Abstract
Safran Electronics & Defense’s hemispherical resonator gyroscope, the HRG Crystal <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">™</sup> , has widely proven its ability to fulfill performances requirements usually reached by optical technologies (RLG and FOG), with the best C-SWaP <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> characteristics and much higher reliability (cf. DARPA latest study [5]).Based on HRG Crystal <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">™</sup> technology, Safran Electronics & Defense has developed a new type of inertial core called HRG Crystal <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">™</sup> DUAL CORE, able to reach higher performances similar to the ones achieved by ESG technology.Indeed, thanks to the unrivalled C-SWaP of HRG Crystal <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">™</sup> for navigation grade gyro, the integration of multi sensors cores in a single cluster-core, made of 6 HRG Crystal <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">™</sup> gyroscopes (instead of 3 for “standard” cores), and accelerometers, becomes possible.The DUAL CORE principle, patented by Safran Electronics & Defense, relies on resonator gyroscopes’ intrinsic characteristic: its self calibration capability. Thus, in a DUAL CORE, while 3 gyros are navigating, the 3 others are self calibrating, strongly increasing the inertial system’s accuracy.HRG Crystal <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">™</sup> DUAL CORE allows Safran Electronics & Defense to address the most demanding applications with breakthrough products. For instance, in the naval market, Safran has launched at Euronaval 2018 the Black-Onyx <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">™</sup> DUAL CORE, an INS for submarines that addresses the market with unreached performances: better than 0.5 NM/120h.There is no doubt that, in the near future, other defense sectors, like land and aeronautics, will be addressed with HRG Crystal <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">™</sup> DUAL CORE inertial systems, as the need of extended performances, with better C-SWaP, becomes more and more significant each day.

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
