Referring back to my earlier posts on the Automatic Identification
System, I just got back from the UK and saw a very modestly priced unit
over there offered by NASA Marine Instruments. In fact they have two
versions. What they call their AIS Radar is a stand alone unit which
provides a high contrast backlit display screen of relative ship
positions with radar style rings and adjustable scales. About 6" x4".
This is an NMEA 0183 data stream. Clicking on any ship gives all the AIS
info and of course the targets leave a trail. UK cost retail about $390
ex-VAT. Their other unit is what they call an "engine" - a black box
using NMEA 2000 data stream which you can feed into your laptop plotting
program, or into a plotter that is NMEA 2000 compliant. Comes with
software. About $175 based on the UK price. Both units use regular VHF
antennas and appear to be dual channel 161.975 and 162.025 MHZ. The
competing Milltech Marine unit costs slightly more ($200) and is single
channel I believe. NASA is being handled by Sitex over here and they are
charging too much but will discount. Worth checking out.
