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.
