ADCS SERIES
Attitude Determination and Control System
The TensorADCS series provides attitude determination and control systems for nanosatellites up to 30 kg. Each system incorporates one or more variable-speed, single-gimbal Control Moment Gyroscopes (CMGs) for attitude control and maneuvering.
Available in configurations from 3U to 16U platforms, each system includes onboard attitude determination, automated operating modes, and user-configurable interfaces. Configurable systems are available to match specific mission requirements.
Operating Modes
Basic (without CMG)
- Sun Pointing
- Detumbling
- Safe Mode
Advanced Operation (with CMG)
- Target Tracking
- Fine Pointing
- Local-Vertical-Local-Horizontal
Basic Modes (Magnetorquer Control):
Sun Pointing: Maintains solar array orientation for power generation
Detumbling: Stabilizes rotation after deployment or anomalies
Safe Mode: Autonomous protection during spacecraft upsets
Advanced Modes (CMG-Enabled):
Target Tracking: Continuous pointing at ground targets during overflight
Fine Pointing: High-precision attitude hold for imaging or optical communications
Local-Vertical-Local-Horizontal: Earth-referenced nadir orientation for ground coverage

INSTALLATION
INTERFACES
The ADCS is available in integrated or discrete configurations to accommodate different satellite architectures.
1) Integrated assembly mounts in the tuna-can occupying 0.25U and maximizing internal payload volume.
0.25 U for installing in the tuna-can
2) Discrete configurations allow separate installation of CMG, controller, and sensors within the satellite structure occupying 0.75U total and providing flexible component positioning for non-standard layouts.
0.75 U for installing inside the CubeSat
Scalable and Modular
