Kongsberg MST 342 Mini SSBL Transponder – Available for rental, hire and ex-rental purchase from Ashtead Technology.
The Kongsberg Mini SSBL transponders (MST) are medium frequency mini-transponders. They are designed to be used with the the HiPAP system and HPR series underwater positioning and navigation systems. Ideal for applications where a small and lightweight unit is required. The MST transponder is delivered with a moulded protective plastic coating with all switches and connectors recessed within the end cap for added protection and the transponder comes with a pigtail with connector. The MST 342 operates in the 30kHz band, depth rated to 4000 metres, with a ±20° beamwidth.
The design makes extensive use of surface mount technology. This allows all of the hardware to be confined to two boards, thus increasing reliability and reducing spare part holding requirements. The unit is designed with a modular construction. The electronics, battery pack, transducer and end cap can easily be replaced individually.
