Impact Subsea, a leading manufacturer of underwater sensors, has launched its newest sensor, the ISP360 Profiling Sonar, with IS³ acoustic signaling technology.

The ISP360 is a high-performance profiling sonar that sets a new standard in measurement precision and range capability.

A highly compact and power-efficient 1° profiling sonar, with up to 80 meters range and a 0.35 mm range accuracy. The ISP360 can be operated in profiling or imaging modes.

Acoustically, the ISP360 can operate over the frequency range of 600–1,250 kHz using Continuous Wave (CW), Compressed High Intensity Radar Pulse (CHIRP), or the Impact Subsea Signalling Standard (IS³).

IS³ signaling uses advanced phase modulation and coding techniques to provide the range resolution benefits of CHIRP but without the angular distortion inherent in CHIRP signaling. Critically, IS³ also allows multiple ISP360 profilers to operate at the same frequency with significantly reduced interference. This removes the requirement for ‘ping syncing,’ which is traditionally required for multiple mechanically scanned profilers, enabling much faster scanning capability when using multiple profilers and thus decreasing 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.”

The ISP360 offers a number of key features and benefits, including:

1° acoustic angular resolution
35 mm range accuracy
IS³ acoustic signaling for minimized noise between multiple profilers
Optional integration of pitch and roll for even more flexibility and control
Integration with seaView software for operation and data generation
Software Development Kit for direct integration into third-party systems

The ISP360 is perfect for a wide range of underwater applications, including:

Pipeline profiling
Trench profiling
Positioning of a vehicle in a tank
Internal pipe & tank profiling
Asset positioning
Bridge foundation survey

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