Nasa Marine AIS radar
Anibody has already tested this unit?
"The Nasa Marine AIS radar is the first stand alone AIS receiver / plotter specifically designed for the leisure boat market. The display, with ranges of 1,2,4,8,16 and 32 nautical miles shows AIS carrying vessels in a format normally associated with conventional radar. A trail of previous positions clearly chows the relative track of all the targets on the screen. A box to the right of the screen displays the speed over the ground, the vessel name, mmsi number and the latidude and longitude of any target selected by the user. The compact unit has a white backlit LCD display, operates from 12 volts and consumes little power. The Nasa Marine AIS Radar is easy to use and will br available later this season at a RRP of =A3259." =20 Thanks by any coments=20 Pascal |

Thanks Dave, good thing this blog.
I found that Si-Tex sell the NASA AIS radar and the Nasa AIS Engine with theyr Logo Mark. And more, they newer Color Gps Chart Plotters (Gps with 18 chanels) supoorts the NASA (Si-tex) AIS Engine and displays the ships in the C-Map Color Charts, exactly what I would like to have in my Garmin GpsMap276C. They are the first leisure Chart Ploters to support AIS, I think, but probaly in the hig end price class. Regards Pascal |
Dave,
I am not shure, but I have the impression that You told that you have a Garmin GpsMap276C too, it is correct? Remenbering what that unknow guy told, that all the DSC ready garmin gpsploter already have support to AIS, and as You have a NASA or other AIS receiver, could You make a test to see if the Map276C can receives the AIVDM message? Pheraps it has the function to plot the ships position based on the AIVDM message, buried into the DSC function. What You think? Regards pascal |
Your panbo link is fantastic, I found this incredible software, wich
support AIS and the NASA engine, but is for Macs only, not for PCs. More incredible is the price: only US 50.00 ... Impressive list of features, like the MaxSea I could not believe. Pascal |

I doubt that it will work, and think that DSC is 9600 baud while AIS is 38400 baud, as well as using different protocols, but I may be able to check. My 276C is hard wired into my car at the moment, so I won't be checking for a while, but will try to remember next time I take the unit out for reloading of maps, etc. What "unknown" guys say doesn't usually give me much confidence - being an engineer I usually like to see some specs! :-) Dave The email address used for sending these postings is not valid.

Thank You Dave,
I know that this is improbable, but maybe garmin had put this covert function only for some selected guys to test it; the new release 3.20 included the setup NMEA speed (high speed/normal speed) but do not say what speed is... And if AIS and the NASA engine is having this fast and large aceptance, being selled by several others software and hardware makers, why not adopt it too, and make a litlle software/firmware modification to support it? And pheraps, sell it with garmin logo too, after a period of test? Best regards and thank you again. P.S. The link of the mac navigation software is: http://www.gpsnavx.com/ |

oups.com... Thank You Dave, I know that this is improbable, but maybe garmin had put this covert function only for some selected guys to test it; the new release 3.20 included the setup NMEA speed (high speed/normal speed) but do not say what speed is... NMEA high speed (HS) is 38400 baud. Meindert |
Than You Meindert,
How I can find if the "high speed" of 276C is 38400 or 9600? There is a way to test the 276C with a file containing records of AIVDM messages sended by an AIS receiver, and re-sending this messages to the serial port of the laptop, using a program like Windows Hyperteminal, so that the 276C woud read them again simulating a real AIS receiver? What the "unknown" guy said was: " Then I think you schould start reading again. All DCS capable Garmin receivers are also AIS capable. DCS is still the most wideley spread system, and AIS does not add anything to Garmin GPS receivers over the DCS system. You can easely combine a Garmin with DCS with a AIS reciever since the data send to the (external) gps is exactly the same" This made me suspect that he could have some confidential information about AIS and 276C and that the actual standard firmaware (3.20) maybe is already able to receive AIVDM messages and get ships's MMSI, name and position (at last), wich would be a proof that Garmin is already developing the software (and maybe some hardware) for AIS on some DSC ready gps receivers, like my 276C Regards Pascal |

You could indeed try that. This also allows you to test whether the garmin listens at 9600 or 38400 baud. Meindert |
Hi Meindert/Dave,
I tried this today. I get a big file with AIVDM messages from Ship Ploter site, and created a task on Hyperterminal and direct it to send to COM1 serial port, where is my 276C but I do not see anithing haping and I can not say if the messages was being sent to output COM1 port. I tried process the file with Ship Ploter, he accepts the file, read and process it, showing the messages and the ships list, but does not plot them in the map; I do not know if it was sending the messages in the NMEA out (same COM1 on the laptop where is pluged my 276C. I think that a real test with a real AIS receiver is a must to test this thing. I want to know if Garmin will support the AIS in order to make a decision on selling my 276C now and buy a Si-Tex chart ploter or wait for AIS on 276C. It is a dificult decision, since I am a Garmin customer for more than 10 yrs now, having had about 10 or more gps receivers from them. I know that there is other available solutions now, the AIS radar and the AIS engine from NASA with a PC software, are good alternatives, but my laptop consumes 4 Ah and my batery banks does not support this 24 hs a day. Sailing a boat at nigth in bad wether with a laptop in the desk and running the engine to charge the bateries is out of my mind. The AIS Radar is somewhat ugly and is not waterprof (humidity in a sail boat is always high) and does not have an NMEA output wich could be used in case I want to se the ships in the chart plot. I will thanks very much for any help here Regards Pascal |
