Fiber optic gyroscope (FOG) is a rate gyro suitable for table test at low angular rate. Based on the parameter of table's encoder, the data updating rate requirements of FOG at different angular rates and the influence of FOG's bias stability on measurement were analyzed. The table was tested at angular rate of 1°/s by FOG. The frequency spectrum of the FOG output was analyzed and compared with oscilloscope measurement. The result showed the measurement of FOG was correct. The table was tested at angular rates between 0.05°/s and 1°/s by FOG. The test results show that FOG can be used for table test, and the angular rate fluctuation of table test at low angular rate can be measured by FOG. And the minimum angular rate of the test was given.
