Information reporting intervals
The Nauticast
™-B AIS will transmit position reports (Message 18) in
reporting intervals of:
Every 30 seconds if SOG is > 2 kn;
Every 3 Minutes if SOG is < 2 kn
Provided that the transmission time periods are available. A command
received by Message 23 shall override the reporting interval.
static data sub messages 24A and 24B will be transmitted every 6 minutes
in addition to and independent of the position report.
