Popis: In order to decrease the temperature error of MEMS gyroscopes, a mitigation method based on gyroscope array was proposed. Angular rate of MEMS gyroscope fluctuates dramatically with the change of gyro temperature when gyroscope starts up. The temperature characteristic error of MEMS gyroscope has become one of the major errors in the practical application. A mitigation method for temperature error was presented based on MEMS gyroscope array utilizing high correlation of temperature errors in the same batch of MEMS gyroscopes. This method was designed to improve environmental adaptability and shorten the startup time of MEMS based inertial measurement unit. Experimental results showed that the method was feasible and effective.
