- Internal rechargeable battery
- Installed in Wave Glider standard aft payload space
More about this product
Wave Glider Transceiver Overview
The WGT functionality enables Wave Glider to acoustically collect data from large arrays of seabed instruments in a highly cost effective manner without the need to deploy a traditional surface ship to perform this operation. Instead, Wave Glider is controlled remotely from a shore station via Iridium satellite communications.
The WGT is available with directional transducer options for operating in both Medium Frequency (19-34kHz) and Lower Medium Frequency (12-20kHz) bands to suit different seabed instruments and is fully Sonardyne Wideband® 2 compatible.
The WGT is tightly integrated into the Wave Glider vehicle communications and power systems thereby providing many of the standard acoustic commands and features associated with Sonardyne 6G products.
Data are passed by Wave Glider to the Iridium satellite system for on-wards transmission to the user in near real time.

*TEE – WBv2+ signals are 4x the duration (WBv1 & WBv2 are twice) of Sonardyne tone signals, therefore the TEE figure is to give the user an idea of the operational performance when comparing Wideband and Tone systems.
