Re: Class-B AIS and NMEA2000

Does anyone have comments on why:

"AIS Class B Transponder specification, all units must have a built-in GPS and cannot receive a position from other 3rd Party GPS units"

This just seems ludicrous to me.

I run a single GPS on N2k. If that GPS dies, I have (3) Icom radio screens blinking, (2) Furuno MFDs screaming like they were cut with a dull knife, the autopilot won't engage, basically all electronic navigation stops.

By meeting the specs, if the (additional) on-board GPS in the AIS dies, I won't know it unless I open the locker the unit is mounted in to see the led blinking.

In which case do you think the broken GPS would get fixed faster????

Hey Dotdun,

Check out your AIS manual... it will probably have extra ways of alerting you of GPS loosing lock.

Also, time for a 2nd GPS sensor in the network :-)

ciao!
Nick.

I don't want or need a 2nd GPS running, 4 spares that could be up and running with a couple of minutes.

This is a case of consumers having to live with the lobbying efforts of GPS chipset vendors. What a pain! It's just wrong!

The integrated gps idea in class B is ridiculous. Another camel that started as a horse.
