Portable Gps/Plotter with AIS-Receiver Support
Anybody knows one? I am using a non portable solution: SR161 + Laptop
+ GpsMap 276C. I would like to have a gps/plotter portable (or handheld), WeatherProof and useable in the cockpit. I have asked Garmin to give the AIS receiver supprt on the GpsMap 276C but after waiting 2 years I have quit. Thanks Pascal |

Why don't you buy two serial to blue tooth adapters (cable replacement) from
Aircable, set them to 38400 baud for transmission of AIS data to your chart plotter. Keep your AIS receiver with VHF antenna connection inside and chart plotter in cockpit. The small bt-module is easy to water-proof for use in the cockpit. plano "Pascal" wrote in message ups.com... Anybody knows one? I am using a non portable solution: SR161 + Laptop + GpsMap 276C.

Thank You for the good idea, I have made a look in the AirCable site
and seems a good way to eliminate cables, but prior to use this, I must have an AIS enabled Gps/plotter, which is what I am looking for at the moment. Regards Pascal |

Portable Gps/Plotter with AIS-Receiver Support
Ok, but as I have said, I want a "Portable" unit.. I know that there
are many models of gps/ploters that are AIS enabled, like those more recent units from Garmin, Navman, Raymarine, etc but none of them are "portable" (that is, battery operated and easily removable to be used in another boat and at home). Of course, the ideal for me would be a portable or handheld unit wicth would be a combined "Gps-Plotter-AISReceiver" all in one, but in lack of integrated AIS, the unit could be at last AIS Ready, using a external AIS Receiver, preferentially, with integrated Bluetooth. The classical "Nasa AIS Radar" was a very good idea, since in reality, we really do not need a chartplotter, but it is not portable and not weather proof to be used in the cockpit. Thanks Pascal |

@q2g2000cwa.googlegroups.com: I know that there are many models of gps/ploters that are AIS enabled, That all sounds good until you look at what comes out of the AIS at 38,800 baud RS-232 level data....then look at the GPS/Plotters plodding along on RS-422 (NMEA-0183 isn't RS-232C compatible) at 4800 baud..... Wrong baud rate, wrong voltage levels, INCOMPATIBLE AS USUAL.... "AIS Enabled" just means they'll read an AIS statement IF IT COMES IN AT NMEA'S slow baud rate with the rest of the NMEA data. You can't just plug them in, of course. On Lionheart, our current configuration is an SR-161 receiver feeding a Radio Shack RS-232C serial to USB interface cable ($10) plugged into a USB port on the Dell Latitude notebook running the accompanying virtual serial port software so The Cap'n nav software can find the 38,800 baud data stream on what it thinks is a serial port. NMEA system data comes in on another virtual serial port from my wireless router on the NMEA system. The Cap'n regurgitates the AIS data statements at 4800 baud to the NMEA system so it will show up on any instruments capable of reading it. SOME, not all, models of Raymarine and Garmin are capable of reading it from the NMEA stream IF you upgrade their firmware or buy something new. Currently, seeing the ships on the computer display chart is fine...(c; I want to add another Webfoot RS-232C to Ethernet adapter to our Wireless system. When I get that installed, I'm going to feed it the AIS data from the SR-161 receiver. Being on a separate hard-wired Ethernet address on our LAN, I'll be able to connect to its LAN IP address with the second virtual serial port driver that comes with the Webfoot and can eliminate the current Radio Shack hard-wired USB connection AIS is attached to......making both NMEA at 4800 baud and AIS at 38,800 baud available to The Cap'n WIRELESSLY so it will run anywhere on the boat...or even at the yacht club bar if we dock the boat at the club...

Portable Gps/Plotter with AIS-Receiver Support
Does it make sense ??
It's hard enough already to read the disply on portable units. Adding AIS data on top will just make it totally unreadable. You might be able to read at home, in good light and with you glasses on, but in the boat, dark, raining and in a "windy and critical" situation, you wouldn't be able to see anything ....

Well Bjarke, I have seen the AIS data on a Garmin GpsMap 3205 and I reputed the 5" size very good. Course that the display of targets on a RayMarine C80 I had seen too, is better. All wil depend on the zoom level you set the unit, and I think that in regions with no very heavy traffic like here, if it will show about 10 targets at the 5 nm range, this will be very visible. Anyway, in a critical situation, I could reduce the chart detail on the plotter (declutter) and the best thing will be to hear the alarm and see the ship name, course, speed etc. I have used Ais in my Notebook with SeaClear and ShipPlotter and it is fine, the problem is the size of the laptop, the current drain, the mess of cables etc. And what I want is to have all this information at the helm, not below at the nav table.

: Does it make sense ?? None of the receivers make any sense, actually. They don't tell "THEM", up there on the bridge 200' above the sea and 150' above your mast, that you are THERE and going THIS WAY. No alarms go off as they STILL CAN'T SEE YOU! So, none of these receivers make any sense. What DOES make sense is for a boat TRANSPONDER to make YOU a target on THEIR plotter to be reckoned with. You would set off the alarm long before you were pushed under the bow waves and into the screws. He wouldn't have to try to "see" you down below the level of the containers piled high on the deck in front of him for 950 feet. He could "see" you, who you are, WHAT YOUR BOAT NAME AND CALLSIGN IS, where you're headed, your course and speed, right on his automatic plotting board. Armed with this information, he'd CALL YOU on VHF to warn you to get the hell out of his way. Until we bleed all the big yachts for thousands and thousands of dollars http://store.milltechmarine.com/acrglaistr.html and allow the Chinese electronics companies to send TRANSPONDERS to the yachtie countries, like the USA and Danmark, that don't cost any more than any other overpriced VHF radio at some marine electronics shop.....you won't be a target on his plotter and be on your own. Pity..... Larry -- http://stinet.dtic.mil/cgi-bin/GetTR...61&Location=U2 &doc=GetTRDoc.pdf |
