Overview

Power, comms and timing for Mini-Ranger 2

The Ethernet Serial Hub (ESH) is designed for small survey vessel operations using Mini-Ranger 2 USBL to track multiple subsea targets. Engineered for vessels, ESH is suitable for environmental surveys, coastal science and sensor tracking as well as site surveys and characterisation.

Overview

The ESH is the network interface between the in-water acoustic instrument, GPS and the PC that runs the positioning software.

In addition to accurately time-stamping incoming data from external devices such as gyro, VRU and GPS it provides power and communications for acoustic transceivers.

The ESH includes a time source that can be linked to an internal or external GPS PPS input, allowing the Ranger 2 system to accurately time-stamp incoming data from external devices such as gyro, VRU and GNSS to UTC.

Wi-Fi connectivity allows connection to a PC using a Wi-Fi adapter.
