Sea4D for Defence and Security

Sea4D for assured maritime operations.

For naval surface fleets, USV operators, coastguards, port security and search and rescue. A sovereign UK capability, interoperable with NATO and allied forces.

The Scale
510%

increase in vessels affected by GPS jamming across 2025.

Windward, 2025.
The Problem Here
Conventional radar, cameras and AIS cannot provide them:
SEA STATE
Forecast rather than measured. Launch, recovery and small craft operations all wait on the call.
COLLISION RISK
Managed by visual and radar watchkeeping. Small, low and fast contacts are missed in sea clutter.
58%
of near-misses involve undetected targets
NorthStandard, 2024.
POSITION INTEGRITY
Reliant on continuous GNSS (GPS). Operations continue through jammed and spoofed waters.
13,000
vessels affected by GPS jamming in a single quarter of 2025
Windward.
The Answer
ALL-CONDITION DETECTION
Small, low and fast contacts held in sea clutter, in darkness and in fog, classified and logged.
GNSS-DENIED NAVIGATION
Position integrity maintained when GNSS is denied, and navigation continues.
MEASURED SEA STATE
The operational envelope from measured sea state at the point of work.

The contact picture, measured sea state and position integrity, logged and auditable, from one unit.
