Inertial sensor is important for navigation applications.In this paper,the integrated inertial sensor of ADI's ADIS16355 was studied experimentally with a three-axis turntable SGT320E.After a brief introduction of its application in navigation and basic IO operations about data reading and processing,procedures were presented to test ADIS16355 in terms of sensor bias,scale factor,scale factor linearity and long-term stability performances,which led to establishing of its output model.The experiment data with the three-axis turntable was analyzed using Matlab and it was shown that the ADIS16355 XYZ axis static gyro drift and scale factors were in agreement with its datasheet.
