With a simple firmware upgrade, you can benefit from enhanced accuracy using the latest WMM (World Magnetic Model), even on the first generations of our Ellipse sensors.
What is the World Magnetic Model?
The World Magnetic Model (WMM) is a mathematical representation of the Earth’s magnetic field. It enables navigation systems to adjust for magnetic variations, ensuring precise heading and positioning. The model is updated every five years to account for Earth’s magnetic field changes, with the latest release made in December 2024.
Why is it important for Ellipse series?
Ellipse series features built-in three axis magnetometers to measure the Earth’s magnetic field. Since the magnetic field varies by location and changes over time, the latest WMM ensures that the magnetometer readings are corrected for these variations. This integration enhances the precision and reliability of navigation systems that depend on magnetometer data.
