The Air Force may ditch GPS for Earth's magnetic field. Here's how that would work, and why the U.S. is long overdue for a new way to navigate.
World Digital Magnetic Anomaly MapSince the Carl-Friedrich Gauss epoch, the Earth's magnetic field has changed dramatically, its dipole moment decreasing by some 10%. This single observation has raised a large number of questions about a future possible polarity transition, and consequently the ...

The Earth’s magnetic field interacts with the Sun’s magnetic field. The interplanetary magnetic field (IMF) is a part of the Sun's magnetic field that is carried into interplanetary space by the solar wind. [http://pluto.space.swri.edu/image/glossary/cme.html]. The Earth’s magnetic fi...
Earth's protective magnetic field is weakening in a region across the South Atlantic. Researchers have been using the European Space Agency's Swarm satellite constellation to monitor changes in Earth's magnetic field. Fortunately, there's no immediate cause for alarm, researchers say, though some...

SUMMARYAnomalies of the Earth's total magnetic field reveal important information about crustal structures. For the first time, a homogenous map of anomalies of the Earth's total magnetic field for the whole of Germany is available. The map is based on 50 shipborne, airborne and ground surveys...
The magnetic anomaly map shows two distinct provinces: in the north the anomaly field trends north-south and decreases towards the east with a gradient of 10 to 20 nT km . In the south the field trends east-west. The magnetic field is generally smooth and most of the magnetic anomalies ...
magnetic field based location discovery system; access an indoor Earth's magnetic field, EMF, map of plurality of buildings, wherein the indoor EMF map represents at least one of magnitude and direction of the Earth's magnetic field affected by the local structures of a corresponding building; ...
Field flips Scientists map and track the overallshape and orientationof the Earth’s magnetic field using local measurements of the field’s orientation and magnitude and,more recently, models. The location of the north magnetic polehas movedby about 600 miles (965 kilometers) since the first...
