Abstract
ABSTRACT Optically pumped vapour magnetometers have an orientation dependency in measuring the scalar component of the ambient magnetic field which leads to challenges for integration with mobile platforms. Quantifying the three‐dimensional attitude variations (yaw, pitch and roll) of an optically pumped vapour magnetometer, while in‐flight and suspended underneath a rotary unmanned aerial vehicle, aids in the successful development of reliable, high‐resolution unmanned aerial vehicle magnetometry surveys. This study investigates the in‐flight three‐dimensional attitude characteristics of a GEM Systems Inc. GSMP‐35U potassium vapour magnetometer suspended 3 m underneath a Dà‐Jiāng Innovations S900 multi‐rotor unmanned aerial vehicle. A series of unmanned aerial vehicle‐borne attitude surveys quantified the three‐dimensional attitude variations that a simulated magnetometer payload experienced while freely (or semi‐rigidly) suspended underneath the unmanned aerial vehicle in fair weather. Analysis of the compiled yaw, pitch and roll data resulted in the design of a specialized semi‐rigid magnetometer mount, implemented to limit magnetometer rotation about the yaw axis. A subsequent unmanned aerial vehicle‐borne magnetic survey applying this specialized mount resulted in more than 99% of gathered GSMP‐35U magnetic data being within industry standards. Overall, this study validates that maintaining magnetometer attitude variations within quantified limits (±5° yaw, ±10° pitch and roll) during flight can yield reliable, continuous and high‐resolution unmanned aerial vehicle‐borne magnetic measurements.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
