The cNODE Embed electronics, together with a transducer and external power, functions as a transponder. Designed for integration into custom subsea housings the transponder is fully compatible with HiPAP, cPAP and μPAP positioning systems.

Transducer
Titanium transducer TD80V Low.

The cNODE Embed provides flexibility to integrate KONGSBERG transponder electronics into a custom pressure housing. This provides advantages to reduce size, weight and the need for interface cabling.

A variety of flush mount and remote transducers are available, to provide optimal performance in shallow, deep water or horizontal positioning applications for AUVs, ROVs, gliders, towed fish or nodes.

The same SSBL, LBL and telemetry capability is featured on the board as per a standard cNODE providing the same performance when positioning the transponder with any HiPAP SSBL or cPAP LBL system.

Operating in the Medium Frequency 20khz to 30Khz band, both FSK and KONGSBERG Cymbal navigation codes are available. Cymbal wideband offers 560 unique navigation codes and range accuracies of better than 2cm, are achievable.
