磁通门经纬仪分量测量法在机场磁偏角测量中的应用
Application of fluxgate theodolite component method in airport magnetic declination measurement
摘要
Abstract
This paper discusses a new method for measuring airport magnetic declination using the DI magnetometer,the component method,which calculates the magnetic declination using the horizontal components(X,Y)of the geomagnetic field measured by the DI magnetometer,analyzes the main factors that affect the measurement accuracy of magnetic declination,and explains in detail the calculation process of the DI magnetometer for measuring the horizontal component of the geomagnetic field and the magnetic declination.Practice has shown that the observation and calculation methods to measure airport magnetic declination using the component method are reasonable.This measurement method is consistent with the measurement results obtained by the conventional near zero method,and its measurement accuracy meets the requirements of relevant measurement specifications.In addition,since there is no need to track the zero position of the horizontal magnetic field during the measurement process of the component method,using the component method to measure geomagnetic declination is more convenient and efficient,and is more suitable for field measurement occasions such as airports and docks.关键词
