Abstract


Aeromagnetic survey on the attitude angle vectors required accuracy is very high, in order to improve posture angular accuracy , we design a set of IPAS20 system analog channel data acquisition and processing system . This paper introduces the basic principles IPAS20 system working and working process , through the acquisition of part of the PXI system acquisition IPAS20 system analog channel data . In order to study IPAS20 system NUS5 various models of IMU gyro drift and designed two sets of experiments were laboratory experiments and outdoor experiments . Each experiment for 24 hours , respectively , by two sets of experiments to find the law gyro drift , and observing whether the external environment impact gyroscope . After 48 hours of experimental lots of experimental data with the data characteristics, the data-processing tool MATLAB to process the data . Processing results finally obtained , and the results for the data analysis, two groups of experimental conditions gyro drift , temperature drift of the gyro rate of such conclusions.
