Ocean surveillance satellites
Maritime domain awareness from orbit

What it is
Ocean-surveillance satellites provide wide-area maritime domain awareness from orbit, detecting, tracking and characterising vessels across an exclusive economic zone and the open ocean beyond the reach of coastal radar and patrol assets.
How it is employed
Space-based sensing is tasked against national priorities: EEZ enforcement, illegal-fishing detection, smuggling routes and grey-zone activity. Detections cue patrol vessels and aircraft, turning scarce hulls into a response force rather than a search force.
Why it matters now
Illegal, unreported and unregulated fishing drains coastal economies across Africa and the Indian Ocean, and grey-zone maritime activity is rising across the region's chokepoints. Nations that depend on shared coalition feeds see their own waters through someone else's priorities.
Procurement & integration
Maritime surveillance can be procured as a data service, a dedicated tasking arrangement, or sovereign capability with national ground segment. Unstrat structures the model to the buyer's ambition and budget, with a growth path from service to ownership.
Capability
- Multi-source fusion: AIS tracks, SAR detections, RF geolocations and optical imagery merged with weather, port calls and intelligence into one operating picture
- Dark-vessel tracking: cross-matches AIS gaps against radar and RF layers to surface ships hiding their transponders
- Sovereign delivery contract: tasking on your priorities, downlink to antennas inside your borders, processing inside your jurisdiction, so no raw data leaves the country
- Serves navy, coast guard, fisheries enforcement, customs and search-and-rescue from one platform with role-based access
- Sovereign hosting and national tuning: the alerting logic is yours, not a foreign-supplied black box
- Staged build-out: a two-layer AIS + radar picture in 6–9 months, full multi-source platform in 12–18, classified national deployment in 18–24

What are Ocean surveillance satellites?
Ocean surveillance satellites are Unstrat's Sea (Maritime Domain) capability: Space-based maritime domain awareness delivered under a sovereign contract: satellites tasked on your priorities, downlink to ground stations on your soil, processing inside your jurisdiction. Fuses AIS, radar, optical and RF layers into a single operating picture of your EEZ and the open ocean beyond coastal radar.
How do Ocean surveillance satellites work?
Ocean surveillance satellites deliver their effect through Multi-source fusion: AIS tracks, SAR detections, RF geolocations and optical imagery merged with weather, port calls and intelligence into one operating picture, Dark-vessel tracking: cross-matches AIS gaps against radar and RF layers to surface ships hiding their transponders and Sovereign delivery contract: tasking on your priorities, downlink to antennas inside your borders, processing inside your jurisdiction, so no raw data leaves the country, capabilities matched to the requirement and confirmed under briefing rather than published.
Who makes Ocean surveillance satellites?
Ocean surveillance satellites are built by The Satellite Programme Partner, whose focus is satellites & sovereign space programmes. Unstrat represents The Satellite Programme Partner to government and enterprise buyers worldwide as an independent, non-aligned prime vendor.
Who uses Ocean surveillance satellites?
Government and enterprise buyers acquire Ocean surveillance satellites to address illegal fishing, drug smuggling, piracy & armed robbery at sea, port security, coastal surveillance and human trafficking & irregular migration across the maritime domain, matched to the mission and accountable to them, not to a foreign vendor's government.
Why choose Ocean surveillance satellites over a major-power alternative?
Ocean surveillance satellites are sourced from an independent, non-aligned manufacturer, so they carry no major-power disclosure rules, upgrade-locks or political ramifications. Concretely: sovereign delivery: tasked on your waters, downlinked on your soil, processed in your jurisdiction. The capability is accountable to you, not to a foreign vendor's government and its release schedule.
How are Ocean surveillance satellites procured, and where can it be exported?
Sovereign maritime awareness from orbit, tasked on your priorities rather than a coalition's. Every engagement begins with a briefing, and export eligibility is confirmed per market under briefing rather than published. Where controlled capabilities are involved, the classification and end-user-certificate chain is confirmed first. Ocean surveillance satellites are then sustained in-region by one accountable team from briefing through long-term operation.
Questions buyers ask
What is space-based maritime domain awareness?
It is wide-area understanding of a nation's waters from orbit, detecting, tracking and characterising vessels across the exclusive economic zone and the open ocean beyond the reach of coastal radar and patrol assets. Space-based sensing is tasked against national priorities such as EEZ enforcement, illegal-fishing detection and grey-zone activity.
Why not just rely on coalition maritime feeds?
Nations that depend on shared coalition feeds see their own waters through someone else's priorities, and those feeds serve coalition priorities first. Ocean-surveillance capability tasked on the buyer's flag turns an EEZ from a line on a map into something governed, without waiting behind another government's queue.
Can maritime surveillance grow from a data service into sovereign capability?
Yes. Maritime surveillance can be procured as a data service, a dedicated tasking arrangement, or sovereign capability with a national ground segment. We structure the model to the buyer's ambition and budget, with a growth path from service toward ownership rather than perpetual subscription.
Turning scarce patrol hulls into a response force rather than a search force
That is the point of wide-area sensing when a nation has few hulls. Detections from orbit cue patrol vessels and aircraft, so scarce assets respond to known contacts rather than searching empty water. The capability is tasked on national priorities, which is what makes the cueing worth the fuel.
Satellite maritime surveillance against a coastal-radar network for EEZ coverage
Coastal radar sees to its horizon; space-based sensing reaches the whole EEZ and the open ocean beyond it. The comparison sets out the trade neutrally. The doctrine argument is that a nation with a large maritime zone needs the orbital layer to cue the coastal and patrol layers, not to replace them.
Ocean surveillance where tasking and processing stay under national control
A sovereign contract tasks satellites on the buyer's priorities and can keep the growth path aimed at national ownership. The sovereignty question is who sets the tasking queue and where the processing sits, which is exactly what a data-service arrangement and a national ground segment decide differently.
Optical or radar sensing for a national maritime picture
Radar sees through cloud and darkness and detects vessels that are not cooperating; optical adds detail. A maritime picture usually needs both, together with AIS and RF, because the value is in the disagreement between layers. The comparison page explains the optical-versus-radar trade for imaging programmes.
Avoiding a perpetual data-subscription dependency when starting with a service
By writing the growth path into the programme from the outset. The service stage should build toward a dedicated arrangement and then a sovereign ground segment, so each payment moves the nation toward ownership rather than deeper into subscription. That structured path is exactly what the comparison contrasts with an open-ended data feed.
See: Growth path in the comparisonSovereign ground segment against a data service
We depend on an allied maritime feed today. At what point does a nation build its own ocean-surveillance capability?
The trigger is usually a priority conflict: a moment when the coalition feed serves coalition priorities and your waters wait. A dedicated tasking arrangement removes the queue, and a sovereign ground segment removes the dependency entirely. We structure the growth path so each stage builds toward ownership rather than deeper subscription.

