Outdoor yard GPS vs indoor hall track
The trailer is on site according to the yard board. The kit still is not at the line. Outdoor and indoor place were never one story.
Where outdoor location stops helping the hall
GPS and similar outdoor radios answer campus and yard questions: which trailer is in which lot, which tug is on the ring road, whether a vehicle approached the dock face from outside. Inside a steel-roofed hall those signals drop or drift. Aisle search, free forklift claim, and buffer dwell need an indoor RTLS stream, typically at medium precision around 1–3 m (3–10 ft).
Buying only yard GPS does not track internal logistics. Buying only indoor tags does not explain why a trailer sat two hours before the load entered the hall. Plants that run both scopes need a clear handoff at the dock, not one slide that pretends one radio covers both jobs. Treating the whole campus as one coarse zone hides which wait actually burned the shift.
What the dock handoff must name
Handoff is the moment outdoor presence becomes an indoor logistics object. A trailer arrives. A cage crosses the dock. An indoor mover takes the load. Yard management owns gates, appointments, and trailer states. Hall logistics tracking owns movers and loads after they are inside. twinzo's indoor hall can show the internal side. The yard system still owns the perimeter story unless the plant deliberately bridges identities at the door.
When both streams exist, stored places still matter. Outdoor dwell at the gate and indoor dwell in the buffer are different waits. Keeping them in a spatially oriented dataset with clear area names lets later correlation and causality analytics ask which yard delays keep preceding indoor starves, without mixing the two clocks. Accuracy language for the indoor half is under zone presence vs medium-precision logistics track. Outdoor GPS as an RTLS peer is under GPS for RTLS.
A typical dock gap between two true screens
At 11:10 the yard board shows the trailer docked. At 11:55 the line still waits. Indoor tracking never saw the load because the cage sat on the dock apron outside coverage, or because identity never crossed from trailer ID to cage ID. Ops argues with the carrier. Logistics argues with production. The missing fact is the handoff rule: when does outdoor presence become an indoor tagged object, and who owns that moment. Object choice inside the hall remains under tagging the mover vs tagging the material.
Do not fund a hall FGS or AOS pilot with yard language, or a YMS project with aisle-find promises. Different owners, different proofs. Indoor empty travel and free-truck claim still need the hall stream under loaded vs empty travel you can prove and where the free forklift actually is.
How teams keep the scopes honest
1. Write separate success tests for yard arrival and hall find - One radio rarely passes both.
2. Name the dock as the handoff, not the whole campus as one zone - Blunt geometry hides the wait.
3. Keep YMS purchase language off the indoor FGS or AOS pilot - Different owners, different proofs.
4. Bridge identity only for loads that must stay continuous across the door - Not every trailer needs an indoor tag story.
Indoor logistics tracking sits under internal logistics optimization and features. Production waits inside the hall are under production monitoring. Pricing is under pricing.
