Trade Sanction Compliance

Using satellite SAR, optical imagery, RF monitoring and AIS correlation to independently verify that sanctioned vessels, ports and commodity flows are not circumventing trade restrictions.

Sanctions regimes live and die on evidence. When a nation imposes or enforces trade restrictions, it must be able to prove—to courts, trading partners and international bodies—that sanctioned entities are actually moving goods. Commercial intelligence services can supply some of that evidence, but they answer to their own shareholders and jurisdictions, not yours. A sovereign satellite programme gives enforcement agencies unimpeachable, chain-of-custody imagery and signals data that cannot be withheld, redacted or quietly delayed when a vendor judges the political moment inconvenient.

The satellite stack for sanction compliance fuses at least three data streams. Synthetic aperture radar catches vessels conducting ship-to-ship transfers in international waters regardless of weather or darkness. RF survey payloads detect AIS spoofing and flag vessels transmitting false identity or position. Optical revisits confirm cargo type, vessel markings and port-berth occupancy at the declared or suspected loading facility. Together, those streams let analysts reconstruct a complete transit chain—from disputed refinery jetty to receiving port—with timestamps and geolocation accurate enough to hold up in arbitration.

The operational outcome is leverage. A nation that can hand its treasury, foreign ministry or judiciary a sovereign imagery package—unimpeachable, produced domestically, not subject to foreign export-control or vendor redaction—negotiates sanctions policy from a position of strength. It can also support allies with shared tasking, turning the constellation into a diplomatic asset rather than a budget line.

What matters

Ship-to-ship transfers conducted with AIS switched off are invisible to port records but visible to SAR satellites with 1–3 m resolution.
AIS spoofing has risen sharply since 2022; RF geolocation from orbit is the only scalable method to detect false identity broadcasts at sea.
Sanctions evidence gathered by a foreign commercial vendor can be legally challenged as third-party hearsay; sovereign-collected imagery has unbroken domestic chain of custody.
Sanctioned commodity flows increasingly route through opaque jurisdictions where ground-based customs data is unavailable or fabricated.

Sovereignty score: 9/10 — A nation that depends on foreign vendors for sanctions evidence surrenders the evidentiary chain and, with it, the credibility of its enforcement posture.

Foreign commercial imagery providers operate under their home government's export-control and national-security law; data can be withheld or delayed precisely when it is most needed for enforcement or diplomacy.
Sanctions cases reaching domestic courts or international arbitration require unbroken chain-of-custody for imagery evidence; data purchased from a third-party platform cannot meet that standard as reliably as domestically collected and processed material.
Adversarial states actively develop countermeasures—flag changes, identity spoofing, offshore transshipment—tailored to the coverage gaps of known commercial constellations; a sovereign system with classified tasking schedules is far harder to game.

Reference architecture

Payload: Dual-mode: (1) X-band SAR, 3 m stripmap / 1 m spotlight resolution, 50 km swath, for vessel detection and ship-to-ship transfer imaging; (2) RF survey payload, 100 MHz to 6 GHz, AIS band monitoring plus wideband emitter geolocation to 500 m CEP
Bus class: ESPA-class microsat, 150–180 kg wet mass, 600 W payload power; dual-payload integration drives mass above nanosatellite class
Orbit: Sun-synchronous LEO at 525–550 km altitude; 18-satellite walker constellation (3 planes × 6 satellites) delivering sub-4-hour revisit over primary sanction-watch maritime zones; supplemented by opportunistic tasking
Ground segment: Primary mission control and X-band downlink at a nationally operated site; secondary downlink at a geographically separated backup station; encrypted X-band TT&C; air-gapped evidence archive with hardware security module timestamping for legal chain of custody
