Trillian-1 Datasheet Product enquiry Trillian-1 cad model

Reaction Wheels

For maximum accuracy & reliability. The Trillian-1 Reaction Wheel provides high reliability, adaptability, and accuracy making it a one-of-a-kind product for Small Satellite missions.

The Trillian-1 has proven performance and reliability. The product is tested to NASA GEVS acceptance levels and features input filters that aid to reduce signal noise while a dedicated motor driver control circuit commands the Reaction Wheel safely. Designed for constellation deployment, each wheel produces a nominal 1.2 Nms momentum storage and 47 mNm maximum torque in a 1.5kg package and features three operations modes; Torque, Speed, and Direct DAC control.

Heritage

Trillian-1 has flown since 2019 with over 10 units sold. The design is based on around AAC Clyde Space’s extensive reaction wheel development experience proven across 10s of satellites. Each unit features integrated sensor and communications noise filters to increase accuracy and proprietary protection circuitry based on years of subsystem design experience ensuring the Trillian-1 will provide unparalleled mission assurance.

Adaptability

The Trillian-1 is constellation-ready and optimized for volume manufacturing and testing to support the next generations of constellations. The solution features a wide range of telecommands and telemetries providing direct access to the variables that control it for maximum flexibility if additional functionality is required over the initial 3 operation modes offered (Torque, Speed or Direct DAC control).

Durable

Designed and extensively tested for the harshness of space. The Trillian-1 reaction wheel can operate at temperature ranges of -40°C to 85°C at an absolute pressure of 1000 mbar. Each unit is tested to NASA GEVS Acceptance levels prior to shipment ensuring the Trillian-1 can survive a wide range of launch loads, offering flexibility in mission configuration.
