Upper bounds on carrier-phase coherence

The vacuum-structure question motivates DSLV-ZPDI. The paper reports two upper bounds. A null is the expected result.

H_S · Chain S

Sky gradient

Between-node double difference of between-satellite single differences. Blind to isotropic site phase. The shared IGS clock residual cancels. A null here does not constrain H_C.

H_C · Chain C

Correlated site-common differential

Same-satellite inter-node difference. A phase identical at every antenna cancels and is unobservable. The bound is the per-baseline maximum, or it is not quoted.

The handset keeps the book

Vanadium can install this as a standalone window. No Play Services. No account. The campaign book stays in on-device storage. Location, if you grant it, fills a site fix you can read before it is saved. It is not uploaded.

The SDR, the GPSDO, and the prompt correlator stay on the DSLV-ZPDI nodes. This app does not synthesize IQ, residuals, or a detection.
