Coastal surveillance: Brazil
Brazil's coastline runs for thousands of kilometres from the equatorial north to the temperate south, fronting an exclusive economic zone that includes major offshore energy and dense shipping. Fixed coastal radar sees only to the horizon, so the challenge is to extend awareness from the beach out to the edge of the zone without leaving gaps that others learn to use.
Gaps beyond the horizon along a very long coast
The maritime picture thins quickly offshore: coastal radar chains cover the approaches near stations but leave stretches between them and offer nothing at the outer EEZ where illicit vessels prefer to work. Ocean surveillance satellites detect and track shipping across the whole zone, including vessels running with transponders off, turning an empty chart into a queue of contacts worth investigating. Passive radar strengthens the coastal layer without emitting a signal that a mariner could detect and route around, filling the near-shore gaps that active stations leave.
Closing the last gap at the harbour mouth
Awareness at the EEZ edge means little if a contact simply disappears into a crowded port, so the picture has to reach inshore as well as offshore. satellite-based Fish Detection adds the fishing-zone and harbour-approach detail that distinguishes ordinary traffic from suspect activity near landing points, connecting a distant satellite track to an interception a patrol boat can actually make. Because the satellites, radar and fish-detection analytics come from independent, non-aligned makers, the maritime picture is held by Brazil's naval and maritime authorities, with localisation arrangements scoped per programme and subject to export controls and end-use approvals.
How engagement works in Brazil
Unstrat engages Brazil as an independent, non-aligned prime vendor: one accountable team, end-use certified, sustained in-region rather than a distribution arrangement. A sensible programme starts with a satellite baseline that shows where traffic and anomalies concentrate along the coast, layers passive radar and observation drones onto the busiest approaches, and grows into a maritime watch the country runs itself. The non-aligned position matters because a nation's maritime picture should answer to its own command, not to a foreign provider's tasking priorities.
Extending awareness from the beach to the EEZ edge
A coastal-surveillance engagement begins with a briefing that maps Brazil's own concerns along a coast running from the equatorial north to the temperate south: where traffic and anomalies cluster, and how a distant track must be followed to an interception a patrol boat can make. Before any representation, export-control and end-use confirmation is settled, so satellite, radar and drone coverage is proposed on terms that can lawfully be delivered. Capability is matched to real conditions: wide-area detection tuned to the outer EEZ, passive radar sited to close near-shore gaps without emitting, observation drones chosen for the harbour approaches where a contact would otherwise vanish. Sustainment is phased in-region, from a satellite baseline through the busiest approaches toward a watch the country runs itself, with localisation arrangements scoped per programme, subject to export controls and end-use approvals. As one accountable channel, Unstrat keeps the maritime advantage answering to national command.

Adjacent priorities in Brazil
Illegal, unreported and unregulated fishing drains coastal economies and undermines sovereignty over the exclusive economic zone. Persistent satellite surveillance, satellite-data fisheries analytics and aerial ISR give maritime authorities the picture they need to intercept offenders, without depending on a major power's data feed.
Problem pagePiracy raises insurance costs, deters shipping and endangers seafarers. Space-based vessel monitoring, aerial patrol and hardened port and vessel systems let coastal states detect threats early and protect the shipping lanes their economies depend on.
Problem pageBrazil's major ports concentrate the trade of a continental economy into a few exposed footprints, handling commodities, containers and offshore energy traffic. That concentration makes a port vulnerable from the water, the air and the network at once, so it has to be secured as a whole rather than gate by gate.

Brazil: security context
Brazil's continental scale shapes its priorities: surveillance of vast Amazon and border regions, protection of an exclusive economic zone and offshore energy, security of critical infrastructure, and counter-narcotics operations across remote terrain. It is an environment defined by distance, where awareness must reach places that are hard to hold.
One accountable, non-aligned partner gives Brazil a coherent counterpart for those priorities, Amazon and border surveillance, EEZ and offshore energy protection, infrastructure security and counter-narcotics support. A defence ministry gains end-use certified equipment and localisation arrangements scoped per programme to match the mission and budget.
About this challenge
Coastal radar sees only so far, and gaps between stations are exploited daily. Passive radar that adds coverage without emitting, satellite vessel detection and satellite-data fisheries analytics extend the maritime picture from the beach to the edge of the EEZ.
Frequently asked questions
How does this extend Brazil's picture beyond coastal radar?
Coastal radar reaches only to the horizon, so ocean surveillance satellites carry the picture out across the whole EEZ, including vessels running dark, while passive radar fills the near-shore gaps between stations without emitting. Together they close the stretches that illicit traffic prefers. We would be glad to brief your team on sequencing coverage along the coast.
Can it connect an offshore detection to an interception inshore?
Yes. Satellite-based Fish Detection adds fishing-zone and harbour-approach detail near landing points, so a distant satellite track can be followed to where a patrol vessel can actually intercept, rather than being lost as a contact nears a busy port.
Who controls the maritime picture once it is running?
Brazil's naval and maritime authorities. The sensing comes from independent, non-aligned makers, so the picture is retained nationally, with localisation arrangements scoped per programme and subject to export controls and end-use approvals.
