Range-Extended Post-Processing Kinematic (PPK) in a Marine Environment
Bibliographic record
Abstract
We have been investigating on the extension in range of baselines used in support to marine applications. Our focus has been with PPK (post-processing kinematic) following the Remondi’s lemma: it is better to have a reliable float ambiguity resolution rather than a wrongly fixed ambiguity”. We have focused our attention on the residual effect due to differential troposphere. Our investigation makes use of data sets collected under the scope of the Princess of Acadia Project. In this paper, we focus on a storm know as the 2004 Halifax weather bomb. Zenith tropospheric delays have been compared for that time period. It is shown that using Numerical Weather Prediction (NWP) GEM model provides a better agreement with the zenith delay as provided by the IGS tropospheric product for station IGS UNB1. We have developed a program, the UNB NWP Ray-tracing software, intended to compute zenith and slant path delays from NWP data sets. This paper shows the state of the art in our efforts towards using NWP for positioning.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
