New Small-form Subsea Positioning Transponders

Following on from the end of 2015 launch of its new generation underwater positioning system, HiPAP 502, Kongsberg Maritime is introducing a new range of mini medium frequency subsea transponders. With a smaller form factor, improved operational functionality and design, and the use of modern materials the new cNODE MiniS family supersedes the KONGSBERG Mini SSBL transponders (MST) range, which was first available in 2002.

Expanding the cNODE portfolio, the cNODE MiniS 34-180 and cNODE MiniS 34-40V are the smallest transponders for use with HiPAP, cPAP and µPAP underwater positioning systems, and are suited for accurate Remotely Operated Vehicle (ROV) positioning operations. Both new cNODE MiniS transponders are depth rated to 4,000 m and offer a diverse range of applications.

cNODE MiniS 34-180 and cNODE MiniS 34-40V operate on HiPAP/HPR 400 channels with over 500 Cymbal channels. The advanced Cymbal protocol transmits more energy into the water, which together with uniqueness coding, new filtering and processing techniques, offers a number of benefits including better angular accuracy, improved range specification, higher position update and telemetry rate and longer endurance between battery charges.

Compatible with SSBL and LBL positioning configurations, other technical features of the new cNODE MiniS family of underwater transponders include an internal rechargeable Li-Ion battery that can be charged from empty to 100 percent in under an hour and the ability to charge from a ROV’s onboard 24v supply. Also included is an advanced internal tilt sensor working up to ±90°, which can alert operators should the transponder lose optimal positioning on the seabed.
