The Easytrak System

Easytrak 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.

As a full system package, Easytrak has been specifically designed to overcome the difficulties of tracking underwater targets such as divers, ROV’s, AUV’s and tow-fish which operate out of sight beneath the water surface. As the name suggests, rapid deployment and ease of operation ensures that even novice users can commence tracking within minutes of set up.

The innovative, compact design incorporates an impressive amount of features, providing stable and accurate tracking for a variety of subsea tasks.

All Easytrak Systems Include

All operational equipment, hardware and software Integral pitch, roll and heading sensors to compensate for vessel movement GPS receiving software Robust, water resistant and lightweight enclosures Intuitive control software, bringing the confidence of professional USBL systems to a wide operator base

In Addition, Easytrak Can

Track multiple targets simultaneously Track horizontally, enabling the location of floating targets e.g. AUV retrieval Operate in diverse applications with universal appeal Negate the need for diver intervention in dangerous or contaminated waters Offer a versatility in system configuration that is second to none Operate AAE Acoustic Release Beacons

Four commercial versions of the system are available; the rack-mounted, vessel based Nexus; the Portable which includes a display screen and keyboard housed in a splash proof enclosure; the rack-mount Lite, which carries out the same functions as the Portable, and the smaller, compact Alpha.

The Nexus is the most recent model. In addition to tracking traditional ‘tone-burst’ beacons, it also tracks Spread Spectrum beacons which can offer increased performance.

In addition, a military Easytrak has been developed to operate inside the Operations room of a ship. The UK Royal Navy and other Navies around the world deploy this version.
