| Abstract: | A new data acquisition system circuit used for gyroscope signal from strapdown navigation system was designed,which adopt A/D automatic gain control circuit.The system deter hardware mines magnifying times according to pre-sampling, which resolves the problems due to wide dynamic range.This paper presents the hardware and the selection and application of elements.The software gives the flow chart of data acquisition. Finally, the real test results are given,which indicate that this data acquisition system has advantages of high accuracy,real-time performance, and wide dynamic range.The research work has great potential applications. |
