Abstract
This paper will briefly introduce the main methods to reduce or eliminate various errors at present. The main body of the paper is to introduce and discuss the correction methods of satellite ephemeris error and satellite clock difference, ionospheric delay, multipath effect, antenna phase center eccentricity correction, relativistic effect, tide correction and tropospheric path delay error which affect the accuracy of satellite navigation and positioning. In addition to the non-dispertic medium, the degree of change of tropospheric medium with time is relatively drastic, and it is difficult to use a simple and unified mathematical model to determine, especially in the long relative positioning of the baseline, the tropospheric delay between the two stations often shows a weak spatial correlation. Therefore, it is of great significance to establish a real-time tropospheric delay model in a certain region to improve the accuracy of satellite navigation.

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
