Nanosatellite OBC

The pure magnetic ADCS unit is typically used in 1U satellites, but is not limited to them. In these satellites accurate pointing is rarely a requirement and space is very limited. This ADCS unit provides a robust, compact unit to get a 1U satellite from its initial random tumble, to a controlled slow spin. As space is typically very limited in such a 1U mission, the OBC of the ADCS unit can be unlocked to act as both ADCS and main OBC.
