Shiyan 6 (SY 6, Experiment 6) is an experimental Chinese satellite reportedly for studying the space environment.

Jiading 1 or OKW 01 is a privately designed LEO (Low Earth orbit) communications satellite prototype for a planned constellation. The satellite was developed by Shanghai Ok Space Co Ltd, also known as Space OK, with the satellite described as China's first privately designed low Earth orbit (LEO) communications satellite. Jiading-1 is based on the company's OKW-Sat-50 satellite platform with a total mass of 45 kg and is the first satellite for the planned Xiangyun constellation for Internet of Things connectivity.

Tianping 1A and Tianping 1B are experimental Chinese satellites for ground equipment calibration purposes. The satellites are based on the Pina satellite platform. The TP-1A satellite provides a radar calibration target (?), and the TP-1B provides calibration services for responsive control equipment.

Tianzhi 1 is an experimental Chinese satellite developed jointly by a number of institutes under the Chinese Academy of Sciences (CAS) and the China Academy of Space Technology (CAST) as a test satellite to be used to verify the key technologies of software-defined satellites. The satellite has a mass of 27 kg according to China News Service (Chinese), with payloads including a small cloud computing platform and a camera. Tianzhi-2 was expected to launch in the second half of 2019 but has been delayed.
