Testing the Coarse Alignment Algorithm Using Rotation Platform

The paper deals with testing the coarse alignment algorithm for the inertial measurement unit ADIS16405 using a rotation platform. The ADIS16405 is the new six-degree of freedom inertial measurement unit which is being produced by Analog Devices. The main goal of the paper is to describe the determination of the initial attitude of the inertial measurement unit with respect to the navigation frame as a referenced frame and to depict appropriate tests using a rotation platform. In this work the attitude is represented by the Euler angles (the roll, pitch and yaw angles). The tests were conducted using the INS/GNSS development kit which had been mounted on the rotation platform. The overall factual results are illustrated and correctness of the algorithm was definitely confirmed.
