Why can't a country just buy AIS data from Spire or MarineTraffic instead of building its own satellite?

Purchasing a commercial feed gives you a processed data product subject to the vendor's licensing terms, data-retention policies, and geopolitical alignment. In a sanctions regime or trade dispute, a foreign vendor can throttle or cut access without notice. Owning even a small S-AIS nanosatellite constellation keeps raw data sovereign, enables custom retention windows, and removes the single-vendor dependency that commercial feeds create.

What satellites does this application actually require — is a full constellation necessary?

A minimum viable sovereign capability can start with four to six nanosatellites in a sun-synchronous LEO orbit tuned to VHF AIS reception, achieving 3–4 hour revisit for major shipping lanes within national interest zones. Full global coverage with sub-90-minute revisit requires 20–30 spacecraft. Most nations begin with a bilateral data-sharing agreement while their first tranche launches, then reduce dependency incrementally.

How does satellite tracking differ from the existing port-authority and customs IT systems a country already operates?

Port IT systems see a vessel only when it declares arrival or enters a reporting zone; satellite AIS and RF geolocation track the vessel continuously at sea, regardless of declaration. This closes the gap between departure from a foreign port and domestic port entry — a window that is frequently exploited for transshipment fraud, sanctions evasion, and misdeclaration of cargo origin.

Can the same satellite infrastructure serve both maritime and land-border logistics tracking?

Yes, with augmentation. S-AIS payloads handle maritime assets. Land logistics visibility requires either an IoT/LPWAN payload (such as a LoRa or NB-IoT hosted payload for truck and rail GPS beacons) or fusion with terrestrial AIS-equivalent systems such as GSM-based track-and-trace. Many microsatellite platforms support dual payloads, so a nation can host both an AIS receiver and an IoT gateway on the same bus.

What is the WCO SAFE Framework and why does it matter for this application?

The World Customs Organization's SAFE Framework of Standards sets the international baseline for data exchange between customs administrations, including advance cargo information requirements. Sovereign satellite tracking generates verified, timestamped positional data that can be fed into WCO-compliant Customs-to-Customs data pipelines, strengthening a nation's standing in mutual-recognition agreements and reducing the inspection burden placed on its exporters abroad.

How accurate is satellite-derived position data for identifying which terminal or berth a vessel occupies?

Standard S-AIS position accuracy from GNSS-equipped transponders is typically better than 10 metres, sufficient to resolve individual berths within a port. The limitation is not position accuracy but message reception probability: in congested anchorages with hundreds of simultaneous transmitters, packet collision rates can rise above 30%, requiring multi-satellite reception or terrestrial AIS augmentation to maintain continuity.

What are the spectrum licensing obligations for operating a satellite AIS receiver?

Satellite AIS reception operates on VHF channels 87B and 88B (161.975 MHz and 162.025 MHz) as defined in ITU-R M.1371-5. Spacecraft operators must coordinate with the ITU Radio Regulations Bureau through their national administration and file orbital parameters under the ITU Radio Regulations Article 9 procedure. Reception-only payloads carry lower coordination burden than transmitting payloads but still require national filing.

How long does it take to go from satellite procurement to operational cross-border tracking data?

A nanosatellite AIS mission procured as a hosted payload or turnkey nanosatellite from an established manufacturer (e.g. AAC Clyde Space, GomSpace, or Satellogic bus derivatives) typically has a 18–30-month timeline from contract signature to on-orbit commissioning, including ITU coordination. Interim capability can be stood up within weeks by negotiating a data-sharing agreement with an existing commercial provider, then migrating to sovereign data once the constellation is live.
