At the heart of the system is the Nexus Command Console, a powerful 2U rack mounted processor with direct connection to the system’s Transceiver. Though the Transceiver has integral pitch, roll and heading sensors, serial ports on the Console allow the additional interface with external reference units for higher accuracy. Further ports connect to the display monitor, keyboard and mouse and to the ship’s Ethernet.
Like other Easytrak systems, Nexus works with a variety of underwater targets and beacon types including Responders, Release and Positioning Transponders, both in traditional ‘tone-burst’ and Spread Spectrum modes. These Spread Spectrum beacons include an enhanced 1000 Series with depth telemetry option and a bi-directional Spread Spectrum version for improved range stability.
The rack-mounted Nexus has a built in PC running embedded Windows XP with a solid state HD. The positioning information is displayed on a separate monitor where activity of up to ten subsea targets within a specified operating area can be viewed. These targets can be beacons operating on Easytrak traditional tone-burst channels, Easytrak Spread Spectrum channels or channels operating in the same frequency range from other sources.
