The Live is a digital multi-frequency acoustic receiver that spans 63kHz through 77kHz with precise millisecond timestamping allowing for fine scale positioning. It immediately relays acoustic detections to the surface using the robust and versatile industrial standard RS-485. The compact and rugged form factor of the receiver allows for installation in rough environments where space may be limited while also keeping the sensitive acoustic element protected. Live is designed with a strong emphasis on low power consumption such that it may operate directly on your field laptop or for months and years on small battery packs.
By utilizing an advanced digital signal processing unit, the receiver can offer maximum reception and flexibility. The processing algorithm dynamically adjusts to maintain high acoustic performance even in noisy environments. The digital signal processing along with a broad-range acoustic element enables the unit to be configured for operation at multiple frequency channels simultaneously. This greatly reduces the problem of signal collisions in densely populated settings. The algorithm also further reduces signal collision events by singling out the strongest when multiple signals are present. Live is hardware configured as a full transponder with the ability to receive and transmit acoustic communication signals.
