A big change occured in the new board: Instead of three coils there will be one permanent magnet to align the satellite to the earth´s magnetic field.

This will have the advantage of detumbling and stabililzing the satellite.

The remaining axis can be controlled by a reaction wheel (mounted on the right side).

It´s basically a small motor which changes the rotation around the mounted axis. This axis is perpendicular to the two others magnetically stabilized axes, so you can change the camera´s perpective instantly while maintaining attitude stability.

Board is going in production asap.

The motor's magnetic field won't cause tumbling? (Its frequency is too high, maybe?)

  Are you sure? yes | no
