What types of disruptions can satellites actually detect early?

Satellites are most reliable for physical, spatially visible events: port congestion (vessel queue length and dwell time), factory shutdowns (thermal and optical change detection), flood or earthquake damage to road and rail corridors, and drought stress on agricultural supply regions. They are less useful for detecting financial or cyber-driven disruptions that leave no physical signature.

Do we need SAR, optical, and AIS, or can we start with one?

Each layer has blind spots. AIS alone misses dark vessels and land logistics. Optical alone fails in cloud cover. SAR covers cloud cover but has lower temporal resolution per satellite. A minimum viable sovereign constellation pairs spaceborne AIS reception with SAR or high-revisit optical, and adds RF sensing if budget allows. Starting with AIS-enabled nanosatellites is the lowest-cost entry point.

How does a sovereign constellation differ from simply buying data from Planet or ICEYE?

Commercial vendors can suspend service under US, EU or other jurisdictional pressure, impose licensing restrictions that limit sharing with allies, and may deprioritise your tasking during a global crisis when demand peaks simultaneously. A sovereign constellation gives your government guaranteed access, independent tasking priority, and the right to share unencumbered data with whomever you choose. It also builds domestic technical capacity.

What is a realistic revisit time for a nation-state starting constellation?

A 6–12 nanosatellite AIS/RF constellation in LEO (500–600 km, sun-synchronous) can achieve sub-6-hour revisit over key chokepoints. Adding four to six microsatellite SAR nodes brings the combined revisit for priority sites below 4 hours. Full 1-hour global revisit requires 30+ satellites, which is a Phase 2 or Phase 3 ambition for most nations.

How do we avoid false alarms that trigger unnecessary government interventions?

Multi-source fusion is the standard mitigation: an alert should require corroboration from at least two independent data streams (e.g., AIS anomaly plus optical activity reduction) before escalating to a policy decision. Machine-learning thresholds should be calibrated on at least 12 months of historical data for each monitored site. Human analyst confirmation should be required for alerts above a defined economic-impact threshold.

Which international bodies govern the AIS frequencies we need for the space segment?

The ITU-R manages AIS spectrum under Recommendation M.585-9. Space-based AIS reception (S-AIS) is coordinated under ITU Radio Regulations Article 5 and requires national administration filing through the ITU Radiocommunication Bureau before launch. IMO Resolution MSC.428(98) governs how maritime operators must manage cyber risk around AIS data, which affects how your ground system handles incoming feeds.

Can a small or middle-income nation afford this, or is it only for large economies?

A six-satellite nanosatellite AIS/optical constellation now costs between $30 million and $80 million to build and launch, with annual operations under $5 million — well within reach of economies with GDP above roughly $50 billion. The World Bank's PROBLUE and IDA windows, plus ESA's third-party mission programmes, offer concessional routes for smaller states. The economic payoff from avoiding even one major supply disruption typically exceeds the full system lifecycle cost.

How do we integrate satellite alerts into existing customs and trade-monitoring systems?

The OGC API–Features standard (OGC 17-069r4) and ISO 19168 provide vendor-neutral geospatial data interchange that can pipe disruption alerts directly into WTO-compliant trade-monitoring dashboards or national customs IT platforms. Most modern ERP and supply-chain management systems can ingest GeoJSON or Zarr-formatted alert feeds. Building the integration layer is an IT procurement question, not a satellite question, and should be scoped in parallel with the space segment.
