| Abstract: | In view of the problem of the drifts of the zero point of gyro as a result of D/A conversion cir- cuit's variation timely using in the gyro's rebalance loop,an method of amending the D/A's variation was presented.The calculation and test results show that the technique can control the D/A's variation effect.The precision of the inertia system can be improved. |
