These are the sensors we are going to use in our experiment: an accelerometer and a 3D magnetometer module.

We will receive and analyse the information obtained from the sensors and the StarTracker camera in order to determinate the attitude. This type of orientation is very common in satellites, since it provides the position of the satellite with accuracy by measuring the magnetic field of the Earth and the inclination of the satellite with respect to it.

The model we are going to use is the LSM303DLHC, which is a system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor.
