Iceberg Tracking

Continuously detecting, classifying and tracking icebergs across polar and sub-polar waters using satellite SAR, optical and AIS-fusion to protect shipping, infrastructure and fisheries.

Icebergs kill ships, destroy subsea pipelines and shut down offshore platforms without warning. The North Atlantic alone calves roughly 40,000 icebergs annually from Greenland's glaciers, and Southern Ocean drift puts Antarctic bergs in the path of every vessel rounding Cape Horn or servicing Antarctic research stations. National hydrographic offices and coast guards that rely on a commercial vendor for iceberg position data discover—at the worst possible moment—that the service goes dark when contracts lapse, that detection thresholds are tuned for paying customers in other regions, and that classified maritime routes are visible in the tasking requests they must submit.

A sovereign constellation fixes all three problems. A small walker of SAR microsatellites at high inclination resolves bergs down to 20 metres in any weather and polar night, while a complementary optical and multispectral layer confirms surface melt signatures that radar alone misses. On-board processing compresses detections to compact vector products before downlink, so a single polar ground station with a 4-hour contact window still delivers fresh positions every orbit. Fusion with LRIT, AIS and bathymetric hazard layers produces a national Iceberg Threat Layer that no vendor can embargo.

The operational payoff is immediate and measurable. Shipping companies, offshore operators and naval vessels receive authoritative, nationally certified hazard bulletins rather than third-party estimates of unknown provenance. Insurance underwriters accept sovereign-certified tracks as evidence for route-deviation decisions, cutting premium disputes. And when a berg grounds in shallow water near a fishing ground or a subsea cable corridor, the national authority has the positional authority to issue binding closures—backed by its own data, not a screenshotted commercial product.

What matters

Small bergs under 100 metres—the class that sank Titanic—are below the detection floor of most commercial optical services and require dedicated SAR with sub-20m resolution.
Iceberg drift is non-linear: a single storm event can displace a berg 60–80 km in 24 hours, making yesterday's commercial position file operationally useless.
Nations with Arctic territory or Southern Ocean EEZ obligations bear legal liability under SOLAS if they publish hazard notices derived from data they cannot independently verify.
US National Ice Center iceberg bulletins cover global named bergs but exclude the smaller, shipping-relevant population; that coverage gap is the sovereign mission.

Sovereignty score: 8/10 — A nation that cannot independently detect and certify iceberg positions cannot discharge its SOLAS hazard-notification duties, protect its own offshore infrastructure, or keep commercial shipping lanes open without depending on a foreign government's goodwill.

Legal exposure: SOLAS Chapter V creates a positive obligation on coastal and flag states to publish ice hazard notices; relying on a commercial or foreign-government feed creates an unverifiable chain of custody that will not survive a maritime accident inquiry.
Geopolitical leverage: Arctic territorial disputes mean that a neighbour controlling the iceberg data feed can degrade or delay position updates affecting contested shipping corridors—a low-cost, deniable form of economic pressure.
Infrastructure protection: Nations with offshore oil platforms, subsea cables or fish-farm installations in iceberg-prone waters cannot outsource the decision to evacuate or shut down to a vendor whose service-level agreement contains force-majeure clauses.
Supply-chain risk: High-resolution SAR data for polar regions is subject to US EAR and ITAR export controls on the most capable commercial sensors; a sovereign SAR payload built to European or Indian specifications removes that single point of failure.

Reference architecture

Payload: C-band SAR, 3m stripmap / 10m wide-swath dual-pol, supplemented by a 5-band VNIR multispectral imager at 10m GSD for surface-melt classification; each satellite carries both payloads on a shared bus
Bus class: ESPA-class microsat, 140kg, 600W total power, 300W payload allocation, dual-redundant attitude control for high-inclination manoeuvring
Orbit: Near-polar LEO at 500–550km, 97.5° inclination sun-synchronous, 8-satellite walker constellation providing 90-minute revisit above 60°N/S; two satellites in higher-inclination frozen orbits at 86° for deep-polar coverage
Ground segment: Primary polar ground station (Svalbard, Tromsø or national equivalent) providing 6–8 contacts per satellite per day; secondary mid-latitude X-band station for contingency downlink; SatNOGS UHF beacon network for telemetry health monitoring
