Breaking Boundaries In Subsea Imaging: How The ISS360 Series Is Redefining Compact Sonar
Impact Subsea, a leader in innovative subsea sensor technology, is proud to highlight the continuous development and global success of the ISS360 Imaging Sonar range.
Since its groundbreaking debut in 2020, the ISS360 has evolved into the industry’s premier solution for ROV and AUV navigation and target identification, offering a modern, high-performance replacement for legacy, scanning sonar systems.
A Five-Year Journey of Technical Excellence Launched in March 2020 as the world’s smallest scanning, imaging sonar, the ISS360 was designed to provide a step-change in capability for the underwater vehicle market.
The ISS360 Imaging Sonar has undergone development, evolving from the world’s most compact, scanning sonar into a high-definition powerhouse that outperforms systems many times its size.
Over the past five years, Impact Subsea has maintained a rigorous development roadmap to meet the increasing demands of the subsea industry:
• 2020: The Foundation: Introduced resilient operation via inductive coupling, entirely removing the need for slip rings, a common failure point in traditional scanning sonars.
• 2021: Extreme Depth: Launched the 6,000-meter rated ISS360, featuring a Titanium housing and specialized pressure-compensated components for ultra-deepwater missions.
•
2022: High-Definition Clarity: The launch of the ISS360HD brought a 1° acoustic angular resolution and a 2.5mm range resolution, enabling operators to identify targets in zero-visibility conditions with unprecedented detail.
• 2023: Seamless Integration: Direct GitHub access to an Open-Source Soſtware Development Kit (SDK), allowing AUV developers to integrate the sonar directly into bespoke soſtware packages.
• 2024: Released Impact Subsea Signalling Scheme (IS3): To reduce interference between sonars operating in close proximity to each other. This advanced signalling scheme makes use of CHIRP combined with Phase Shiſt modulation and coding.
• 2024: Released the ISP360: Expanding the sonar range with a profiling sonar option.
Seamless Integration: Open- Source SDK Impact Subsea believes in empowering users to push the boundaries of subsea autonomy. To facilitate this, the company provides a free, open-source Soſtware Development Kit (SDK) for direct integration. This operating-system- independent library, available via GitHub, has allowed AUV developers and manufacturers to integrate the ISS360 sonar directly into bespoke soſtware packages, enabling custom interfaces and advanced vehicle autonomy.
The Ideal Upgrade for Legacy Systems If your operations relied on recently discontinued compact scanning sonar lines, the ISS360 offers a
