Abstract

The geomagnetic field is generated inside its molten iron core as a result of a mixture of the electrical forces within the core, daily Earth's rotation, and its thermal movement. The purpose of the study is to build the model of the near equatorial magnetic field, studying the effect of South Atlantic Anomaly on the near equatorial satellites and analyzing the characterization of the geomagnetic field. The building of the model is important since it can provide a better result in a small area compare to a large area. In this research, 6 stations located near the equatorial region were selected. The stations chosen can be used in designing the model using spherical cap harmonic analysis. The result for this research is still preliminary stage. The model constructed will be tested, verified and validated. The well-verified model will be capable to predict the characteristic of the geomagnetic field and can be used to study the effect of South Atlantic anomaly on the near equatorial satellites.

近赤道磁场模式与南大西洋异常的初步研究

地磁场是在它熔融的铁芯内部产生的，这是地核内部的电力、地球的每日自转和热运动混合作用的结果。本研究的目的是建立近赤道磁场模型，研究南大西洋异常对近赤道卫星的影响，分析地磁场的特征。模型的构建很重要，因为它可以在小区域提供比在大区域更好的结果。本研究选取了靠近赤道地区的6个台站。选取的台站可用于球帽谐波分析模型的设计。这项研究的结果还处于初步阶段。构建的模型将被测试、验证和验证。经过验证的模型将能够预测地磁场的特征，并可用于研究南大西洋异常对近赤道卫星的影响。
