AIS OPERATION

An AIS transponder can be connected to this radar to overlay AIS objects on the radar
display. The maximum number of AIS objects that can be stored in storage buffer of
this radar is shown in the following table. When this buffer becomes full of AIS objects,
an appropriate alert is generated to alert you to full storage buffer. The storage buffer
contains automatic dead reckoning for AIS targets (class A and B AIS targets and SAR
vessels) and AIS SAR aircrafts, which is based on reported Speed Over the Ground
(SOG), Course Over the Ground (COG), Rate Of Turn (ROT) and heading. The stor-
age buffer also contains calculation of range, bearing, CPA, TCPA, etc.
