The building has been designed to create "horizontaldrift" between disciplines, and the creative processes take place in highly visible proximity to one another.
Horizontal gyro drift is measured in state of azimuthal alignment by the two localization laws of the three directions of north, west and up, as well as east, north and up.
In the software design the gyro's drift measure and the process of calibration is added. The Kalman filtering technique is used in the horizontal initial alignment and the azimuth initial alignment.
