Overview

AST's miniaturized nitrogen cold gas thrusters provide a thrust of 42 mN at more than 69 s specific impulse. The fast switching thruster allows very small impulse bits of 110 µNs. Combined with its exceptional lifetime of more than 1 billion (10^9) actuations this opens up new operational modes of small satellite fine control.

The thrust level is linear with the inlet pressure. Together with our electronic pressure regulator it is possible to adjust the thrust level in flight. The CGT has been fully qualified in the frame of the FORMOSAT 5 mission
