applied acoustics’ release beacons are ideal for deploying and recovering subsea equipment such as seabed instrumentation and environmental sensors, and can also be used as recoverable reference markers for positioning systems such as the Easytrak USBL range. Featuring low power consumption, the beacons transmit and receive signals to and from the surface, and can be commanded to release their anchor to allow the equipment and beacon to be recovered. They can also provide vital information such as tilt status and battery level.
The beacons utilize an FSK (frequency-shift keying) acoustic command protocol to ensure optimal performance in high-noise or reverberant conditions, and also feature positive drive-off mechanisms for reliable mechanical release in high bio-fouling environments.
