the shutdown parameters, so that the third-stage rocket slides to the predetermined ignition position and has an accurate initial ignition speed. The guidance system consists of accelerometer, digital computing device, analog computing device and transverse normal instrument. In addition, the guidance system also receives signals from the horizontal gyroscope and the vertical gyroscope.
