Usage of Electrolytic Tilt Sensor for Initial Alignment of Tri-axial Accelerometer

Popis výsledku v původním jazyce

A precise initial alignment in navigation strongly depends on the accuracy of the initial static acceleration measurements and consecutive attitude evaluation. Therefore, the evaluation is affected by accelerometers' imperfection, which is in this case the initial bias. This paper deals with a usage of a dual-axis electrolytic tilt sensor EZ-TILT-2000-008 to improve the initial alignment done by accelerometers, which form a part of inertial measurement unit ADIS16405. There were performed several measurements under various initial conditions with a usage of a precise Rotational-Tilt Platform as a reference. Based on measured data alignment procedure accuracy, null repeatability, and stability of initial null angle were analyzed. The electrolytic tilt sensor can be used to estimate accelerometer's biases and thus it improves the accuracy of initial alignment, computed pitch and roll angles respectively.
