Coastal surveillance: Papua New Guinea
Papua New Guinea's coastline runs for thousands of kilometres around a mountainous mainland and a scatter of islands, far more than any chain of radar stations can hold. Between and beyond the fixed sites lie predictable gaps that smugglers and unauthorised approaches learn to use, so the approaches appear defended on a map while being routinely transited in the spaces the map does not show.
More coastline than any radar chain can cover
Coastal awareness here is defined by a mismatch of scale: a long, indented shoreline broken by straits and island passages against a small number of emitting radar stations that reach only to the horizon. Each fixed station tells anyone operating illegally exactly where the coverage begins and ends, and the mid-water and the far edge of the zone stay effectively unwatched. The maritime authority is left stitching together a fragmented picture from sites that cannot follow a contact from open water through the passages to the shore, the seams where smuggling, illegal fishing and unauthorised landings concentrate.
Filling the seams without advertising them
Passive Radar is the natural gap-filler for an archipelago: by exploiting ambient signals it adds detection and tracking coverage without emitting, so it extends the picture into the seams of the radar chain without telling an adversary where the new coverage lies or offering anything to jam. Ocean surveillance satellites detect and track vessels out to the edge of the exclusive economic zone, catching movement long before it reaches coastal radar range, while satellite-based Fish Detection adds fisheries analytics that flag anomalous activity near the shore. All three come from independent, non-aligned makers, so the coastal picture is owned and tasked by the country, retained under its control, with localisation arrangements scoped per programme and subject to export controls and end-use approvals.
How engagement works in Papua New Guinea
As an accountable single-channel partner, Unstrat fields one team that represents the manufacturers directly, with end-use certified equipment and in-region sustainment rather than a distributor handoff. The first phase targets the known gaps: passive coverage added where the existing chain is weakest and a satellite baseline established over the wider approaches, revealing how current coverage is actually being circumvented through the island passages. Coverage is then made continuous, fusing passive radar, satellite tracking and satellite fish-detection analytics into a single picture that follows a contact from open water to the quayside, with in-region crews trained to run and sustain each layer. The outcome is a coastline watched as a whole under national control.
Closing the seams, one phase at a time
A coastal engagement here begins by mapping where Papua New Guinea's radar chain actually goes quiet (the straits and island passages transited in the spaces a map does not show), so the briefing frames the seam problem before any hardware is discussed. End-use confirmation and export-control clearance come before Unstrat represents the manufacturers, keeping a single accountable channel rather than a distributor handoff. Capability is matched to the operator's real conditions: passive coverage placed where emitting stations would only advertise themselves, satellite tracking sized to the wider approaches, satellite fish-detection analytics for the inshore picture. Fielding is phased, with in-region crews trained to run and sustain each layer as it lands. The advantage is continuous coverage that follows a contact from open water to shore, protecting approaches the authority now watches as one mission, with localisation arrangements scoped per programme, subject to export controls and end-use approvals.

Adjacent priorities in Papua New Guinea
Papua New Guinea holds one of the largest and most productive tuna zones in the Pacific, yet its exclusive economic zone wraps around an archipelago whose distances swallow a handful of patrol assets. Distant-water fleets work the seams between the islands where surveillance rarely reaches, and the loss is felt in both national revenue and the coastal fisheries that feed dispersed communities.

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.

Papua New Guinea: security context
Papua New Guinea's rugged islands and long coastlines shape its priorities: maritime domain awareness across dispersed waters, protection of its exclusive economic zone and fisheries, surveillance of remote interior regions, and readiness for disaster response. It is an environment where difficult terrain and dispersal define the security task.
An accountable single-channel engagement gives Papua New Guinea a coherent counterpart for those priorities, maritime domain awareness, EEZ and fisheries protection, remote-area surveillance and disaster-response capability. A security agency gains end-use certified equipment, disciplined export-control handling 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 do you cover the gaps between Papua New Guinea's coastal radar stations?
With passive coverage. Passive Radar exploits ambient signals to detect and track without emitting, so it fills the predictable seams between fixed, emitting stations, extending the coastal picture into the island passages without advertising where the new coverage is or offering anything for an adversary to jam.
How is the maritime picture extended beyond radar range around the islands?
Ocean surveillance satellites detect and track vessels out to the edge of the exclusive economic zone, including those running dark, catching movement long before it reaches coastal radar range. That wide-area layer turns a horizon-limited chain into awareness across the whole approach to a dispersed coastline.
Is Papua New Guinea's coastal picture dependent on a foreign data feed?
No. The passive radar, satellites and satellite fish-detection analytics are all independent and non-aligned, so the coastal picture is tasked and owned by the country and retained under its control, with localisation arrangements scoped per programme and subject to export controls and end-use approvals, rather than stitched together from a feed a foreign partner can filter or withdraw.
