The IMU sensor used in the PIXY F is a combination of a high precision 3 axis gyroscope sensor and a 3 axis accelerometer sensor.
IMU board is being heated where the temperature inside is controlled around 50°C with 0.2°C accuracy. Thanks to this feature, gyro calibration is no longer required in most situations.
The PIXY F controller has a special algorithm to provide attitude estimation based on input data from the IMU sensor. This attitude estimation helps the controller to command motor output to compensate for camera movement.
