high res geomagnetic intelligence for navigation
The Earth’s magnetic field is generated in the core and strongly modified by the crust and upper mantle. These regional magnetic features matter for navigation. Modern autonomous and hybrid navigation systems continue to rely on magnetic heading information, particularly where GNSS is unavailable, degraded, or denied.
machine-readable compass corrections
Accurate heading correction requires more than a global average magnetic model. The World Magnetic Model High Resolution 2025 (WMM-HR 2025) provides much finer spatial resolution at the (approx. 300 km vs 3300 km at the equator) and explicitly models crustal magnetic components, capturing regional anomalies that materially affect compass heading.
This makes WMM-HR especially important for autonomous vehicles, surveying platforms, aviation, maritime systems, and land navigation operating in GPS-deprived or GNSS-challenged environments. Our web API exposes WMM-HR declination, inclination, and field intensity with time and altitude support, suitable for real-time use or cached lookup tables for offline operation.
- Approx. 10 times higher spatial resolution than WMM2025 at the equator
- Explicit crustal magnetic field modelling for regional accuracy
- Improved performance over continents and complex terrain
