cNODE EXPLORER transponders are designed for integration onto AUVs, ROVs, landers or other vehicles where space and weight are restricted. The cNODE electronics can be supplied in a pressure rated underwater housing or in compact lightweight non pressure rated OEM housing for full third party integration.

cNODE® Explorer is a compact transponder fully compatible with HiPAP®, cPAP® and μPAP® underwater positioning systems. Both Low Frequency and Medium Frequency models are available.

cNODE® Explorer may be connected with up to three remote transducers. The transducers may be selected and switched electronically by the subsea vehicle control system or acoustically, to optimize for example vertical or horizontal telemetry and positioning performance.

The transponder will operate as any standard cNODE® offering telemetry, SSBL and long baseline positioning modes.

cNODE® Explorer interfaces to the subsea vehicle via a serial interface to transfer modem data. The transparent modem capability allows commands and data to be transmitted to and from the subsea vehicle from the customers topside AUV operator station, via the vessels HiPAP® system.
