Impact Subsea unveils ISP360 sonar for precision underwater mapping

Impact Subsea, a recognized manufacturer of underwater sensors, has announced the launch of its ISP360 Profiling Sonar, incorporating IS³ acoustic signaling technology. Designed to enhance underwater measurement and imaging, the ISP360 delivers a high standard of precision and range.

The sonar is compact and energy-efficient, offering a 1° profiling beam with a range of up to 80 metres and a range accuracy of 0.35mm. It operates in both profiling and imaging modes, supporting acoustic frequencies from 600kHz to 1,250kHz. The ISP360 utilizes continuous wave (CW), compressed high-intensity radar pulse (CHIRP) and Impact Subsea’s proprietary IS³ signaling standards.

Advanced phase modulation

A notable feature of IS³ signaling is its use of advanced phase modulation and coding techniques, which provide the range resolution of CHIRP while avoiding angular distortion. Additionally, IS³ enables multiple ISP360 units to operate simultaneously at the same frequency with minimal interference, eliminating the need for traditional ‘ping syncing’. This improvement allows faster scanning with multiple profilers, contributing to reduced survey times.

“We are excited to introduce the ISP360 Profiling Sonar to the market,” said Ben Grant, managing director of Impact Subsea. “The ISP360 is a game-changer for underwater profiling and positioning. With integrated IS³ signaling technology coupled with a highly sensitive broadband composite transducer, the ISP360 delivers unparalleled accuracy for sonar profiling with optional pitch and roll, all from a single device.”

He added: “The ISP360 is a valuable asset for anyone who needs to collect accurate and detailed data about the underwater environment. With its advanced features and versatility, we are confident that the ISP360 will quickly become the industry standard for mechanically scanned sonar profiling.”
