reaction control system (RCS)
A reaction control system (RCS) is a type of attitude control system that uses small, low-thrust vernier engines to provide three-axis control of a spacecraft in the absence of aerodynamic forces. Most RCS systems employ a cold gas such as nitrogen, although some operate using hydrazine. Pointing accuracies of 0.1–0.5° are typically achieved.
