1-6 1.0: OVERVIEW
2000-DSS COMBINED SONAR 0009335_REV_D
NOTE: The option connector provides 27 VDC @ 1 A maximum.
1.3.1 Magnetometer
A magnetometer can be user specified or supplied and is available from a number of manufacturers.
1.3.2 Acoustic Tracking System
An acoustic tracking system, such as an ORE BATS or Trackpoint 3, can be used to continuously provide
tow vehicle position. A responder is installed on the tow vehicle and a ship mounted hydrophone and
deck unit are used to receive and process position data.
1.3.3 Pressure Sensor
A pressure sensor can be installed in the tow vehicle to provide tow vehicle depth data. This type of
pressure sensor is designed for continuous use in a corrosive liquid environment and has a 3000-psi
pressure range.
1.3.4 Power Loss Pinger
A power loss pinger activates when tow vehicle power is lost and the tow vehicle is submerged. Should
this event occur, the pinger will continuously transmit an acoustic pulse which can be received by a pinger
locator. The pinger is fully self-contained in a stainless steel or aluminum housing and includes an internal
battery.
1.3.5 Responder
The responder functions with an optional acoustic tracking system to provide tow vehicle positioning. The
tracking system deck unit provides a trigger which is input to the 2000 Topside Processor, and the 2000
Topside Processor outputs the trigger signal to the tow vehicle by combining the signal with the downlink
command and uplink sonar data signals.
1.4 Full Spectrum Chirp Technology Overview
EdgeTech's Full Spectrum Chirp technology has several distinct advantages over conventional side scan
and sub-bottom profiling systems. These benefits include the use of separate sub-bottom acoustic
projectors and receivers to enable simultaneous transmission and reception of acoustic signals, high
signal-to-noise ratio (SNR) for improved side scan and sub-bottom imagery, high repeatability of the
transmitted signals from pulse to pulse for high signal definition, high resolution for measurement of fine
