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 that 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, opening up a new era for ADCS systems.

A spinning rotor (or flywheel) is 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 has. The spinning rotor is mounted inside a gimbal frame, which allows the rotor's spin axis to be tilted in different directions. By changing the orientation of the rotor's spin axis, we can change its angular momentum's direction. 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 cause the spacecraft to rotate.





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.

install in the bottom of 3U+/6U+ satellite # occupied volume 0.4U

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

install in the middle of cubesat # occupied volume 0.4U




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.
