UNIVERSITY OF CALGARY Performance Evaluation of Multiple Reference Station GPS RTK for a Medium Scale Network
Bibliographic record
Abstract
ii Carrier phase-based single reference station (SRS) positioning is capable of providing decimetre to centimetre-level accuracy for static and kinematic positioning under normal atmospheric conditions where the inter-antenna distance is relatively short, namely below ten to twenty kilometres. However, under highly localized atmospheric activity, and/or with a longer inter-antenna distance, the residual differential error increases and the accuracy degrades. Carrier phase integer ambiguity resolution may be impossible. Multiple reference station (MRS) approaches uses a network of GPS reference stations to predict the differential errors over a geographic region. The University of Calgary standard MRS approach uses a conditional least-squares adjustment technique. During the past few years, an MRS tightly-coupled approach, which used all available observables obtained at rover and network reference stations in one filter, was also developed; the objective of this approach was solely to estimate states such as ambiguities, rover position and ionospheric error, if specified.

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.
