cNODE - Modem, embedable

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

A variety of flush mount and remote transducers are available, to provide optimal performance in shallow, deep water or horizontal modem and 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 modem with any HiPAP SSBL or cPAP LBL system.

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