IMU

The Inertial Measurement Unit is built into the CubeADCS module. Precicely speaking, 2 gyros can be inside the CubeComputer. The DM has one Gyro. No acceleromenter is in this system.

Mathematical Description

The inertial measurement unit measures the satellite's rotational velocities $\vec{\omega}_m$ (gyroscope) and translational accelerations (accelerometer) in the imu coordinate frame I. The measurement model for the 3 axis gyroscope is:

The measurement model for the 3 axis accelerometer is comprised of a linear acceleration term, noise, and two centripetal acceleration terms with $\vec{x_{imu}}$ (Inertial Frame) being the position of the IMU relative to the Body frame origin expressed in the imu frame:
