High accuracy inertial pointing
CubeSats have evolved to the point where high accuracy inertial pointing has become a requirement in certain missions. In these missions, three reaction wheels are required to provide 3-axis control throughout the entire orbit. Sensors are chosen to provide the level of accuracy required for a specific mission. We have developed a 3-axis system that builds on the experience and hardware heritage gained from the Y-Momentum unit. This system can be upgraded to a variety of levels to provide different pointing abilities for different missions and satellite sizes.

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 in the orbital plane by controlling the momentum wheel’s speed
- Perform 3-axis pointing in any direction
The performance of the system depends 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), (iv) Sensor placement and availability during operations.
