ADCS-MTQ Integrated Attitude Determination and Control System

ADCS-MTQ uses a triaxial magnetometer and a triaxial magnetorquer for attitude control. Its control modes include magnetic dipole moment control and de-tumbling.

To enable the sun-pointing mode, 6 optional FSS-15 fine sun sensors must be installed on the user's satellite. For users who desire to build their own ADCS, they may use our ADCS-MTQ as magnetic sensors and actuator components only.

Its ADCS system functions can be triggered on orbit and serve as a backup ADCS when the user finds the primary ADCS failed. Moreover, support software is provided for the user to set up and calibrate the system.

For 1U to 3U CubeSats with a limited power budget and volume constraint, this magnetorquer-based ADCS will suit your application.
