Coastal surveillance: Fiji
Fiji's coastline is not one shore but hundreds, scattered across an archipelago whose reefs and passages create far more approaches than any radar chain can hold. Between and beyond the fixed stations lie predictable gaps that unauthorised approaches and smuggling learn to use, so the seas around the islands look defended on a map while being routinely transited where the map goes quiet.
Many islands, more gaps than coverage
Building genuine coastal awareness across an archipelago means confronting a coverage problem that a mainland state does not face: dozens of inhabited islands, countless reef passages, and only so many emitting radar stations, each reaching to the horizon and each announcing exactly where its coverage begins and ends. The mid-water and the far edge of the zone stay effectively unwatched, and the maritime authority is left following a contact through the passages with a fragmented picture stitched from sites that cannot see the whole approach. Smuggling and unauthorised landings exploit precisely these seams between the islands.
Filling the seams without giving them away
Passive Radar is the natural gap-filler for a reef-strewn archipelago: exploiting ambient signals, it adds detection and tracking without emitting, extending 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 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 Fiji, retained under its control, with localisation arrangements scoped per programme and subject to export controls and end-use approvals.
How engagement works in Fiji
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 chain is weakest and a satellite baseline established over the wider approaches, revealing how current coverage is 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 an island coastline watched as a whole under national control.
Turning hundreds of shores into one picture
The engagement begins by briefing against Fiji's real coastal geometry: not one shore but hundreds, with more reef passages than any radar chain can hold and predictable gaps that unauthorised approaches learn to use. Before Unstrat represents the manufacturers, end-use is certified and export-control clearances confirmed, holding a single accountable channel. Capability is matched to the archipelago the operator actually watches: passive coverage placed in the seams without advertising itself or offering anything to jam, satellite tracking sized to the zone's edge, satellite fish-detection analytics for the inshore picture. Fielding is phased, targeting the weakest gaps first and revealing how coverage is being circumvented before it is made continuous, with in-region crews trained to run and sustain each layer. The advantage is an island coastline watched as a whole, following a contact from open water to the quayside, a mission that protects the approaches under national control. Localisation arrangements scoped per programme, subject to export controls and end-use approvals.

Adjacent priorities in Fiji
Fiji is a small state watching a large and valuable exclusive economic zone spread around hundreds of islands, where the tuna that anchors the economy draws distant-water fleets to the boundary. With few assets to cover so much open water, the fisheries authority sees only what comes ashore legally, and the true scale of what is taken stays invisible until stocks show the strain.
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 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.

Fiji: security context
Fiji's scattered islands shape its priorities: protection of a large exclusive economic zone and its fisheries, maritime domain awareness across dispersed waters, readiness for disaster response, and coastal surveillance. It is an environment where a small state watches over waters far larger than its land.
One accountable, non-aligned partner gives Fiji a coherent counterpart for those priorities: EEZ and fisheries protection, maritime domain awareness, disaster response and coastal surveillance. A security agency 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 do you cover the gaps between Fiji'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 reef passages between the islands without advertising where the new coverage is or offering anything for an adversary to jam.
How is Fiji's maritime picture extended beyond radar range?
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 scattered island coastline.
Is Fiji'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 Fiji 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.
