A quality score, a coordinate solution and agreement between two solutions answer different questions. We keep those boundaries visible.
01 / A reproducible quality check
69.6/100
quality score
The bundled BJFS sample scored 69.6 in Fast Mode: all epochs were present, but no multipath measurements were recorded, earning 0/30 for that component. Its sampling interval is 30 seconds. Open the bundled example in the free quality check for the latest computed result.
Precise-positioning cross-check runs two independent scientific-grade geodetic engines on the same uploaded observation set, then compares matched station coordinates. It is separate from the Fast Mode quality check. Both sides must return usable results for a two-sided comparison; an absent solution is not agreement.
The approved cross-check agreement threshold is 20 mm in three dimensions per uploaded station. The run is within threshold only when every uploaded station has a two-sided comparison at or below that difference. Added reference stations are informative, not the deciding population. The threshold determines the agreement conclusion, not permission to publish a solution.
The initial approval used 14 samples, below the planned 20-sample gate: eight uploaded stations in live runs and six acceptance pairings. The owner accepted that limited evidence. It is not independent certification or a promise that future uploads will agree.
04 / Agreement is not ground truth
Two solutions can share errors in input data, station metadata or reference-frame assumptions. Agreement does not establish external accuracy, legal suitability or fitness for a deliverable. Check frame, epoch, antenna setup and independent control. We publish failure rates and charging boundaries so you can decide whether a run is appropriate.
