Summary
We report empirical outcomes from a proprietary transformation applied to long-baseline GNSS clock comparison in published holdout runs on IGS-class panels: typical RMS reduction around ~45%, strict-window examples up to ~81%, post-process residuals commonly in the 17–22 ns range. Similar movement has been observed across three analysis centers (IGS, CODE, ESA) and multiple years (2023–2025) in those published configurations—not as a guarantee that every window or every participant dataset will match.
This document does not disclose the form, parameters, or implementation of the transformation. It describes only the results and the validation protocol, suitable for blind pilot verification by an independent lab.
Published runs vs pilot: Everything here is from fixed, public IGS-class panels. A pilot engagement applies the same evaluation frame to your agreed inputs under confidentiality. These exhibits show what we observed on the published panels; they are representative of the protocol and domain—not a promise that your panel will match the same magnitude.
Evaluation frame (definitions only)
These definitions specify what is being measured and compared. They do not describe how the transformation is computed.
- What is transformed: an agreed primary comparison or residual series from your submission—we return post-processed outputs and statistics; we do not disclose internal processing.
- Comparator: before = same stream and metric (typically RMS) before our post-process; after = identical metric on what we return.
- Improvement: percent reduction in that statistic; where we cite holdout, no recalibration on the evaluation window.
1. Domain and data
- Domain: Long-baseline GNSS clock comparison (final clock products).
- Data: Multi-baseline, multi-day comparison means (2023–2025).
- Scope: In published runs, effect observed across multiple analysis centers; not one AC only; not identical window-to-window.
2. Main result
Typical held-out RMS reduction ~45% in published panels; strict-window examples up to ~81%; post-process residuals commonly 17–22 ns in those runs.
30-day technical audit (IGS Final, strict holdout)
Single 30-day test window. Transformation calibrated on earlier 2024 data only; applied without recalibration on this window.
| Metric | Uncorrected | Corrected | Improvement |
|---|---|---|---|
| Test window | 2024-250 to 2024-279 | 2024-250 to 2024-279 | — |
| RMS residual | 115.6 ns | 22.1 ns | 80.8% (strict-window) |
Audit note: No recalibration on the 30-day window. Patent pending (priority Feb 2026).
Note: No claim that remainder = 0 or universal applicability. Only observed effect sizes in tested configurations.
3. Validation protocol
| Check | Description | Outcome |
|---|---|---|
| Holdout | Fitted on train; applied on independent test days. | Typical ~45% RMS reduction on test in published panels. |
| Forward-only | Train on earlier days; test on later. | No future-data leakage. |
| Multiple years | 2023–2025. | Comparable improvement. |
| Robustness | Alternative splits; withheld baselines. | Not driven by one subset. |
Demonstration: schematic before/after (illustrative, no method).
