Tianqi (also transcribed Tiange) is a series of small Chinese experimental LEO comsats by Guodian Gaoke for IoT (Internet-of-Things) communications, which are also carrying a camera for educational purposes.

Guodian Gaoke plans to operate an IoT constellation. The "Apocalypse Constellation" provides users with much-needed data collection and transmission services for terrestrial network coverage blind areas, which are widely used in marine, environmental protection, meteorological, forestry, geological, emergency, rescue and smart city industries to enhance China's global data network coverage and application capabilities are of strategic importance.

Tianqi 8 was launched in December 2020 as a co-passenger on the maiden CZ-8 (1) rocket. It is larger than the earlier Cubesat based Tianqi satellites.

Tianqi 9 was launched in April 2021 as a co-passenger on a CZ-6 rocket.
