Abstract
Based on the accelerometer signal acquisition requirement of the high precision strapdown inertial naviga-tion system, this thesis proposes a new design scheme, which has the advantages of high precision, low power consumption and miniaturization. Meanwhile,digital compensation method is used to improve the precision of zero bias and scale factor in full temperature range by one order. Test data shows that the temperature coefficient of the circuit scale factor is below 0.5 ppm/℃,zero bias is below 10 μg in -55 ℃～+85 ℃ temperature range,and the scale factor repeatability of a year is below 10 ppm,power consumption is 1.8 W. The test results indicate that the circuit scheme meets the requirement of SINS.关键词
