BY 3 or Taiyuan (sometimes also called BY70 3) is a microsat project led by China Center for Aerospace Science and Technology International Communications for school education and amateur radio. Students from the Beijing Bayi High School built the satellite under the instructions from experts.

BY 3 is a microsat with less than 40 kgs and 196×190×315 mm. The BY70-3 satellite is one of a series of public welfare science education satellites launched by China center for Aerospace Science and Technology International Communications in cooperation with Taiyuan Jinshan Middle School and other schools, which are not commercial sources of funds. It is aimed at developing science education in space for primary and secondary school students around the world. In order to facilitate the operation and practice of students from all over the country and the world, the satellite plans to set up a space amateur frequency band communication payload for students to understand and practice the principle of satellite operation and control.

The satellite was launched on 6 November 2020 on a CZ-6 rocket as a piggy-back payload.
