About MSCI
MicroWheel 1000


The MicroWheel 1000 (MW 1000), part of MSCIís High Performance Attitude Control product line, is a reaction wheel torque actuator and angular momentum storage device for mini-satellites and microsatellites. The 1000-series MicroWheel is for satellites requiring less than 1000 mNms of momentum storage.

The MicroWheel is a ďsmartĒ sensor/actuator pair. It includes both a reaction wheel, and an optional solid-state angular rate sensor, both of which are operated locally by an embedded micro-controller. The micro-controller implements local speed and torque control loops for the reaction wheel, allowing the reaction wheel to accurately track speed or torque commands from a satellite's attitude control computer.

MSCI is proud of the extensive flight heritage our world-leading MicroWheels have gained.


MSCI's MW 1000 MicroWheels provide a simple, drop-in solution to satellite control. With their serial data interface, the MicroWheels perform all motor control tasks internally to generate precisely the torque requested by the Attitude Control System (ACS) computer.


MSCIís world-leading MW 1000 MicroWheels enable satellite designers to vastly improve microsatellite-pointing capabilities.

The MW 1000ís key capabilities include:

  • Spaceflight-proven design
  • Low power consumption
  • All in one control and navigation solution (with optional rate sensor)
