Abstract
Satellite transmission of orbit and clock corrections is critical for real-time positioning, navigation and timing (PNT), geoscience applications, safety and liability critical services based on Global Navigation Satellite Systems (GNSS) precise positioning. In response to such a demand, Galileo has established a High Accuracy Service (HAS) of almost global coverage for GPS and Galileo. We validate the quality of HAS corrections and investigate service performance in a variety of applications. Decimeter-level accuracy of HAS corrections leads to static and kinematic positioning with precision of a few centimeters and sub-decimeter, respectively, and timing precision of a single nanosecond. Other GNSS-derived products meet the requirements of real-time GNSS meteorology and allow for monitoring coseismic vibrations. Although other Internet correction streams offer superior results, HAS provides better performance than nominal and nearly global coverage.

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
