After the second delay period expires the target is no longer designated
as a TOI.
1. AIS targets
2. Radar targets
3. Intel targets
4. DSC targets
5. Received TOI
Note:
Received OneShot TOIs use the standard received TOI icons for the
duration of both delay periods and will then disappear.
TOI OneShot settings
TOI OneShot decay times and automatic repeat for sending / broadcasting
the related STEDS message can be adjusted.
TOI OneShot settings are accessed from the [Advanced set-up] menu:
[Homescreen > Settings > Responder > Advanced set-up > Configure] .
The following settings are available:
• [T1] — Number of seconds for the initial delay period.
• [T2] — Number of seconds for the second delay period.
TOI transmission rates
TOIs can be transmitted as either a single ‘OneShot’ transmission or as a
recurring transmission.
TOIs generated from Intel targets or DSC targets are automatically assigned
as OneShot TOIs. TOIs generated from AIS targets and Radar targets allow
the sender to select the TOI rate when the TOI is created. Recipients and
senders can change the TOI rate at anytime.
The following TOI rates can be selected:
• OneShot (Single Transmission) — TOI message is transmitted only once.
• Slow Target (600 sec repeat) — TOI message is transmitted every 600
seconds.
• Medium Target (180 sec repeat) — TOI message is transmitted every 180
seconds.
• Fast Target (60 sec repeat) — TOI message is transmitted every 60
seconds.
• Aircraft Target (15 sec repeat) — TOI message is transmitted every 15
seconds.
Note:
• A vessel can only send 1 recurring TOI message at a time. If a second
recurring TOI message is sent out it will replace the first TOI message.
• A vessel can send out multiple OneShot TOI messages.
• A vessel can receive multiple OneShot and recurring TOI messages.
• TOI rates for Intel targets and DSC targets are always set as OneShot
and cannot be changed.
TOI cancellation repeat
To ensure a TOI cancellation is received cancellations can be automatically
repeated multiple times at a specified interval.
The cancellation repeat options are accessed from the Responder menu tab:
[Homescreen > Settings > Responder > Advanced settings > Configure >
CANCEL/UPDATE MESSAGES]
. For following options are available:
• [Repeat] — Determines the number of times the TOI cancellation is
transmitted.
• [Interval] — Determines the time interval between sending cancellation
repeats..
TOI position updates
TOI positions are updated as follows:
• AIS targets and Radar targets will receive regular position updates from
the relevant device.
• Intel targets will maintain their initially reported heading and speed
• DSC targets remain static, unless position reports are received.
