AIS B Transponder
from SevenStar has
NOW BEEN UPGRADED TO FEATURE AN OUTSTANDING 50 CHANNEL GPS RECEIVER, USE
LESS POWER, AND ALSO HAS USB CONNECTIVITY FOR EASE OF USE.
Robust and resilient to the
stresses of life at sea, the
SeaTraceR is housed in an
IP-65 rated aluminium enclosure with matching and versatile mounting
hardware, all of which is protected with a sea-water resistant coating
under a heavy-duty powder-coat external finish.
POSSIBLY THE MOST ROBUST CLASS B
Combined with a chart plotter, laptop or
set, it takes
NAVIGATION SAFETY into the next generation - once you've seen
the SeaTraceR in
action, you won't believe you could have sailed without it!
- You can see who else is within
your vicinity, even if they
are behind another object!
(headland, island, ship...)
- You will be visible
to any AIS-equipped vessel or coast station within VHF range
- Two-way benefits are far superior to
dubious one-way performance of most radar reflectors
- You will see AIS navigation
beacons (AtoNs) clearly displayed on your screen
- Consistent and repeatable
performance, based on global standards
- Collisions can be more easily avoided
- Security monitoring at Ports,
- Hire and charter craft can be easily
- Anti-smuggling, Anti-piracy,
Anti-terrorist, Homeland security
How it works...
All you need is a VHF antenna, a
GPS antenna, and power of course, in order to transmit and
receive AIS data to and from other vessels or navigation systems.
We offer a very neat combined AIS/GPS antenna
that really simplifies installation. Our new SeaTraceR Combi2
antenna comes with 2 x 10 metre coax cables terminated with high quality
TNC connectors, ready to plug straight into the SeaTraceR unit.
the position and identities of nearby vessels, use the supplied data
cable to connect to your plotter, nav station or lap-top PC
(NMEA/RS422 and USB ports are provided). All recent plotters and chart
AIS data, and virtually all plotter manufacturers have upgrades available that will display AIS data. Also most radar
manufacturers are now well on route to overlaying AIS data on their
How and where do I install it...
SeaTraceR AIS B Transponder
needs connections to two antennas, namely VHF and GPS - these should be
placed in clear space away from other antennas, radomes, etc. (Note that
a GPS antenna need not be mounted high up a mast, due to the effects of
the boat 'heeling' on signal reception - best performance is usually obtained
around cabin roof height, mounted to the rail, etc.).
Our combined antenna (see right) is proving very popular for both leisure
and workboat use.
itself is ideally mounted in a sheltered position - although it is IP-65
protected, no box of
electronics likes to be continuously inundated with salt water,
rain, etc. The data and power connections go down to your normal nav
equipment, so the transponder can be fitted near that.
Rather than just meeting the
specification, we pride ourselves on designing user-friendly equipment,
and have designed the case and mounting brackets to suit many different
mounting requirements. Depending on your requirements, the transponder
unit can be wall-mounted, or suspended below or above working surfaces.
For professional applications we would recommend permanent fixing,
whereas leisure users may prefer the 'thumb-screw' style brackets for
easy removal of the unit when moored and left unattended.
Adding an AIS Transponder to your
vessel greatly improves your safety, security and situational awareness.
However, it does not totally replace the function of a good radar set, a
proven good radar reflector or a keen pair of eyes! There are some
circumstances when a commercial SOLAS vessel will still not see or react
to your transmission - but at least you will know he is there with AIS!
Nothing can take the place of good seamanship, good training, and good
