SeaKing & SeaPrince Imaging Sonars
0374-SOM-00001, Issue: 08 5 © Tritech International Ltd.
1. Introduction
The SeaKing and SeaPrince sonar "system" would consist of the sonar head, the Tritech
International Ltd Seanet Pro control and display software and either a Surface Control Unit
(SCU) or SeaHub. This manual deals with the sonar head and any specific aspects of Seanet
Pro that are necessary to get a system working. For more details of Seanet Pro please refer to
the Seanet Pro Software Manual and further details of the SeaHub or SCU can also be found
in their respective manuals (all current manuals are available on
www.moog.com/tritech).
The Seanet Pro software is Windows based and provides control of the complete range of
sonars that Tritech International Ltd produce. It is also possible to display multiple devices
within Seanet Pro and as such two or more sonars can be networked together and displayed
on one computer.
The SeaKing and SeaPrince sonar head is typically configured to communicate with the SCU
or SeaHub using the ARCNET LAN telemetry protocol. This is the standard protocol that is
used in all SeaKing devices and provides a high bandwidth at a default communications rate
of 156kbit·s
-1
. It is also possible to reconfigure sensors to communicate at a lower baud rate
or using serial protocols (such as RS232).
The DST SeaKing DFS & Super SeaPrince sonar heads have the following features:
Scan rate The heads can achieve a very fast scan rate which gives
faster target acquisition, and helps in obstacle avoidance.
Dual Frequency Operation
(SeaKing only)
The SeaKing DFS can use up to two operating
frequencies - one giving long range target acquisition
characteristics and the other giving shorter range, higher
definition, imaging capability. It is effectively two sonar
heads in a single housing.
Protected transducer The SeaKing has a semi-rigid rubber boot and the
SeaPrince units have a rigid plastic boot, both are oil filled
and offer protection of the transducer head. The unit has
no rotating seals to be damaged or wear.
Electrical Connection The SeaKing and SeaPrince heads use a Tritech
International Ltd 6 pin underwater connector but can be
fitted with an alternative connector on request.
