WHL-200

Very low microvibration results after after random vibration, shock and thermal testing enabling fine pointing accuracy.

In GEO orbit since March 2023. Based on technology with accumulated space heritage from multiple missions.

Providing a Momentum capacity of 200 mNms and offering a torque up to 20 mNm, with a mass of 423 g and volume 70 x 70 x 45 mm³. Power cosumption optimized for less than 1.5 W at nominal Momentum.

This space qualified wheel offers state-of-the-art design: low magnetic residual, very high radiation shielding, firmware updates in space. The rotor is axially suspended between two hybrid ceramic high precision bearings chosen for long life and low friction in extreme conditions.
