IoT projects in consumer or logistics contexts and IoT projects in aerospace manufacturing start from the same basic pattern: tag physical assets, stream location and state events, correlate against a system of record. What changes is the cost of being wrong. In consumer IoT, a bad reading usually just means a dashboard glitch. In aerospace manufacturing, a gap in a serialized component's chain of custody can mean pausing part of a production line while someone manually reconstructs what happened.
Here's roughly how the pieces tend to fit together, based on common patterns in this space.
Identification layer. Parts, tools, and fixtures get a unique identifier, RFID or BLE in most cases, sometimes UWB where sub-meter precision matters more, such as controlled-access zones or high-value tooling. Tags need to survive shop-floor conditions: heat, vibration, machining fluid. Tag failure and misreads are a known operational concern in RFID deployments generally; the specific failure rate depends heavily on tag type, environment, and read frequency, so it's not something to treat as a fixed number without facility-specific data.
Event ingestion. Readers across a facility generate a continuous stream of location and state events. This is a fairly standard time-series ingestion problem: high volume, largely redundant data, with bursts around shift changes. One real architectural decision is how much processing happens at the edge versus centrally. Facilities with intermittent connectivity in certain zones, test chambers or shielded rooms, often lean more heavily on edge buffering than a typical logistics deployment would.
Correlation against production state. This is the part that separates aerospace traceability from generic asset tracking. Every event needs to be checked against what a part or tool is expected to be doing at that stage of production. An event from an unexpected location isn't just a location fact, it's a signal that may need reconciliation against the MES or ERP's expected state. In practice, a large share of the engineering effort in these systems goes into this reconciliation layer rather than the sensor layer itself.
Anomaly detection. With clean event streams tied to expected production state, pattern-matching models can flag parts that have been in one stage much longer than historical norms suggest, tools that haven't returned to an expected location, or access events that don't align with a person's clearance. Much of this is statistical outlier detection and rule-based flagging rather than anything exotic, though it's frequently described in marketing material as "AI."
Traceability export. At the end of the pipeline, the goal is an audit-ready record: every touch a serialized part received, tied to timestamps, operators, and inspection results. This layer tends to matter most to regulators and customers, even though it's the least architecturally interesting part of the system.
This pipeline, identify, locate, correlate, flag, export, generalizes reasonably well across aircraft assembly, defense manufacturing, satellite integration, and avionics production, with the specifics of clean-room or access-control requirements changing by domain.

Curious whether others working in this space have found different tradeoffs on the edge-versus-central processing question, it doesn't seem to get discussed much outside internal vendor documentation.
