Position-Tracking Polling Interval Sequence
Regulations allow transmission of one position-request call every five minutes. When tracking more than one
vessel, the radio alternates calling each vessel in the list at five-minute intervals. If a vessel does not respond to
five consecutive position-request calls, the radio removes the vessel from the position-tracking list.
You can use this table to better understand how the time interval is applied to the vessels in the position-
tracking list.
