1.2.1 Towfish
The towfish, which is shown in Figure 1-1, consists of a negatively buoyant
stainless steel housing with attached port and starboard side scan sonar
transducers, retractable port and starboard gap-filling transducers, a nose cone, and
a tail cone with stabilizing fins. The housing contains the sonar electronics, a
downlink demultiplexer for control signals and an uplink multiplexer for sonar and
sensor data. Internal sensors include a compass and motion sensor which provide
heading, pitch and roll; a pressure transducer which provides water pressure for
calculating depth; and a temperature sensor which provides water temperature.
The downlink control signals and the uplink sonar and sensor data are multiplexed
onto a single conductor coaxial tow cable. An electro-mechanical termination is
provided on the towfish end of the tow cable, where a shackle provides a strong,
reliable mechanical termination to the towfish tow bracket, and an underwater
connector connects to a jumper cable on the towfish. Four carrying handles, two
forward and two aft, are included for lifting and transporting the towfish, and a
safety cable tab is provided for connecting the safety cable to the tow cable.
1.2.2 Splashproof Transceiver and Processing Unit
(SP-III TPU)
The Splashproof Transceiver and Processing Unit (SP-III TPU) contains the
electronics for processing the sonar data and powering and communicating with
the towfish. The SP-III TPU is shown in Figure 1-2. The SP-III TPU is built into a
rugged, lightweight splashproof case and contains the electronics for powering the
towfish, downlink multiplexing the control signals to the towfish, uplink
demultiplexing the sonar and sensor data from the towfish, and communicating
with the laptop computer. The SP-III TPU also provides a navigation input. All of
the connectors, indicators and switches are splashproof and are located on a panel
on the side of the unit. The SP-III TPU is powered from either an AC or DC power
source.
CAUTION Do not submerge the SP-III TPU in water, as it is not designed
for continuous immersion.
