Distributed Fibre Sensing
DAS, DTS and compatible DSS observe spatial phenomena along the corridor.
01 · Why this observatory
Continuous + selective observation.
IDRCIN combines distributed fibre sensing, autonomous specialised point sensing, UAV / remote sensing and temporal reconstruction. Different scientific questions require different capture modes. Research Question First remains the governing rule.
Autonomous Point Sensing
A specialised local probe is considered only when fibre cannot answer the question adequately.
UAV / Remote Sensing
LiDAR, RGB and research-defined thermal surveys provide terrain and canopy geometry.
Temporal Reconstruction
Chainage, XYZ, instrument state and time align inside the proposed Temporal Digital Twin.
Fibre-First scientific decision rule
Research question
Can fibre adequately measure it?
YESUse fibreDistributed or endpoint, subject to compatibility.
NOIs a physical point probe scientifically necessary?NO: do not deploy. YES: use one autonomous scientific pod.
02 · Approved architecture
Fibre-first, with sparse research-defined instruments.
The approved physical baseline remains one ultra-light canopy cable containing approximately 5-6 optical fibres. It has no intermediate electronic fibre nodes, no intermediate DAQ and no powered repeaters.

FIBRE CORRIDOR INFRASTRUCTURE ≠ RESEARCH-DEFINED AUTONOMOUS SCIENTIFIC INSTRUMENT
A LoRa pod is an independent, retrievable research instrument. It is not an intermediate fibre node and does not support or repeat the fibre signal.
No mid-corridor fibre podsZero new terrestrial gateways inside protected forestSatellite / NTN not yet validated
Existing authorised receiver
Direct low-duty-cycle LoRa communication may be evaluated to an existing authorised receiver or research station where RF conditions, link budget, spectrum approval and field validation permit.
Direct satellite / NTN-compatible path
A future direct path may be considered where technically and commercially feasible. Canopy attenuation, terrain shadowing, service availability, regulatory approval and field validation remain unresolved.

03 · Deployment sets
Set A / B / C remain deployment modes.
Each set may use one or more sensing modes only where scientifically appropriate: FD = Fibre Distributed, FE = Fibre Endpoint, AP = Autonomous Point Sensor, HY = Hybrid, RS = Remote Sensing.
Set A · Canopy Observation
FDRSAP only if justified
Primarily distributed canopy fibre and repeat UAV context. A point probe is exceptional, not assumed.
Set B · Autonomous Canopy-to-Ground
FDFEAPHY
The canopy cable remains primary. Autonomous endpoint/drop and retrieval remain validation targets.
Set C · Human-Assisted Precision Endpoint
FDFEAPHY
Researcher-assisted placement, calibration and retrieval for precision probes at selected endpoints.
04 · Workflow
Question, plan, observe, validate, retrieve.
Point-sensor selection is a formal decision inside the existing fibre workflow, not a parallel wireless deployment programme.
05 · Sensing functions
Three acquisition classes, one scientific architecture.
Distributed fibre, fibre endpoint instrumentation and autonomous specialised point sensing are complementary. They have different spatial, power, payload and maintenance models.
DAS · DTS · DSS
Best for spatial phenomena along a compatible fibre corridor: thermal behaviour, vibration, strain-related response and validated event candidates.
Terminal instrumentation
Precision measurements at an approved terminal or optical endpoint. Power and interface depend on the selected instrument; arbitrary electronics do not run directly over passive fibre.
LoRa scientific pod
One specialised probe at one selected point. LoRa carries small summaries, events and health telemetry, not continuous high-bandwidth raw data.
| Attribute | Fibre Distributed | Fibre Endpoint | Autonomous Point Pod |
|---|---|---|---|
| Spatial model | Continuous corridor | Terminal point | Selected point |
| Power at measurement point | Typically passive fibre | Depends on instrument | Battery |
| Communication | Fibre | Fibre / endpoint system | Low-duty-cycle LoRa |
| Payload | High / continuous at interrogator | Instrument dependent | Small scientific payload |
| Maintenance | Low along passive fibre | Endpoint dependent | Selective and condition-based |
| Best use | Spatial phenomena | Precision endpoint | Specialised physical probe |

Lightweight, identifiable, retrievable, relocatable and reusable where practical. Large permanent multi-sensor stations require explicit research justification.
Ultra-low-duty-cycle lifecycle
Deep Sleep→Wake→Sample→Local Validate→Store→Transmit Decision→Sleep
Normal operation sends periodic summaries. An event may trigger a compact payload. Target battery life is subject to sampling profile, sensor load, RF conditions and field validation.
Connectivity loss must not equal data loss:SENSE↓STORE LOCALLY↓RETRY LATER↓RECOVER DURING RETRIEVAL
Timestamped storage, sequence numbers, retry limits, duplicate detection, last-known-good state, watchdog, safe reboot, battery/sensor/communication state and calibration metadata are conceptual requirements.
06 · Observation corridor
Chainage + XYZ + selected pod locations.
Every autonomous pod must be registered in the same geospatial system as the fibre route so point measurements can be related to distributed events, terrain, canopy and time.
Fibre chainageXYZ coordinatesTerrainCanopyPod locationTime
07 · Temporal terrain / canopy reconstruction
The Digital Twin also tracks instruments.
DSM, DTM and CHM remain derived spatial products. A pod is a time-aware asset overlay, not evidence that a live operational Digital Twin already exists.
DSM
Digital Surface Model from canopy and surface returns.
DTM
Derived terrain model from filtered ground returns where available.
CHM
Derived canopy height model, commonly DSM minus DTM.

09 · 6-fibre baseline
1 cable × 6 optical fibres + sparse out-of-band pods.
LoRa is not assigned to a fibre channel. The six-fibre baseline remains unchanged; autonomous pods are independent scientific instruments.
F1 baseline
DTS along the corridor. Interpretation requires compatible fibre, optical budget, calibration and environmental context.

Condition-based maintenance
Dashboard states: ONLINE, NO RECENT DATA, LOW BATTERY, SENSOR FAULT, COMMUNICATION DEGRADED, CALIBRATION DUE, RETRIEVAL DUE, RETRIEVED and LOST / UNRECOVERED.
No zero-maintenance claim is made.
Ecological accounting
Benefits: sparse deployment, no new terrestrial gateway network, reduced repeated entry, reusable/retrievable instruments and low-duty-cycle operation.
Costs: batteries, electronics, enclosure material, possible lost pod, retrieval activity and wildlife interaction.
Satellite / NTN: NOT YET VALIDATED
Any future use is conditional on canopy attenuation, terrain shadowing, link-budget analysis, commercial service availability, regulatory approval and field validation. Coverage is not guaranteed.
