Research on Microgravity Measurement Technology of Manned Spacecraft

In the paper, the requirements of microgravity measurement for space science experiments carried out by the payload of manned spacecraft was analyzed, and the microgravity measurement technical scheme of manned spacecraft was put forward. At last, the microgravity data measured during manned spacecraft in orbit were deeply studied. The research result can provide an important reference for the monitoring and control of microgravity environment of manned spacecraft in China.
