Datasheet
SIPS 2 XSRS
Description
A key component in Sonardyne’s
SIPS System, XSRSs (Cross Streamer
Ranging System) are intelligent
acoustic devices used to measure
one way slant range distances
underwater.
Each receiver is capable of receiving
1 of 60 unique digital signals. The
use of digital acoustic signals and
digital processing techniques enable
the XSRS to transmit and receive
signals in the same event. In
addition, they are able to transmit
and receive SIPS 1 style tone burst
for cross wake ranges.
Key Features
•
Choice of Alkaline or Lithium
battery packs
•
Compatible with HGPS transceiver
•
Capable of receiving 16 ranges
per cycle
•
Designed to transmit to an
unlimited no of units
•
Flash upgradeable firmware
•
Sealed electronics compartment
The units are battery powered and
are mounted on the streamer sections
using industry standard collars. They
can also be mounted on tail buoys.
The XSRS units communicate with the
XSRS controllers by means of the
inductive coils and communication
circuit with in the streamers.
The Type 7885 XSRS units are
powered by individual standard C-
size alkaline or lithium cells. The
XSRS units have been designed to be
very energy efficient, with over 80%
of the available battery power being
transmitted into the water.
The design of the XSRS is based
around a proprietary application
specific integrated circuit (ASIC). The
ASIC enables the decoding of the
digital acoustic signal using digital
signal processing (DSP) techniques.
The unit has four receiver channels
and one transmit channel.
XSRSs are also available with a
direct reading sound speed sensor
(Type 8018 ASV XSRS). This ‘time of
Flight’ sensor provides superior
accuracy and ease of use compared
to the more traditional CTD methods,
particularly in areas affected by fresh
water and salt water mixing.
