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
