Super SeaKing DST
Dual Frequency Digital CHIRP Sonar
Advanced CHIRP signal processing for clear and high resolution imagery The Super SeaKing DST is a digital CHIRP dual frequency sonar capable of operating at 325kHz or 675kHz. When operating at 325kHz the sonar has a true operational range of 300m. Switching to 675kHz, the same sensor is capable of providing a high definition image at shorter range.
The very latest in composite transducer and CHIRP technology has been used to
produce the advanced Super SeaKing Dual Frequency CHIRP Sonar. It delivers the clearest images available, at operating ranges previously unobtainable.
CHIRP technology dramatically improves the range resolution compared with conventional sonars. Resolution can be improved by a factor of five times.
The Super SeaKing DST shares many of the features of the earlier SeaKing, which has been chosen as the standard obstacle avoidance sonar in many of the professional ROV fleets around the world. In addition, a modular transducer design and longer life slip ring assembly have been introduced to minimise the consequences of operational damage and to further improve upon the SeaKing’s already excellent reliability.

USBL tracking for small vehicles
The MicronNav system is an innovative Ultra- Short Base Line (USBL) positioning system designed for small vehicles. It has been primarily designed to be used in conjunction with the Tritech Micron sonar and other products in the Micron range but will also adapt well to other sonars such as those from the SeaKing range.
The system comprises a subsea MicronNav Transponder/Responder, a surface USBL transducer with integral magnetic compass and pitch/roll sensors, a surface MicronNav 100 interface hub and operating software under control of a host PC/laptop. The MicronNav uses the very latest in spread spectrum acoustic technology.
This provides a robust method for communication between the dunking transducers and the vehicle responder/ transponder. The USBL transducer can provide 180 degree hemispherical coverage below the transducer, which allows vehicle tracking in very shallow water. Omni directional coverage is provided by the MicronNav ROV Transponder/Responder. The MicronNav “Transponder” is a stand-alone device which responds to acoustic interrogation from the USBL head. The MicronNav “Responder” is powered and interrogated by the MicronNav through the auxiliary port on the Tritech Micron sonar (either RS232 or RS485).
