World Magnetic Model Receives Upgrade

(August 19, 2025)

In addition to the WMM2025, the release includes the first-ever World Magnetic Model High Resolution (WMMHR), which features a spatial resolution of approximately 300 km at the equator, an improvement upon the standard spatial resolution of 3,300 km at the equator. Higher resolution provides greater directional accuracy, making this a significant improvement for users.

In addition to the introduction of the WMMHR, this release comes with some other key changes:

– The WMM predicts an intensification of the South Atlantic Anomaly (SAA) between 2025 and 2030.
– The WMM uncertainty analysis presented in the report has been updated with new data, resulting in a slightly revised error budget.
– The WMM report provides altitude ranges for varying levels of geomagnetic activity.

Magnetic North Pole shift brings updates to World Magnetic Model 2025

(December 25, 2024)

2 versions of the model are:

WMM2025: Standard model with a spatial resolution of 3 300 km (2 050 miles) at the equator.
WMMHR2025: A high-resolution model with an improved spatial resolution of approximately 300 km (186 miles), offering enhanced directional accuracy.

“We’re delighted to join with NOAA and BGS to publish WMM2025 and WMMHR2025, and we encourage users, where possible, to transition to the higher resolution model,” Mike Paniccia, a geodetic Earth scientist and the program manager for the World Magnetic Model (WMM) at the National Geospatial-Intelligence Agency (NGA), stated.

Earth‘s Magnetic North Pole Has Shifted So Much We‘ve Had to Update GPS

(Feb 6, 2019)

Scientists on Monday released an emergency update to the World Magnetic Model, which cellphone GPS systems and military navigators use to orient themselves.

It‘s a minor change for most of us – noticeable only to people who are attempting to navigate very precisely very close to the Arctic.

World Magnetic Model Updated

(December 16, 2014)

Changes in the Earth‘s outer core trigger unpredictable changes in its magnetic field, an invisible force that extends from Earth‘s interior to where it meets a stream of charged particles emanating from the Sun.

US has sent Israel data on aid group locations to try to prevent strikes

The Biden administration has been providing Israel with the location of humanitarian groups in Gaza for weeks to prevent strikes against their facilities. But Israel has continued to hit such sites.

The information included GPS coordinates of a number of medical facilities and information on movements of aid groups in Gaza to the Israeli government for at least a month, according to three people familiar with the communications. All were granted anonymity because they feared speaking publicly would make it more difficult for aid groups to operate in Gaza.

But the north magnetic pole‘s inexorable drift suggests that something strange – and potentially powerful – is taking place deep within Earth

China expands use of BeiDou navigation system in transportation

The BeiDou system began providing services in China in 2000 and surrounding regions in the Asia-Pacific in 2012. When the system is completed in 2020, it will be the fourth largest global satellite navigation system after the U.S. GPS system, Russia‘s GLONASS and the European Union‘s Galileo.

Fake GPS: So könnt ihr einen anderen Standort vortäuschen (Android)

(14.07.16) Mit einem Fake GPS könnt ihr euren Standort schneller und bequemer wechseln, als es mit irgendeinem echten Transportmittel möglich wäre. Und dazu müsst ihr nicht einmal euer Handy „rooten“, da Android alle notwendigen Tools (mit Ausnahme der GPS-Fake-App selbst) bereits ab Werk besitzt.
