Compact Dome and Open-Array Antennas

In darkness and fog, busy channels and treacherous weather, situational awareness is the name of the game. Whether you want a pure, clear radar presentation or a chart display with radar overlay and target tracking, Geonav^® HD Ethernet Radar delivers. You’ll be able to define vessels, obstacles and structures with pin-point precision and in stunning High Definition. Unleash 4kW of power with your choice of compact dome or open-array antenna configurations, all featuring zero-latency Ethernet broadband.

ENHANCED TARGET DISCRIMINATION

Ensure accurate target detection at both long- and short-range scales with proven 4kW transmitter and ultra-sensitive low-noise receiver.

20-TARGET MARPA TRACKING

Acquire and track vital information (bearing, range, speed, course, CPA and TCPA) of up to 20 targets at once—with notification of unsafe targets.

DUAL VRM/EBL

Create up to two Variable Range Markers (VRM) and two Electronic Bearing Lines (EBL) for easy range and bearing measurements.

ZERO-LATENCY ETHERNET

Enjoy precise, real-time target location, even during rapid manoeuvers and in rough seas.

ECHO TRAIL TRACKING

Visually track the recent relative movement of radar targets.

AUTOMATIC GAIN/SEA CLUTTER CONTROL

See only what you need to with this dynamic filter that automatically or manually eliminates screen clutter caused by rain and sea returns.

DUAL GUARD ZONES

Establish up to two guard zones (sector or circular) and monitor any radar target within each zone.

SECTOR BLANKING

Disable radar transmission over a defined arc to avoid the flybridge area or reduce reflections from fixed objects on your boat.

TRUE PALETTE

View the relative density of targets in eight different colours using this presentation option.
