CubeControl is an actuator and sensor interface module for nanosatellites with advanced attitude control requirements. It is capable of controlling magnetorquers and a momentum wheel. It can also interface with magnetometers, coarse sun sensors, and rate sensors. The module can be configured to include any desired combination of actuators and sensors, depending on the mission requirements.
