Coastal surveillance: Chile
Chile's maritime frontage is a single, near-continuous ribbon of Pacific coast running the length of the country, backed by fjords, channels and offshore islands that break a coastal radar's line of sight. Watching so long and so intricate a shoreline is less about one dense sensor wall than about closing the shadows between stations spread thinly along a vast frontage.
A long, broken coast that outruns fixed radar
Coastal radar reaches only so far, and along a shoreline of this length the gaps between stations are the working reality rather than the exception. A vessel that hugs the coast or slips behind an island can cross a whole sector unseen. Passive radar adds coverage without emitting, so a station can be sited to fill a shadow between existing sites without advertising its own position or drawing a jammer. Satellite vessel detection then keeps a standing picture over the open approaches where no shore station can watch, turning an empty seaward map into a queue of contacts worth resolving.
From the beach to the edge of the zone
What makes the Chilean picture demanding is the coupling of a sheltered inshore world of channels and harbours with a wide, exposed exclusive economic zone offshore. The two need to read as one continuous track, not two disconnected views. Observation drones add the near-quay and inshore detail that distinguishes legitimate movement from suspect activity close in, while the overhead layers carry the picture out to the zone edge. Because these capabilities are drawn from independent, non-aligned makers, the maritime picture is retained under national control, with localisation arrangements scoped per programme and subject to export controls and end-use approvals.
How engagement works in Chile
Unstrat engages as an accountable, non-aligned single channel: one team representing the manufacturers directly, with end-use certified equipment and in-region sustainment rather than a distribution arrangement. A sensible programme begins by mapping where the coastal shadows genuinely concentrate along the frontage, then layers passive sensing, satellite detection and observation drones onto that baseline so the coastal watch is one the maritime authority runs itself. The non-aligned position matters because Chile's own picture of its waters should answer to national command rather than a foreign release schedule.
Standing up the coastal watch, sector by sector
Work opens with a briefing that reads the frontage as the maritime authority experiences it: which channels, islands and open approaches leave the coastal picture shadowed today. No representation of any maker proceeds until end-use is confirmed and the export-control and end-use approvals are in hand. Only then is passive sensing, satellite vessel detection and observation drones matched to the operator's real siting and manning conditions rather than an idealised layout, so each station closes a shadow the crews can actually service. Sustainment is brought in-region in phases, so the advantage of a continuous watch is protected as the layers extend from the beach to the zone edge and the mission stays one national command runs itself, with localisation arrangements scoped per programme, subject to export controls and end-use approvals.

Adjacent priorities in Chile
Chile's exclusive economic zone reaches far into the southeast Pacific, where cold, productive currents draw distant-water fleets to the outer edge of national waters and squid and pelagic stocks move across the boundary with the season. Policing a zone this deep against fleets that gather just outside it is fundamentally a problem of persistent awareness at range, not of patrol density alone.

Problem pagePorts concentrate national trade in a small, exposed footprint, vulnerable from the water, the air and the network. Inshore passive radar, vessel monitoring from orbit, counter-drone defence and maritime cyber protection secure the gateway end to end.

Chile: security context
Chile's long Pacific coast and rugged interior shape its priorities: maritime domain awareness across a vast ocean frontage, protection of its exclusive economic zone and fisheries, security of mining regions, and readiness for disaster response. It is an environment where wide-area awareness and resilience to natural hazards matter equally.
One accountable, non-aligned partner gives Chile a coherent counterpart for those priorities, Pacific maritime domain awareness, EEZ and fisheries protection, mining-region security and disaster response. A defence ministry gains end-use certified equipment and localisation arrangements scoped per programme rather than promised in advance.
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 coastal surveillance suit Chile's very long shoreline?
The length and the broken geometry of channels and islands mean fixed radar leaves shadows between stations along the whole frontage. Passive radar fills those gaps without emitting, and satellite vessel detection watches the open approaches beyond any shore station's reach, so the two together turn a thin sensor line into continuous coverage. We would be glad to brief your team on where to close the shadows first.
Can the inshore channels and the offshore zone be watched as one picture?
Yes. Observation drones resolve the sheltered inshore detail near quays and channels, while satellite detection and passive radar carry the track out to the edge of the exclusive economic zone. The layers are designed to read as a single continuous picture from the beach to the seaward boundary rather than two disconnected views.
Does Chile retain control of its own maritime picture?
Yes. The sensing is drawn from independent, non-aligned makers, so the imagery and tracks are retained under national control, with localisation arrangements scoped per programme and subject to export controls and end-use approvals, not conditional on a foreign government releasing a pass.
