【Abstract】 The cause of FOGs random walk is studied. And the random walk coefficient is analyzed and computed based on Chinese state standards and the Allan variance means respectively. The computation results show that the random walk is a key criteria defining the noise of FOG and reflects the gyros limit performance of the gyro. The Allan variance means demonstrates the advantages of clear physical concept and efficiency in describing the static performance of FOG.更多还原
