200SP-M Smallsat Wheel


Surrey's Small Satellite 200SP-M Reaction Wheel provides a high agility and control solution for Earth Observation missions and is suitable for LEO and MEO. The 200SP-M wheel has its own microprocessor which provides low level control and data interfaces.

Including one wheel in your design will provide single-axis momentum bias; three wheels in orthogonal axes will provide three-axis zero-momentum control. Fly four 200SP-M wheels in a tetrahedral configuration to provide control redundancy.
