For comprehensive magnetic field analysis, a 3-axis fluxgate magnetometer is the ultimate tool. Unlike single-axis sensors, it integrates three orthogonal fluxgate sensors into a single package, allowing for simultaneous measurement of the magnetic field's X, Y, and Z components.

This capability is fundamental for applications like satellite attitude determination, where knowing the exact orientation relative to Earth's magnetic field is crucial. In geophysical surveys, it provides a complete picture of magnetic anomalies, leading to better interpretation of subsurface features.
