Abstract

fetched live from OpenAlex

Plusieurs services commerciaux du WADGPS (GPS differentiel a couverture etendue) sont fonctionnels a l'heure actuelle et fournissent des services de correction du DGPS (GPS differentiel) a l'echelle continentale en Amerique du Nord et a travers le monde. Etant donne le vaste choix disponible aux usagers du GPS, on a realise une etude sur le rendement de trois importants services de correction, soit le LANDSTAR, l'OMNISTAR et le SATLOC dans un cadre fonctionnel. Les resultats de cette etude font l'objet du present article. L'analyse comprend une evaluation de l'exactitude du positionnement et, en particulier, de la disponibilite des corrections differentielles pour chaque systeme verifie. On a fait l'etude a Calgary, Les resultats demontrent un niveau comparable d'exactitude du positionnement pour les trois services du WADGPS mais avec des disponibilites de positionnement differentes. Les resultats presentes sont utiles pour les usagers du WADGPS en leur permettant de prendre une decision eclairee dans le choix des divers services disponibles.

Full frame distilled prediction

Teacher imitation

Not 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.
