Applied Acoustics products

The comparison between traditional USBL systems and closely coupled INS + USBL solutions highlights significant technological advancements in underwater acoustic positioning. Applied Acoustics has leveraged its expertise to enhance the accuracy and efficiency of these systems. The traditional USBL systems, known for their ease of deployment, are capable of dynamic subsea target positioning via acoustic signal transmission and reception. However, the closely coupled INS + USBL solution integrates an inertial navigation system (INS), providing superior position accuracy even in challenging acoustic environments with high noise levels or a limited line of sight. This synergy between USBL and INS ensures more reliable and precise tracking essential for complex marine operations, such as drilling and construction. The innovation in signal processing with advanced acoustic protocols improves data integrity and minimizes errors, making these systems critical for extended underwater missions.

The Easytrak Nexus 2, Model 2692, is an advanced digital Ultra-Short BaseLine (USBL) system designed for precise positioning and tracking in marine environments. This second-generation system is engineered for quick deployment and ease of operation, making it ideal for various underwater applications. It employs aae Sigma 2 acoustic protocols, ensuring a robust acoustic link through digital spread spectrum transmissions that offer high security and minimal interference. This enables the system to deliver highly accurate and reliable positioning data over extended operational ranges. Nexus 2 is particularly beneficial for professionals requiring dependable underwater tracking solutions, offering enhanced performance in challenging conditions. Whether for scientific research, offshore construction, or defense applications, the system provides a critical edge in underwater positioning technology.
