Easytrak AlphaEasytrak Alpha is the introductory and most compact version ofthe Applied Acoustics range of USBL tracking systems. Ideally suited for small subsea vehicle operations or basic diver tracking.Easytrak Alpha is a condensed and cost effective system for monitoring close range subsea targets.

Centered around the desktop command console, the innovative and carefully considered design allows Easytrak Alpha to be deployed in minutes, even by an inexperienced user. Connection to the host PCrunning Easytrak Alpha software is direct from the console via a USB port.

The system's lightweight transducer incorporates heading and tilt sensors and offers hemispherical trackingmaking it ideal for shallow water applications. The transducer cable is pre-moulded to the transducer,removing the need for a separate connector.

Easytrak Alpha has the additional advantage of its owninternal GPS receiver giving the system the ability tocalculate the target’s GPS position as well as its range and bearing.

Versatility of the system is further extended with thesupport of all AAE transponders and respondersthrough a number of pre-defined channels, With switchable interrogation rates completing the flexibility.
