Pujiang-2 & Tiankun-2

The Pujiang-2 satellite was developed by SAST for scientific experimental research, land and resources census, and other tasks.

The Tiankun-2 satellite was developed by the Space Engineering Group of the second academy of China Aerospace Science and Industry Corporation (CASIC) for "experimental verification of space environment sensing technology". Tiankun-2 is the successor of the Tiankun-1 satellite launched in 2017, which tested the performance of a small satellite bus. This new satellite inherits the "high functional density" of the previous satellite, while being smaller and lower cost, and will verify new attitude and orbit control algorithms, multifunctional flexible cladding materials, and computational optical imaging.
