Disruption Early Warning

Detecting early signals of supply chain disruption—port congestion, factory shutdowns, flood or conflict damage—by fusing satellite imagery, AIS and RF data before ground reports surface.

Supply chain shocks rarely arrive without warning; they arrive without timely warning to the people who need it most. A port backlog in Rotterdam, a flooded logistics hub in Chennai, or a factory cluster going dark in Zhengzhou each leave visible signatures days or weeks before the disruption cascades into shortages and price spikes. Governments that rely on commercial data brokers or media feeds to learn about these events are always downstream of the traders and hedge funds that already priced the shock in.

A sovereign satellite stack changes the information hierarchy. Optical and SAR microsatellites provide repeatable imagery of the world's 200 most critical logistics nodes—container terminals, rail marshalling yards, bonded warehouses, key border crossings—at sub-24-hour revisit. AIS aggregation flags vessel bunching, anchorage queues and unexpected route deviations. RF survey payloads detect the electromagnetic signature of industrial activity, correlating factory-floor RF emissions with production continuity. Fused through a national ML pipeline, these streams yield ranked disruption probability scores updated every 12 hours.

The operational outcome is a two- to three-week warning horizon that national economic ministries, strategic reserve managers and critical-industry regulators can act on. A government that detects a 40% drop in container throughput at a key transshipment hub before its trading partners do can pre-position buffer stock, divert orders to alternative suppliers, and brief its industries before they face spot-market panic. That lead time is worth far more than the cost of the constellation.

What matters

A 2021 World Bank study found that supply chain disruptions cost developing economies 3-6% of annual trade value when early intervention mechanisms were absent.
SAR imagery penetrates cloud cover and operates at night, making it reliable for monitoring monsoon-affected ports and conflict-zone logistics corridors where optical alone fails.
AIS dark zones—where vessels suppress transponders near sanctioned ports—are detectable by cross-cueing RF survey data, exposing covert cargo movements that distort official trade statistics.
Strategic reserve decisions, export controls and emergency procurement must be triggered before market prices move; a 14-day intelligence lead is the difference between intervention and reaction.

Sovereignty score: 8/10 — A nation that depends on commercial vendors or allied intelligence for supply chain early warning cedes its ability to act before markets and adversaries do—sovereign sensing is the only way to guarantee unmediated, undelayed access to the signal.

Commercial data brokers license disruption analytics under terms that prohibit redistribution and can be suspended under US EAR or allied export controls during the very geopolitical crises most likely to cause supply chain shocks.
Strategic reserve activation, emergency import licensing and export controls are politically sensitive decisions that cannot be based on intelligence whose provenance, latency and completeness a foreign vendor controls.
Adversaries who know a nation's early-warning blind spots can deliberately obscure logistics disruptions—factory shutdowns disguised as maintenance, cargo diversions routed through third-country ports—that only persistent sovereign surveillance can unmask.
National economic ministries require data classified above the threshold that commercial SaaS platforms will agree to handle, particularly when the disruption signal involves sanctioned entities or dual-use goods.

Reference architecture

Payload: Dual-mode: (1) optical imager, 3m GSD panchromatic / 8m multispectral, 20km swath, for port and warehouse activity monitoring; (2) RF survey payload, 100 MHz to 6 GHz, 2km geolocation accuracy, for industrial emission and vessel transponder anomaly detection
Bus class: 12U cubesat bus, ~24kg, 80W average payload power; optical and RF payloads fly as separate spacecraft in paired orbital slots to allow independent scheduling
Orbit: Sun-synchronous LEO at 520–560km; 18-satellite walker constellation (6 planes × 3 satellites) providing sub-18-hour global revisit at equator, sub-12-hour revisit at mid-latitudes where most monitored logistics nodes cluster
Ground segment: 4-station national network (X-band downlink, S-band TT&C) co-located with existing national space or meteorological infrastructure; SatNOGS amateur-band backup for TT&C contingency; dedicated 1Gbps fibre to national economic intelligence fusion centre
