Chinese space program - Wikipedia

The space program of the People's Republic of China is directed by the China National Space Administration (CNSA). Its technological roots can be traced back to the late 1950s, when China began a ballistic missile program in response to perceived American (and, later, Soviet) threats.However, the first Chinese crewed space program only began several decades later, when an accelerated program ...

The Small Scientific Satellite (S 3 or Explorer-45) was one of the first satellites of this decade. Launched on November 15, 1971, its mission was to study the earth's magnetosphere (see Fig. 10). It was a small, spin-stabilized satellite, with a launch mass of approximately 52 kg, and was placed in a highly elliptical orbit of 272 km x 18,149 km at 3.2° inclination.

You could also spin up gyroscopes to save fuel on small maneuvers like the ISS does. They have their limitations, but they are much more flexible than bleeding precious mass out into the void. I'd give them a trackball control -- you only have 2 axes that matter for the purposes of aligning guns.
