Bufeng 1A and 1B is a pair of small Chinese satellites built by CAST for testing the measurement of surface sea wind velocity fields via small satellites formation flying.

The Bufeng satellites measure the velocity of the wind by measuring the signals of navigation satellites reflected on the ocean's surface (GNSS-R).

The satellite were launched in June 2019 on the first sea launch of a CZ-11H rocket.
