High Performance Profiling Sonar
ISP360 Profiling Sonar 

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 0.35mm timing resolution.  The ISP360 provides sonar imagery with profiler points overlaid on top of this.  Each point can then be logged or output to a survey package to enable the creation of a 3D points cloud.

Acoustically the ISP360 can operate over the frequency range of 650kHz to 1.25MHz using Continuous Wave (CW), Compressed High Intensity Radar Pulse (CHIRP) or the Impact Subsea Signalling Scheme (IS3).

IS3 Impact Subsea Signalling Scheme uses advanced phase modulation and coding techniques to provide exceptional signal integrity, timing accuracy and range resolution. IS3 provides the range resolution benefits of CHIRP acoustics but without the angular distortion inherent in CHIRP signalling. 

Critically IS3 also allows multiple ISP360 profilers to operate with minimised interference. This removes the requirement for ‘ping syncing’ traditionally required for multiple mechanically scanned profilers – enabling much faster scanning capability when using multiple profilers and thus decreased survey times.  

Ben Grant, Managing Director of Impact Subsea commented;

“We are excited to introduce the ISP360 Profiling Sonar to the market. The ISP360 is a game-changer for underwater profiling and positioning.

With integrated IS3 Impact Subsea Signalling Scheme 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.” 

Below is example imagery from the ISP360 Profiling Sonar.

The ISP360 offers a number of key features and benefits, including: 
  • 1° acoustic angular resolution 
  • 0.35mm timing resolution
  • IS3 Impact Subsea Signalling Scheme for minimised 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 

Ben Grant, Managing Director of Impact Subsea also commented;

“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.

If you’re looking for a powerful, all-in-one solution for your sonar profiling needs, the ISP360 is the perfect choice.”
