SeaVieweR Upgradeable AIS/GPS Receiver

SeaVieweR S.277 Dual AIS/GPS Receiver from SevenStar works with chart plotters and charting software for laptops and PDAs, and shows 'contacts' and their ID and course on the plotter display. You can see who else is within your vicinity, even if they are behind another object! (Headland, island, ship...)

·   The SeaVieweR receives AIS data on both AIS channels SIMULTANEOUSLY utilising 2 totally independent, synthesised VHF receivers and highly sophisticated digital signal processing. (Cheaper - and some more expensive - receivers only monitor one channel at a time – so with them you can miss vessel data altogether or at best take twice as long to receive it!)

·   Only one NMEA connection is needed for the AIS and GPS position data!

·   Also lets you see AIS nav aids (AtoN’s - Aids to Navigation) You won't see them without AIS!

·   And UNIQUELY, if you decide you want to get the full benefits of AIS, we can upgrade your SeaVieweR AIS/GPS receiver into a fully approved Class B AIS Transponder (See SeaTraceR section for features.) Your position and ID will then be transmitted to everyone around you so you appear on their displays! (Contact your local distributor for upgrade details.)

·   When upgraded, the resulting Class B transponder is fully approved to IEC 62287-1, IEC 60945, ITU-RM.1371-1, IEC 61162-1, IEC 61108-1, ITU R M.493-9, ITU R M.825-3, and certified by BABT, BSH, USCG & FCC.

·   AIS has been mandatory for SOLAS commercial and passenger vessels worldwide since 2004, and both our SeaVieweR receiver and our  SeaTraceR Class B AIS Transponder work within this system, bringing its wide-reaching benefits to the leisure and smaller commercial vessel market.

·   Robust and resilient to the stresses of life at sea, the units are housed in an IP-65 rated aluminium enclosure with versatile mounting hardware, all protected with a heavy-duty powder-coat finish.

Combined with a chart plotter or AIS-enabled radar set, AIS technology takes their performance into the next generation - once you've seen it in action, you won't believe you could have sailed without it!

What else do I need?...

All you need is a VHF antenna and a GPS antenna (active type) We are offering a very neat combined antenna. (see left) - and 12volt power of course, in order to receive AIS data from other vessels or navigation systems. To see the positions and identities of nearby vessels, use the supplied data cable to connect to your plotter,  nav station or lap-top PC (NMEA/RS422 and RS232 ports are provided).

How do I install it?...

The SeaVieweR AIS/GPS Receiver 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 should 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.). The transponder 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 unit can be wall-mounted, or suspended below or above working surfaces. It can be mounted permanently or removed when moored.

Easy to mount in any orientation!Waterproof to IP-65!
Full 16 channel DGPS Receiver!
Two Independent AIS receivers!
And uniquely UPGRADEABLE into a full   Class  B Transponder when you want to be seen..
