Thanks Dave, but them I would ask You: and the NASA stand alone
"radar", or the NASA "engine"; can it support the AIS trafic? Do you
think it has a much faster processor then the 276C?

Well, it's (NASA radar) got a crappier display, with no colour & no maps, so
it doesn't have anything else to do except decode & display boat positions.
However, the 276C is already pretty busy with it's large/huge colour maps to
be processed, GPS to be taken care of, etc. From my use of the 276C for the
past year(?) & extensive use & programming of AIS systems, I'd say the 276C
doesn't have enough processor power left to handle any serious AIS
requirement.

NASA engine only has to decode & output AIS via serial output, so it doesn't
need to be that fast - it's only a single task.

Hi Dave,

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.
