Colibri Wireless 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 temperature influences on other sensors. Up to 10 Colibri-Wireless could be connected in the synchronous network to the single USB-dongle (receiver). Several networks may be synchronized via cable.
Sampling frequency is 100 Hz for every tracker. Supplied API for Windows and Linux implements orientation tracker.
