Key highlights

The TensorCMG Series features variable-speed, single-gimbal CMGs driven by spherical motor technology, available in single and clustered configurations for satellites from 30 kg to 1000 kg.

This spherical motor design reduces weight, volume, and power consumption (SWaP).

An autonomous torque calculation algorithm is integrated on the control board, enabling multi-axis torque output through simple commands.

Applications

Earth Observation: The system's fine-pointing capabilities enable high-precision imaging and data collection of Earth's surface.
Precise Maneuvering: The TensorCMG facilitates accurate satellite orientation adjustments, essential for tasks such as target tracking and alignment with communication links.
Autonomous Operations: With embedded attitude determination and control algorithms, the system supports autonomous modes like sun pointing, detumbling, and safe mode, reducing the need for extensive ground intervention.