How does ocean surveillance fit into a wider maritime domain awareness architecture rather than a single satellite buy?
Orbital sensing is one layer of maritime domain awareness, alongside satellite fisheries analytics and hardened port infrastructure. Built as an architecture, detections cue patrols, fisheries intelligence flags unregulated fishing, and the port systems that receive the picture stay trustworthy. We represent those layers through one accountable channel with a growth path from service to ownership.

Can a navy run an ocean-surveillance programme when it has no space engineers of its own?
The programme can begin as a data service or tasking arrangement that needs no national space cadre, then grow toward a sovereign ground segment as the people pipeline develops. The whole point of structuring the growth path is that the nation is not forced to own everything on day one, but is not locked out of ownership either.
See: Sovereign space infrastructure capabilityHow we deliver programmes
What performance figures does the site publish for ocean-surveillance satellites, and what should we specify?
This reference page describes the capability and its procurement models rather than resolution, revisit or detection figures, so any number quoted without a defined coverage requirement is guesswork. Specify the waters, the revisit and the vessel classes that matter, then compare arrangements on the same deliverable. The comparison page sets out what each supplier route actually provides.
If we buy a maritime detection subscription, whose priorities decide what our satellites look at?
In a coalition-feed or subscription model, tasking priority follows the owner's priorities first. A sovereign contract tasks on the buyer's priorities and is accountable to the buyer's flag. That distinction is the reason we frame the choice as detections, satellites or a picture you own, rather than a single product comparison.
How does ocean surveillance connect to protecting the ports and networks that receive the picture?
A maritime picture is only as trustworthy as the infrastructure that carries it, which is why maritime cybersecurity sits in the same architecture. Hardened port and network systems keep the picture reliable, so the awareness that cues patrols is not itself an attack surface. We represent the surveillance and cyber layers through one accountable channel.
Grey-zone activity is rising across our chokepoints. How does persistent orbital sensing change what a coast guard can do about it?
Persistent wide-area sensing surfaces activity that coastal radar and patrols never see, and tasked on national priorities it can watch smuggling routes and grey-zone behaviour across the EEZ and beyond. The value is turning scarce hulls into a response force, cued to the contacts that matter rather than patrolling blind.
