Acoustic Inertial Hydrological Survey Equipment Detection Range 0.2~250m
HP1201 Range 0.2~250m Resolution <2cm Acoustic-Inertial Integrated Sounding Instrument
HP1201 high-precision integrated acoustic inertial sounding instrument adopts ultra wideband technology and integrated acoustic inertial technology, which solves the difficulties of difficult time synchronization, no attitude measurement and correction, poor measurement accuracy of traditional sounding instrument. The sounding results are more stable and accurate, and can adapt to a wider range of water depth and water quality environment. It is a sharp tool for bathymetric measurement in inland rivers, lakes and at sea. It is mainly used in the hydrological survey industry to serve more industry customers who need high precision of bathymetric survey and underwater topographic survey.
It can be equipped with underwater robots (ROV, AUV, etc.), unmanned ships, surface ships and other operation platforms, which is suitable for a wide range of platforms, calibration free installation, convenient and fast. The output information is rich, including water depth, water temperature, attitude and heading, position and waterfall sound map of suspended target. This type of sounding instrument can be used in underwater topographic mapping, bathymetric survey, underwater environment survey, fishery resources survey, underwater section data acquisition and other purposes.
Using standardized protocol interface, SDK development kit can be provided to users to customize data driver. It can be interconnected with various commonly used acquisition and measurement software to facilitate users to access the existing acquisition software and post-processing software.
HP1201 high precision acoustic-inertial integrated sounding instrument integrates inertial navigation system and acoustic image technology on the basis of traditional echo sounder, which can solve the problem of accuracy loss caused by ship shaking in the process of operation, and can also provide acoustic image when providing water depth data.
