Positioning System (USBL)
A system similar to an SBL system except the system uses three or
more elements in a single transducer array. The measurements it
makes are the differences in “time-phase” of the signals from each
element. The co-ordinate frame is fixed to the transducer array which
must be oriented in the vessel frame to be equivalent to the SBL.
WSM Wideband Sub-Mini Transponder
Serial Communications
Wait
The maximum time allowed for the Transponder to reply to an RS232
command.
Delay between commands Provides a delay between adjacent commands.
ANT serial port Used for diagnostic checks.
Firmware
The firmware installed on the transponder. Firmware upgrades can
be installed via WSM Terminal. The Tx firmware refers to the
transmission signal synthesiser.
