🎯 USBL Targets (tracked underwater objects)

*Position = each target's "home" relative to the main vessel's CRP, plus a small persistent random sway (so each target visibly moves independently instead of in a rigid pattern).

*The slot used by SSS/Mag Tow is set in the Vessel & Sensors tab > Main Vessel (dropdown "Linked to ...").

Column Hz = how often each sensor sends data (0 = sensor off, max 50). Orange/red = the estimated load exceeds the baud capacity (relevant for physical ports; virtual ports are not baud-limited).

⚠️ Fault Injection

Inject faults into the data being sent, to train operators or test how navigation software reacts. Sentences affected by a fault are marked orange in the log window. Set "Duration" so the fault switches off by itself.

▶️ NMEA Log Replay

Replay a real survey NMEA log file to one COM port. If the sentences carry timestamps (GGA/RMC/ZDA/GLL/...), the timing follows the timestamps. The target sensor's synthetic data is switched off during the replay; the map keeps using the simulation. Sentence-level faults (dropout, corrupt, loss, delay, GPS) also apply to the replay.

No file loaded.
