Control Moment Gyroscope

The CMG Series sets a new standard in nanosatellite attitude control, offering various benefits over reaction wheels. With a design focusing on reduced weight, volume, and power consumption, our gyroscopes deliver a performance that competes with and often surpasses advanced actuators. Our Control Moment Gyroscopes (CMG) stand out due to their variable-speed, single-gimbal configuration, granting multi-axis torque output for accurate attitude corrections. An autonomous torque calculation algorithm is embedded on the control board, enabling a full control of the complex dynamics of the CMG through simple commands. Our solution ranges from the compact CMG-10m specifically designed for CubeSat applications and can be combined for missions up to 16U, to our CMG-1 for larger satellite platforms up to 100kg. With the CMG Series, we invite you to experience the additional agility and performance that CMG can bring to your missions while maintaining a high level of accuracy, ushering in a new era for ADCS systems.

A spinning rotor (or flywheel) lies at the heart of a CMG. This rotor is kept spinning at a variable speed by a motor. The faster the rotor spins, the more angular momentum it possesses. The spinning rotor is mounted inside a gimbal frame, allowing the rotor's spin axis to tilt in different directions. By altering the orientation of the rotor's spin axis, we can change the direction of its angular momentum. When the orientation of the rotor's spin axis is changed (by tilting it using the gimbal), the spacecraft will experience a torque due to the conservation of angular momentum. This torque will induce rotation in the spacecraft.





Our ADCS and CMG are able to install in the CubeSat's tuna-can or structure according to the user's requirements. With special hardware design, our ADCS and CMG can fit into most of the deployer's tuna-can on the market.

1) Installing the ADCS or CMG in tuna-can is recommended, as this takes up the least space in the satellite.

0.25 U for installing in the tuna-can

2) However, it is feasible to install the ADCS or CMG within the cubesat structure shown in configuration 2.

0.75 U for installing inside the CubeSat




ADCS-10m is an integrated ADCS with a variable speed control moment gyroscope (CMG) which is suitable for satellites up to roughly 3U. This module can be installed within the tuna can or the satellite structure.
