All Implemented Interfaces:

CachedDecodedValues, Serializable

public class BinaryBroadcastMessage
extends AISMessage

broadcast message with unspecified binary payload. The St. Lawrence Seaway AIS system and the USG PAWSS system use this payload for local extension messages. It is variable in length up to a maximum of 1008 bits (up to 5 AIVDM sentence payloads).

Method Details

checkAISMessage

protected void checkAISMessage()

Description copied from class: AISMessage

This method performs a rudimentary sanity check of the AIS data payload contained in the NMEA sentence(s). These tests are mainly based on bitwise message length, even though other types of tests may occur.
