Resilience Investment Planning

Using multi-source satellite data to rank infrastructure assets by exposure, condition and interdependency, so capital investment targets the highest-consequence vulnerabilities first.

Governments routinely underfund infrastructure resilience because the evidence base is weak — engineers lean on ageing ground surveys, and Treasury sees no quantified return on pre-disaster spending. Satellite data closes that gap. Repeated SAR coherence analysis detects millimetre-scale subsidence under roads, dams and pipelines; multispectral imagery tracks vegetation encroachment and surface degradation; thermal infrared reveals heat-loss anomalies in energy networks. Together, these layers produce a continuously refreshed asset-condition register that ground inspection alone can never match in coverage or frequency.

The real analytical leverage comes from combining physical condition scores with exposure modelling. A bridge in moderate structural decline sitting inside a 1-in-50-year flood corridor is a categorically different investment priority from the same bridge in a stable, low-hazard zone. Satellite-derived hazard maps — flood extent histories, landslide susceptibility, coastal erosion rates — feed a network-interdependency model that propagates failure cascades: if this substation fails, which hospitals lose power, which water treatment plants shut down, which arterial routes become impassable? That cascade logic is what converts a list of degraded assets into a defensible capital programme.

The operational outcome is a sovereign, auditable evidence layer that justifies budget allocation to finance ministries, satisfies donor and insurance requirements, and gives planners a baseline against which post-investment improvement can be measured. Nations that rent this analysis from foreign commercial providers face data embargoes during crises, pricing leverage at renewal, and an inability to adapt the methodology to domestic legal or strategic priorities. Owning the pipeline means owning the prioritisation logic — and the political accountability that comes with it.

What matters

Network interdependency modelling — not isolated asset scoring — determines which investments prevent the largest cascade failures.
SAR-derived subsidence detection at 3-5 mm/year precision identifies hidden structural decline years before visible failure.
A sovereign evidence baseline is legally defensible in budget disputes and insurance claims; a rented snapshot is neither.
Hazard exposure layers must reflect domestic legal flood-return periods and national risk tolerances, not vendor defaults.

Sovereignty score: 8/10 — A nation that lets a foreign vendor define its infrastructure risk scores hands the prioritisation of its hospitals, dams and power grids to a counterparty with no constitutional accountability and an extractable data licence.

During a declared emergency or geopolitical tension, a foreign data provider can suspend service or embargo high-resolution imagery of sensitive national infrastructure — exactly when the evidence is most needed.
Resilience investment plans are inputs to national budget legislation and international credit ratings; methodology and data provenance must be auditable under domestic law, not subject to commercial non-disclosure agreements.
Defence and intelligence agencies flag critical infrastructure asset registers as protected information; routing that data through foreign cloud pipelines creates classification and counter-intelligence risks.
Vendor lock-in on prioritisation algorithms means that when pricing is renegotiated at contract renewal, the state has no credible alternative — sovereign capability eliminates that leverage entirely.

Reference architecture

Payload: Dual payload per satellite: C-band SAR (3m stripmap, 80km swath) for InSAR subsidence mapping at 3-5 mm/year sensitivity, plus 5-band multispectral imager (1.5m GSD) for surface condition and land-cover change; optional LWIR thermal channel (60m GSD) on larger bus variants for energy-network anomaly detection
Bus class: 12U to 16U cubesat bus, 14-22 kg, 40-80W payload power; thermal channel variant steps to a ESPA-class microsat at 120 kg and 300W to support the larger LWIR aperture
Orbit: Sun-synchronous LEO at 520-560 km; 18-satellite walker constellation providing 3-day exact-repeat InSAR baseline coverage nationally and sub-daily optical revisit for hazard-event response
Ground segment: Primary X-band downlink at 2 national stations (capital region + geographic diversity site); S-band TT&C; SatNOGS UHF/VHF housekeeping backup; on-premise national data centre with raw archive — no foreign cloud egress of Level-0 SAR data
