Study of the Inclinometer Calibration Method using Geodetic Measurements

The inclinometer is used for small-angle measurement and can be fixed on the radio-communication tower to obtain changes relative to the construction's vertical plane. The real inclination of the tower can be calculated by modellingthe variables obtained from the inclinometer in combination with geodetic measurements. In order to perform assembly error calibration a precise mathematical model based on inclinometer data and total station measurements is proposed. For experimental measurements a dual axis inclinometer and a reference prisms installed on the rigid platform were used. Finally, through simulations of various inclination of the platform, the calibration method is validated and the inclinometer measurement accuracy is evaluated. The preliminary results show the possibility to use this calibration method in order to determine initial position of the inclinometer installed on the tower construction
