Abstract

This paper presents the results of a study of the informativity of the anomalies of the modulus and components of the Earth’s magnetic field in near-Earth space in the altitude range from 300 to 800 km. Magnetic anomalies are calculated according to a three-dimensional component model of the Earth’s magnetic field of the St. Petersburg Branch of the Pushkov Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation. For comparison with the empirical data obtained by the CHAMP and Swarm satellites, the magnetic anomalies and their gradients were calculated according to the component model for altitudes of 400 and 450 km. To reveal the structural features of the lithosphere of magnetoactive zones observed in near-Earth space, deep sections were constructed based on magnetic anomalies, gravity anomalies, and seismological data. The results of the study of magnetic anomalies in near-Earth space are of scientific, practical, and applied importance for solving exploratory geological and geophysical problems and issues of spacecraft navigation.

近地空间地球磁场信息性分析

摘要

本文介绍了对近地空间 300 至 800 公里高度范围内地球磁场模量和分量异常信息性的研究结果。磁异常是根据普希科夫地磁、电离层和无线电波传播研究所圣彼得堡分部地球磁场的三维分量模型计算的。用于与CHAMP和Swarm获得的经验数据进行比较根据400和450公里高度的分量模型计算卫星的磁异常及其梯度。为了揭示近地空间观测到的磁活动带岩石圈的结构特征，根据磁异常、重力异常和地震数据构建了深部剖面。近地空间磁异常研究成果对于解决探索性地质地球物理问题和航天器导航问题具有科学、实用和应用价值。
