ACOUSTIC RELEASE BEACONS AND POSITIONING BEACONS

Acoustic release beacons

Acoustic release beacons are used to recover or lower equipment deployed under the sea, either in shallow or continental shelf waters. 

applied acoustics supplies standard products and customised versions of release beacons to meet specific underwater release, command or control requirements.

Features

Positive drive-off mechanisms ensure reliable mechanical release in high bio-fouling environments

Reliable FSK acoustic command protocol for communications security in high noise/ reverberant environments

Safe working load (SWL) includes 4x factor of safety

Field-adjustable internal frequency and release identities

Command and configured by 3510 PAM Portable and Easytrak Pyxis, Nexus and Nexus Lite

Also operates as standard acoustic positioning beacon with Easytrak USBL range and other industry standard systems 

Applications

Long-term environmental and met-ocean observations

Equipment recovery

Seabed markers and instrument deployment

Deploy or place objects onto the sea floor 

USBL calibration

Positioning Beacons

applied acoustics’ range of acoustic positioning beacons is one of the most extensive available from any manufacturer and includes micro beacons, for use in shallow water or where space is limited, up to the seabed beacons operating in deep, noisy or difficult environments. 

Features

Robust, rugged construction

Easy selection of transmit and receive frequencies

High reputation for signal stability

Rigorously tested for distinguished endurance and performance

Compatible with almost all industry-standard tracking systems

Applications

Micro Beacons – Ideal for divers, short ranges and small ROV tracking

Mini Beacons – ‘Work-horse’ beacons for towfish and ROV tracking, and often used by divers. Also provide navigation and data for monitoring third-party sensors 

Midi Beacons –  High powered but compact. Used for long-range towfish tracking and AUV positioning

Fatboy Beacons – General purpose tracking and positioning of static and dynamic assets, e.g. AUV, sidescan sonar, in deeper water or challenging environments  

Low Frequency Beacons – Long-range, deep-water applications 

Seabed Beacons – Large battery capacity for long-term deployment; often used as reference markers
