A study on the design of the A-D converter for analog rebalance loop in INS

관성측정장치의 아날로그 재평형 루프에 따르는 A-D 변환기의 설계에 관한 연구

This paper describes the hardware of analog-to-digital converter to process the rate output of analog servo loop for the gyro rebalance of INS. The analog-to-digital converter is designed by voltage-to-frequency method which is generally used in INS, and this scheme fits well into the strapdown INS that requires the wide dynamic range and linearity. The output of the designed voltage to frequency converter is tested by computer through the counter and all the factors which affect the performance are considered.
