Abstract

fetched live from OpenAlex

Purpose The purpose of this work is to obtain an overbounded broadcast sigma from actual (non-Gaussian) correction error distribution under the stringent navigation integrity requirements for aircraft precision approach and landing. Design/methodology/approach Approach is statistically to overbound satellite pseudorange correction error distribution with the use of numerical solution of Fisher- Z transformation. Inflation factors for overbounding broadcast sigma are extracted from Fisher- Z transformation based on measured correlation and counted independent identically distributed (iid) sample sizes of true empirical data. Findings New overbounded broadcast sigma values for eight long-pass satellites were obtained based on measured actual empirical data and ensured integrity risk at 10 −8 probability level. Proposed methodology successfully overbounds ground reflection multipath-type systematic and temporal errors sources. Originality/value This paper introduced a new method of accounting for ground reflection multipath for local area augmentation system/ground-based augmentation system navigation integrity. The method is also applicable to statistically overbound any other serially correlated temporal variation in measured data if both correlation values and finite iid sample sizes are known.

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.
