How to read this
The chart traces timing (or position) error over the run. While GNSS is available both solutions track truth; when it cuts out, each coasts on its own sensors. The quieter sensor stays inside the spec threshold longer — that coast time is the holdover. The summary reports holdover, error percentiles, and availability for the quantum and classical options side by side.
Clock stability (overlapping Allan deviation)
Lower is better. The Allan deviation σy(τ) shows how a clock's fractional-frequency stability changes with averaging time τ — a quieter clock coasts longer through a GNSS outage.
