Bulk Commodity Flow Mapping

Tracking the movement of dry and liquid bulk commodities — grain, coal, ore, crude oil — by fusing satellite AIS, SAR, and optical vessel detection across global shipping lanes.

Commodity-importing and exporting nations are routinely flying blind on bulk trade flows. Official statistics lag by weeks or months, brokers shade the data, and counterparties suppress shipment details to extract better prices. A sovereign satellite stack cuts through that fog: AIS aggregation from low-orbit receivers catches vessel identity and declared cargo; SAR and optical overpasses independently confirm ship size, draft, and load state; and port-approach clustering reveals which terminals are receiving what tonnage before any manifest is filed.

The satellite stack works because bulk carriers are large, slow, and predictable. A Capesize vessel laden with iron ore sits 20 cm lower in the water per thousand tonnes — a measurable freeboard difference that well-calibrated SAR or high-resolution optical can resolve at scale. Pairing draft estimates with AIS voyage declarations and historical port calls yields commodity-level flow estimates accurate to within ±5% of later-published customs data, according to third-party validation against UN Comtrade figures.

The operational payoff is asymmetric market intelligence. A nation that knows — three weeks ahead of publication — that a major grain exporter is diverting shipments away from its own ports can act: adjust import tender timelines, pre-position food reserves, renegotiate long-term supply contracts, or simply avoid panic buying at the top of a price spike. Renting that intelligence from a commercial vendor means a foreign analyst saw it first, the data terms can be revoked, and the sovereign's own trade strategy is visible to the platform operator.

What matters

Freeboard estimation from SAR amplitude data can resolve vessel load state to within ±3–5% gross tonnage, enabling commodity volume inference without a manifest.
AIS dark periods — common in sanctioned trade and price-sensitive shipments — are the exact gaps where sovereign radar and optical overpasses deliver intelligence that no AIS feed provides.
Commodity price formation in global markets (grain, crude, LNG, metallurgical coal) is materially influenced by shipping congestion signals that a sovereign constellation can read 2–4 weeks before official data clears.
A nation dependent on a commercial trade-intelligence vendor surrenders its analytical edge the moment the vendor faces export pressure, licensing disputes, or a foreign government request for data-access logs.

Sovereignty score: 8/10 — A nation that does not own its commodity-flow intelligence will systematically negotiate at a disadvantage against counterparties who do.

Geopolitical leverage: rival states and large commodity trading houses already use commercial satellite intelligence to time export bans, adjust shipping routes, and set contract prices before importing nations have comparable data.
Supply-chain security: food and energy import decisions made on stale customs data expose nations to price spikes and supply shortfalls that earlier satellite signals would have allowed them to hedge or avoid.
Data sovereignty: commercial trade-intelligence platforms are domiciled in the US, UK, or EU and subject to export controls, subpoenas, and politically motivated access suspension — all of which can occur precisely when geopolitical tension makes the data most valuable.

Reference architecture

Payload: Dual payload per satellite: (1) AIS receiver, VHF 161.975/162.025 MHz, ≥2,000 simultaneous message capacity; (2) C-band or X-band SAR, 3–5m stripmap resolution, 80km swath, for vessel detection and draft estimation in cloud-obscured regions
Bus class: 12U cubesat bus, 14kg wet mass, 45W payload power; SAR-equipped nodes use a 60kg ESPA-class microsat with 200W solar array to support the synthetic aperture radar transmitter duty cycle
Orbit: Sun-synchronous LEO at 520–550km altitude; 18-satellite walker constellation (12 AIS-primary cubesats + 6 SAR microsats); average global revisit 4–6 hours, major shipping lane revisit under 90 minutes with orbital phasing
Ground segment: 4-station national network (X-band TT&C for SAR nodes, S-band for cubesats) co-located with existing maritime coordination centres; SatNOGS amateur-band backup for cubesat housekeeping telemetry on 435 MHz
