Colibri is the Inertial Measurement Unit (IMU).
It carries 3-axis state of-art sensors to measure acceleration, angular rate and magnetic field. Built-in temperature sensor helps to eliminate temperatureinfluences on other sensors.
Colibri can output both raw sensor data and calibrated floating-point data. You may enable/disable data from any sensor and change frequency from 10 to more than 100Hz.
Supplied API for Windows and Linux implements orientation tracker. Using it you will simply get orientation data in Euler angles or quaternion form.
