Abstract
The authors describe the successful modification of a ring laser gyro (RLG) strapdown inertial reference unit into a strapdown inertial survey system (SISS) for geodetic positioning. The system, a Litton LTN-90-100, has been modified into a land-vehicle mode inertial survey system by developing specialized software and error control techniques. The software package integrates the raw body rate and acceleration data from the LTN-90-100 into velocity and coordinates of the system. The error states of the SISS are estimated by a Kalman filter-smoother using regular zero velocity measurements and occasional control coordinates as updates. The system was tested on an L-shaped baseline near Calgary and results show that a positioning accuracy of better than 1 m (1 sigma ) is achievable. >

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 it
