Imu Magnetic Interference Calibration Checklist Uk
Imu Magnetic Interference Calibration Checklist Uk is a label-first, evidence-first decision: start with the maker's instructions, then use the checks below before buying, cleaning, measuring or changing a routine.
Indoor IMU yaw goes wrong: a UK maker checklist for magnetic interference and recalibration
This guide keeps the scope narrow: it answers the search question, separates confirmed evidence from assumptions, and avoids treating a product page as proof for claims it does not make.
The MathWorks is used here for: Hard-iron and soft-iron effects shift/stretch magnetometer spheres and require calibration parameters. The VectorNav is used here for: HSI calibration maps distorted ellipsoid back toward a centred sphere; 2D vs 3D cal motion guidance. The Analog Devices EngineerZone is used here for: Practical hard-iron vs soft-iron interference categories for MEMS magnetometers.
Decision Checklist
- Direct answer: yaw drift near steel racks, speakers, and tool chests is usually magnetometer contamination, not a broken gyro alone
- Explain hard-iron vs soft-iron in plain UK workshop language
- Checklist: move away from steel, rotate for cal, re-test heading, decide when a calibration jig helps
- Who should ignore magnetometer: pure tilt/pitch-roll jobs that can run fused without relying on heading
- Link fact-safe accessory boundary: magnetic calibration jig SKU exists for users who need structured cal motion
Evidence Boundaries
- Use the cited source and the site evidence only.
What Not To Assume
- Avoid claiming a specific residual heading accuracy after calibration for the site SKU
- Avoid imply calibration makes the device navigation-grade or aviation-safe
- CTA only for users who already decided they need magnetometer-based heading
Practical Next Step
Use the checklist in order. If the manual, care label, appliance guidance or safety source says no, stop there; if it says yes, test the least risky small area or setup before scaling up.
