Subsonus Datasheet

Product catalog summary

Overview
Subsonus is a compact underwater acoustic positioning system offering high accuracy in position, velocity, and heading up to 1000 meters. It functions reliably in challenging acoustic environments due to advanced signal processing and a unique hydrophone design. Additionally, it operates as an underwater data modem.

Performance and Applications
Key features include integrated INS, multipath rejection, acoustic modem capabilities, and low size, weight, and power requirements. It provides 0.1 m positioning accuracy, 0.1° roll and pitch, 0.3° acoustic heading, and operates at depths and ranges up to 1000 meters. Applications include diver tracking, subsea surveying, and AUV & ROV navigation.

Features
Subsonus dynamically adjusts acoustic transmit power and signal encoding for improved performance. It features an eight-channel hydrophone array for beamforming and multipath rejection. The system transfers high accuracy GNSS heading underwater without a gyrocompass, avoiding magnetic interference. It is self-contained, requiring no external equipment, and connects via a single ethernet connection with a web-based interface.

Specifications
Subsonus integrates GNSS/INS with a GNSS antenna atop the hydrophone array. It has a pressure sensor range of 1000 m with 1.5 m accuracy. Position accuracy varies from 0.1 m at 5 m range to 5.0 m at 1000 m range. Other specifications include 0.01 m/s velocity accuracy, 0.1° roll and pitch accuracy, 0.3° heading accuracy, and 5% or 0.05 m heave accuracy. It supports PTP and NTP timing synchronization, operates between -20°C to 40°C, and has a shock limit of 25 g.

Hardware and Acoustics
The system includes eight hydrophones operating at 30 kHz frequency with a 1000 m range and 300° hemispherical acoustic coverage. It offers 0.1% range accuracy and 0.1° angular accuracy with an update rate up to 10 Hz.

Contact Information
Advanced Navigation has offices in Europe, North America, and Australia, providing contact details for sales and support.
