Modeling of regional magnetic field applying spherical functions: practical aspect

Геофизический журнал, 2019
Modeling of geomagnetic field and creation of geomagnetic maps is one of the main directions of geomagnetic studies. For constructing global model the global spherical Lejeandre functions are used in most cases, though for constructing regional magnetic ...

An Optimized Two-Step Magnetic Correction Strategy by Means of a Lagrange Multiplier Estimator with an Ellipsoid Constraint

Sensors, 2018
The geomagnetic field is as fundamental a constituent of passive navigation as Earth’s gravity. In cases where no other external attitude reference is available, for the direct heading angle estimation by a typical magnetic compass, a two-step ...

Comparison of global geomagnetic field models and evaluation using marine datasets in the north-eastern Atlantic Ocean and western Mediterranean Sea

Earth, Planets and Space, 2018
Many models describing the Earth’s magnetic field exist and are maintained by international research organizations. However, no clear general overview of the cross-compared quality of these models is available. An evaluation of the internal component and
