• Hard/Soft Iron Calibration: Algorithms, often 3D, are used to compensate for local magnetic interference (e.g., metal, electronics).
• Tilt Compensation: Integrated 3-axis accelerators (accelerometers) correct for heading errors when the compass is not level, with some systems functional up to
  

  $\pm {80}^{\circ }$
  of tilt.
• Industrial-Grade Reliability: Sensors typically feature operating temperatures of
  

  ${-40}^{\circ }\text{C}$
  to
  

  ${\mathrm{+85}}^{\circ }\text{C}$
  , IP67 waterproofing, and high shock resistance for demanding applications.

• 3D vs. 2D Compensation: While 2D may suffice for level applications, 3D compensation is necessary for high-accuracy, 360-degree, non-level operations.
• Output Data: High-quality modules, such as those from SkyMEMS or Ericco Inertial Technology , offer precise, pre-calibrated heading data.
• Size and Power: Compact, low-power modules are suitable for handheld or drone-based applications, as seen in AliExpress HMC5883L modules or Ericco's compact 2D compass .
