1. INTRODUCTION
The Imagenex Model 852-GS Ultra-Miniature Imaging Sonar was designed for use with the smallest of
R

O
perated
V
ehicles (ROVs) and inspection vehicles. Gyro-stabilization is integrated directly into the
sonar head, resulting in the sonar no longer being compromised by the blurring effects of host vehicle rotation.
The optional echo sounder is connected to the sonar, which, in turn, is connected to the surface. 2-Wire serial
communication is utilized (RS-485, or optionally RS-232, at 115.2 kbps). The unit will scan up to a 360° sector
with a maximum range of 50 meter
s. The sonar is controlled by a Windows™ based program that displays and
records data.
ROV information such as pitch, roll, and heading are available and the head can be operated using different
ranges, gains, pulse lengths, etc.
Note that although the 852-GS sonar may be ordered as an RS-232 option, the echo sounder may not be
interfaced via the 2-wire multi-drop system in this configuration.
