NSH is a 2U high rack-mounted unit that is the interface between your in-water deployed transponders, vessel-mounted transceiver and Marine Computer which runs Ranger 2 USBL or Marksman LUSBL software applications.

In addition to accurately time-stamping incoming data from external devices such as gyro, VRU and GNSS, the NSH also provides power and communications for ship-borne acoustic transceivers; HPT 5000 or HPT 7000.

A range of hardware interface cards are available for interfacing Sonardyne transceivers and external sensors. By simply plugging these cards into the rear of the unit, the role of the Navigation Sensor Hub can be transformed from supporting simple to complex acoustic operations.

The NSH includes an IEEE-1588/PTP precision time source that can be linked to GPS PPS input. Multiple NSHs automatically synchronise their clocks. All incoming data is time stamped to sub-microsecond accuracy; outgoing transmissions and triggers can be scheduled to the same precision.

Depending on the application (DP, drilling or survey operations), the NSH can be configured in stand-alone, dual-independent or dual-redundant modes.
