The ideal solution for small spacecraft that only need to fly in a stable attitude

For the majority of CubeSat missions the payload's ADCS requirement is to be 3-Axis stabilized, with the payload pointing nadir or in the flight direction. We have developed a very robust, low-power system for achieving this using a very compact bundle of hardware components. This unit has been refined through flight experience, and this second-generation Y-Momentum bundle is truly the ADCS ‘sweet spot’ for small CubeSats.

Typical applications

The Y-Momentum bundle is used for missions where a 3-axis stable system is required but the pointing performance requirements are relaxed. The single momentum wheel provides good disturbance rejection which makes it possible to keep the satellite 3-axis stable using magnetic control.

General, low-resolution Earth observation missions

Scientific missions where the payload must be pointed in the velocity direction

Communication missions that can be improved by doing tracking in the pitch direction


The following modes are available in the default bundle:

  • Detumble the satellite and bring it to a controlled spin using the magnetorquers
  • Stabilize the attitude in the orbit using a combination of the momentum wheel and magnetorquers
  • Perform pitch maneuvers within the orbital plane by controlling the momentum wheel’s speed

Random tumble

Controlled spin

Orbit stabilized

Orbital pitch pointing

The performance of the system depends, among others, on the following items: (i) Moment of inertia and mass of the satellite, (ii) Orbital parameters (in particular the altitude and inclination), (iii) Magnetic dipoles in the satellite and aerodynamic properties (especially in the case of deployable solar arrays).
