Illegal fishing: Indonesia
Indonesia's exclusive economic zone wraps thousands of islands and the busy straits between them, and it is at the far edges of that zone (where patrol vessels rarely reach) that foreign trawlers work the banks and land catch quietly. For an archipelagic state, the theft is invisible until stocks thin and the artisanal fleets that feed coastal communities come home empty.
A zone too large and dispersed to patrol
The scale of the archipelago is what makes the theft possible: an exclusive economic zone spread across an immense span of sea has more open water than any fleet can watch, and vessels that switch off their transponders vanish from cooperative tracking precisely where enforcement is weakest. Fisheries inspectors see only what comes ashore legally, so a single interception proves nothing about a pattern and a dark contact cannot be prosecuted on suspicion. What is missing is a continuous, defensible record of who was fishing where, one that does not depend on a distant partner choosing to share the relevant satellite pass at the relevant moment.
Sensing that builds a prosecutable picture
Ocean surveillance satellites provide the wide-area layer, detecting and tracking hulls across the zone independently of any transponder, so a trawler running dark still appears in the picture and the movement patterns that mark a vessel working a bank stand out from ordinary transit. Modular aerial platform kits then close on the contacts that matter, confirming gear in the water and identity on the hull so an interception rests on evidence rather than a hunch, while satellite-based Fish Detection adds fisheries analytics (fishing-zone patterns and IUU indicators read from orbit) that sharpen where the fleet is likely working. Because these capabilities come from independent, non-aligned makers, the imagery and tracks are held under national control and admissible in an admiralty case without waiting on a foreign government to release a pass. Retention and any localisation are scoped per programme and subject to export controls and end-use approvals.
How engagement works in Indonesia
Unstrat engages Indonesia as an independent, non-aligned prime vendor: one accountable team representing the manufacturers directly, with end-use certified equipment and in-region sustainment rather than a distribution arrangement. A programme typically begins by establishing a satellite baseline over a season, mapping where and when the theft concentrates across the zone before patrol assets are committed, then layers drones and satellite fish-detection analytics onto that baseline and coordinates interception from a single operations picture. The end state is a fisheries watch the maritime authority runs itself, with crews trained in-region and localisation arrangements scoped per programme.
From first briefing to a fisheries watch under your flag
Engagement opens with a briefing to the maritime authority, and no capability is represented until export-control and end-use approvals are confirmed for the archipelago's specific fisheries mission, a discipline that protects the programme rather than delaying it. From there the emphasis is matching sensing to real operating conditions: how far the theft sits from patrol reach, which banks are worked hardest, how monsoon and sea state shape a season. A satellite baseline is established first to map where and when the theft concentrates, giving planners the advantage of committing scarce patrol assets against evidence rather than rumour; drones and satellite-based Fish Detection analytics are then layered onto that baseline and fused into one prosecutable picture. Sustainment proceeds in phases, with in-region crews trained to task the sensors and build admiralty cases, and localisation arrangements scoped per programme, subject to export controls and end-use approvals.

Adjacent priorities in Indonesia
An archipelago of thousands of islands has more coastline than any chain of radar stations can cover, and the straits and channels between the islands are precisely where a fixed, emitting radar reveals its own gaps. Indonesia's maritime picture is built from stations that see only to the horizon, leaving the mid-water and the far approaches routinely transited in the spaces a planning map does not show.
Problem pageIndonesia sits astride some of the world's busiest sea lanes, and the narrow, island-fringed straits that carry that traffic are exactly where a small craft can close on a vessel unseen. For an archipelagic trading nation, waters that acquire a reputation for armed robbery deter the port calls and transits its economy depends on long after any single incident.
Problem pageContraband, fuel and untaxed goods cross borders wherever surveillance is thinnest, draining customs revenue. Wide-area overhead surveillance and low-observable radar coverage let enforcement concentrate where the traffic actually moves.

Indonesia: security context
Indonesia's vast archipelago shapes its priorities: maritime domain awareness across thousands of islands and straits, protection of its exclusive economic zone and fisheries, readiness for disaster response, and countering piracy along busy sea lanes. It is an environment where scale and dispersal define every security task.
One accountable, non-aligned partner gives Indonesia a coherent counterpart for those priorities: archipelagic maritime domain awareness, EEZ and fisheries protection, disaster-response capability and counter-piracy. A defence ministry gains end-use certified equipment and localisation arrangements scoped per programme rather than promised in advance.
About this challenge
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.
Frequently asked questions
How can Indonesia detect illegal fishing across so vast an archipelago?
By starting from orbit. Ocean surveillance satellites detect and track vessels across the whole zone independently of any transponder, so a trawler running dark in the far reaches of the EEZ still appears in the picture. Drones then close in to confirm gear and identity, turning a wide, unwatchable span of sea into a short queue of documented leads. We would be glad to brief your team on establishing that baseline across the priority fishing grounds first.
Will satellite-derived fishing evidence hold up in an Indonesian court?
It can, which is why control of the data matters. Because the sensing comes from independent, non-aligned suppliers, the imagery and tracks are retained under national control and can be produced in an admiralty case without waiting on a foreign government to declassify a pass. Retention and any localisation are scoped per programme and subject to export controls and end-use approvals.
How does satellite-based fish detection add to wide-area coverage against illegal fishing?
Ocean surveillance satellites give the wide-area picture of hulls across the zone; satellite-based Fish Detection fuses earth and space data into fisheries analytics: fishing-zone advisories and IUU indicators read from orbit. Together they distinguish likely fishing activity from ordinary transit, sharpening a distant detection into a lead enforcement teams can act on.
