The VEOWARE SPACE MiniCMG is a control moment gyroscope (CMG) suitable for satellites above 250kg.

A control moment gyroscope (CMG) is an attitude control unit (actuator) consisting of a spinning rotor (also referred as a fly wheel) and one or more motorized gimbals that tilt the rotor’s angular momentum. As the rotor tilts, the changing angular momentum causes a gyroscopic torque that rotates the spacecraft.

All Veoware CMGs can be assembled in different configurations to meet various mission requirements, unlocking quick access to off-nadir angles to increase chances of refreshing the desired target. As an example 4x MiniCMG offer angular momentum storage (roll, pitch, yaw) of 9 N m s and a maximum torque greater than 14 N m.

Veoware can tune the orientations of CMG to offer preferential directions. For example, force vector and CoG misalignment direction to always have the max momentum capacity available.

Engineering models will be available in Q3 2021 while the production of flight models is scheduled for Q3 2022.

Veoware also offers MicroCMG for smaller satellites (50kg - 250kg).
