A Multi-Antenna GNSS-Over-Fiber System for High Accuracy Three-Dimensional Baseline Measurement
Bibliographic record
Abstract
A novel multi-antenna global navigation satellite system that uses fibers to transmit signals from multiple remote antennas to a local station with real-time microwave-photonics-based fiber length monitoring is proposed for high accuracy three-dimensional (3D) baseline measurement. In the proposed approach, microwave-photonics-based fiber length monitoring is employed to obtain the delay difference between the different GNSS channels. With the obtained delay difference information, we use the carrier-phase single-difference (SD) algorithm to calculate the 3D baseline, which is able to improve the vertical precision of the 3D baseline measurement as compared with the use of the carrier-phase double-difference (DD) algorithm. Experimental results show that the 3D baseline measurement precision using the SD algorithm is within 2 mm and the vertical positioning precision is improved by over three times compared with the approach using the conventional DD algorithm.

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.
