The Accurate Measurement of Tilt Direction within Small Angles of Tilt
Original language description
This work focuses on the measurement of tilt and the tilt direction specifically in small angles. Particularly problematic is the measurement of the tilt direction within tilt angles up to 10°. In such small angles the direction is excessively impacted by noise and it is impossible to measure it precisely. However, in application where the accurate information about it is needed one accelerometer might not be sufficient. The method proposed in this paper introduces two accelerometers shifted from each other by 45° counterclockwise in the x and z axes at the same time. The axes of the shifted accelerometer are not affected by the noise as considerably and the measurement of tilt direction is more accurate. This claim is supported with mathematically derived equations and measured data. The proposed optimisation allows to measure tilt from vertical line and its direction relatively easily with enlarged precision.
