PTD-CHIRP2 SBP（AUV）

The PTD-CHIRP2 system, independently developed by TIANDUNBJ TECHNOLOGY CO., LTD., is a new generation of shallow-water profiling system specifically designed for marine geophysical surveys. The system supports both automatic and manual measurement modes, making it suitable for measuring water depth and shallow-water profiles. With a maximum penetration depth range of 500 meters and a maximum penetration depth of up to 50 meters, it boasts excellent stratigraphic resolution (up to 15 centimeters). The equipment consists of a signal/data processor, a transducer, and a PC computer, which can be integrated into an instrument cabin and operated through a streamer system for deep-sea operations. The PTD-CHIRP2 system not only excels in technical performance but also plays a significant role in marine geophysical surveys, providing users with precise geological information and facilitating the progress of deep-sea resource exploration and environmental research.
