2.3 Transmission intervals
The transmission intervals are normally as described in Table 1: Transmission intervals. Given certain
conditions, as in assigned mode, or when other AIS stations are synchronizing to the unit, the
transmission rate might be higher, but the absolute highest rate is once every 2 seconds.
