New Delhi: Xalten Systems has signed an agreement with the Technology Development Board (TDB), under the Department of Science & Technology (DST), Government of India, for the project titled “Development of High-Performance Acoustic Antenna System for Underwater High Data Rate Communication for Video Transmission.”
The initiative marks a significant milestone for Xalten Systems in advancing indigenous underwater communication technologies.
The TDB-supported project will enable Xalten Systems to address a critical technology gap in underwater acoustic communication by developing next-generation hydrophone array sensor systems.
These systems are designed to support reliable, high-bandwidth communication – including real-time video transmission – between autonomous underwater platforms.
The initiative is being undertaken in collaboration with Subnero Pte Ltd, Singapore, combining Indian expertise in underwater acoustics with advanced software-defined communication systems.

With the increasing deployment of autonomous underwater vehicle (AUV) swarms for offshore energy operations, deep-sea exploration, marine research, and strategic applications, Xalten Systems is positioned to meet the urgent demand for robust, high-data-rate underwater communication systems.
Existing global solutions from established players such as Kongsberg Maritime, Sonardyne, and EvoLogics primarily focus on long-range, low-bandwidth communication built on legacy architectures.
In contrast, Xalten Systems aims to bridge this gap through the development of wideband hydrophones optimized for short-range, high-speed communication between multiple autonomous platforms.
The project envisions the design and development of an advanced acoustic antenna system capable of achieving megabit-per-second data rates while maintaining operational reliability in challenging underwater environments.
Through precision acoustic sensor arrays integrated with software-defined communication frameworks, Xalten Systems will enable real-time collaboration, navigation, and data sharing across marine robotic systems.
The initiative also seeks to establish scalable manufacturing capabilities within India for advanced acoustic sensors, thereby reducing reliance on imported technologies and strengthening domestic competence in underwater sensing and communication.
