Nexus Lite


 
General 
Product Name:Nexus Lite
Product Description:Nexus Lite is an Ultra Short Baseline (USBL) underwater positioning and tracking system centred on a multi-element, single transducer that transmits and receives acoustic signals to dynamic subsea targets from which range, bearing and depth information can be determined. It incorporates Sigma 1 Spread Spectrum technology to provide a secure acoustic link. By incorporating Sigma 1 technology the wide bandwidth transmissions reduce the system's susceptibility to interference. Designed for ease of installation in a vessel's operations room, the surface console has been mounted within a rugged 1U enclosure for connection to a laptop or tablet PC.
