The calibration of Micro-Electro-Mechanical System (MEMS) gyroscopes is important for the application in which an angle is measured. The equipment for the calibration of this sensor is not always available. In this case, the method of simulated identification can be used. Some of the conditions are: using different tracks with saving angular velocity measurements, knowledge of influencing variables with their monitoring, and knowledge of the initial and final states of the angle. Based on this information, an algorithm is designed for the correction of influencing parameters by computer equipment. In our case, offsets, gains, and cross coupling coefficients are calculated for each axis of a sensor ADIS16405BLMZ. The result is an error of up to 0.5°/min of movement. To obtain high accuracy results, it is necessary to reach the conditions which are described in this contribution.
