Post-Event Damage Verification

Using satellite optical, SAR and multispectral imagery to independently verify the extent and severity of damage after disasters, enabling fast, fraud-resistant insurance settlements.

When a catastrophe strikes — flood, earthquake, wildfire, hurricane — insurers face a brutal trilemma: settle fast and risk fraud, dispatch adjusters and face weeks of delay, or dispute claims and face political and reputational blowback. Ground access is often impossible in the immediate aftermath, and claimant-provided photos are trivially fabricated. Satellite imagery acquired within hours of an event delivers an authoritative, timestamped, spatially precise record that no ground-level account can contradict or manufacture.

A sovereign post-event verification constellation combines SAR for all-weather, day-night imaging with high-resolution optical (sub-50cm) for visual confirmation and multispectral change-detection for crop, vegetation and structural damage. Comparing pre- and post-event image stacks against a national cadastral database identifies affected parcels to the individual building or field level. ML-driven damage classifiers — trained on local building typologies, land-use patterns and historical disaster signatures — produce a damage-grade map within 6 to 12 hours of image acquisition, long before any adjuster reaches the scene.

For a national government that underwrites sovereign disaster insurance, reinsurance pools or agricultural guarantee schemes, controlling this pipeline eliminates dependence on foreign commercial imagery vendors who can deprioritise tasking, impose embargo-equivalent export controls, or simply be overwhelmed by concurrent global demand during a major event. The operational outcome is a legally defensible, auditable evidence base that cuts average claims-cycle time from weeks to days, suppresses organised fraud rings that exploit post-disaster chaos, and gives treasury and reinsurance counterparties hard data rather than contested field reports.

What matters

Post-disaster commercial imagery demand spikes globally at exactly the moment a nation needs priority tasking — sovereign assets guarantee it.
SAR penetrates cloud cover and smoke, the two conditions that most reliably accompany floods and wildfires respectively, when optical-only solutions go blind.
Building-level damage grading from satellite change-detection has been validated to better than 80% agreement with ground-truth surveys in peer-reviewed post-earthquake studies.
A foreign vendor supplying damage-verification imagery to both the insurer and the sovereign reinsurer creates an unresolvable conflict of interest over which party controls the evidentiary record.

Sovereignty score: 8/10 — A nation that cannot independently verify disaster damage cedes the evidentiary standard for its own insurance settlements, reinsurance negotiations and disaster-loss accounting to foreign commercial vendors.

Commercial imagery vendors operate under their home state's export and national-security controls; a major geopolitical event can legally restrict tasking over precisely the territory a sovereign insurer needs to assess.
National reinsurance and sovereign catastrophe bond structures require auditable, independently produced loss data — data sourced exclusively from a single commercial provider is legally contestable and actuarially suspect.
Organised post-disaster insurance fraud exploits the delay between event and adjuster access; sovereign rapid-revisit imagery closes that window before fraudulent claims can be staged or documentation fabricated.
Domestic building registries, cadastral databases and land-tenure records needed to link satellite damage maps to individual policy holders are sovereign data assets that cannot legally or practically be shared with a foreign commercial operator processing imagery offshore.

Reference architecture

Payload: Dual-payload per satellite: (1) pushbroom optical at 40cm GSD, 12km swath, RGB + NIR; (2) X-band SAR in stripmap mode at 3m resolution, 30km swath, with 1m spotlight mode on tasking. Optical supports visual damage grading and change-detection; SAR provides all-weather flood-extent and structural-collapse mapping.
Bus class: ESPA-class microsat, 150–200kg, 600W payload power, deployable solar array, S-band TT&C, X-band downlink at 300 Mbps. Dual-payload integration requires a stable 3-axis ADCS with sub-30 arcsecond pointing for optical mode.
Orbit: Sun-synchronous LEO at 520–560km, 18-satellite walker constellation (two orbital planes, 9 satellites each), achieving sub-4-hour revisit over any point in the national territory and adjacent EEZ; nominal repeat cycle 12 hours for same-illumination optical comparison.
Ground segment: 4-station national network (X-band science downlink, S-band TT&C) co-located with national meteorological and civil-protection facilities; encrypted inter-site links; SatNOGS-compatible UHF/VHF housekeeping backup. Ground stations sited to ensure at least two contacts per orbit.
