Manoeuvre Recognition Using A Low-Cost Standalone MEMS-IMU System
Bibliographic record
Abstract
This paper describes the use of a low-cost standalone MEMS-IMU (micro-electromechanical system - inertial measurement unit) sensor system developed by the National Research Council Canada (NRC) for manoeuvre recognition in helicopters. The system records accelerations, angular rotation rates, magnetic flux, altitude, location and velocity through its IMU and GPS. The MEMS-IMU system was flown on the Bell 206 helicopter operated by the NRC Flight Research Laboratory in two unscripted flight tests. Comparison of the system's measurements with those of the helicopter's inertial navigation system (INS) shows very good agreement, demonstrating that the system functions well in the intended environment and its measurements provide accurate and meaningful data. Data visualization of the flight test data mapped into a 3D virtual reality representation is presented to provide insight into the structure of the flight data. Manoeuvre recognition based on the sensor system's measurements was attempted using a data-driven classifier model. Even with different subsets of the MEMS-IMU measurements, the classifier results show that the parameters recorded by the system are sufficient for accurate manoeuvre classification.

Full frame distilled prediction
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
