Data reporting intervals
AIS information is classed as either static or dynamic. Static
information is broadcast, when data has been amended, or upon
request, or by default, every 6 minutes.
The reporting rates for dynamic information depend on speed and
course change, and are given in the following tables.
Note: The reporting rates shown here are for reference and
may not be the rate at which information is actually received by
your AIS transceiver. This is dependent on a number of factors,
including but not limited to antenna height, gain and signal
interference.
