[ gpsdrive ] Miles per hour

[Doug Robinson]

AIS traffic comes from a radio receiver via a serial link most generally.
 Could be integrated using a Bluetooth stream as well.  As I understand it
class A traffic (the big ships), transmit position twice a minute and
generally are moving @ 5 to 25 knots.  Class B traffic (us little guys), are
transmitting once a minute and could be at 6 knots for the rag driven and
35+ knots for the stink pots.  Guess I would recast the incoming traffic
from AIS into the existing GPSDrive format as data off the friends server
and have a look.  US govt has finally adopted the Class B standard (better
late than never) and receivers are on the market from $189 and up.To see a
display of the results look here:
