BATS AND PORTABLE BATS OPERATION
3-24
 Depth Tab
The Depth Tab configures
the target depth function.
Select the Mode in which the
depth is input from; Teleme-
try, Analog, Serial Port (PC),
Manual. If the Beacon is a
(time-proportional) Depth
Telemetry version then se-
lect “Telemetry“ and then
under “Depth Mode Setup”
configure the Beacon’s Te-
lemetry parameters. If depth
is via an analog sensor, e.g.,
an ROV or SSS vehicle, then
select “Analog” and then un-
der “Depth Mode Setup” con-
figure the Beacon’s Analog
parameters. The analog port is available at the GYRO connector on the rear panel of the BATS
Desktop or the side panel of the Portable unit. If the target’s depth is available via a serial port,
select “Serial Port” and then under “Depth Mode Setup” configure the Beacon’s Comport parame-
ters. Select the Depth Input sentence, DBS, DBT, PEIV1 or DPT. (See formats below.) This Serial
port is available only at the PC’s serial input not
the Transceiver’s.

In the TELEMETRY mode the depth is taken from
a depth telemetering transponder. The tran-
sponder sends two replies to the Transceiver per
interrogation. The first reply signal is used to
determine slant range and bearing, while the se-
cond reply (whose delay from the first is propor-
tional to depth) is used in the depth calculation.
Given these three parameters a three-
dimensional position fix is calculated. The “Te-
lemetry Depth Setup” menu is used in conjunc-
tion with “Telemetry Mode”. It contains parameters to allow the operator to change the telemetry

If the entered depth is not correct the calculated horizontal range will also be incorrect.
