London Premiere for Applied Acoustics’ Vesta USBL
The latest incarnation of USBL from applied acoustics (aae technologies) makes its debut at Oceanology 2024, the biennial ocean technology showcase taking place at Excel, London’s leading exhibition and conference centre. Replacing the long serving but retiring Alpha systems and building upon aae’s expertise across the complete spectrum of subsea acoustic positioning, the new Vesta USBL has all the traits to become the workhorse of the entry level USBL market.
As with all USBLs, tracking performance determines the success or failure of these systems in terms of acceptance as a vital piece of the offshore armoury, and despite Vesta’s small format, it certainly packs a punch in this area. Featuring a smaller, lighter and more robust transceiver than its predecessor, the system can reach tracking ranges of up to 1km thanks to the introduction of aae’s new Sigma 3 digital spread spectrum acoustic protocols.
Surpassing the performance of the Alpha system, Sigma 3 also gives the ability for the Vesta system to track up to 8 targets simultaneously, to input an external heading reference, and to utilise the digital depth telemetry incorporated into aae’s range of depth beacon, which now includes depth capability built into the 1300 series micro beacon range.
Vesta USBL comprises an individual desktop console to which is connected the user’s operating PC and a 904C transceiver, an updated addition to the transceiver range featuring an integral AHRS, depth sensor and temperature sensor. With everything packaged in a single transit case the compact Vesta system is ideal for shipping between vessels of opportunity and small craft use.
The addition of Vesta USBL to the range of systems aae has to offer completes the portfolio of digital subsea tracking systems and widens the choice available to users, from entry level to extremely advanced with a number of options in between.
