The HY1202 is a series of sound velocity profilers ideally suited for real-time sound velocity measurement in shallow and deep waters down to 1,1000 water depth. The HY1202 often serves for depth correction of SBE, beam-angle correction of MBE and sound ray curvature correction. Besides fixed installation on survey vessels, the HY1202 deep-sea SVP can also be integrated in autonomous navigation platforms such as submarines, AUVs and ROVs to complete special tasks.


HY1202 SVP adopts “Time of Flight”technology and improves the accuracy to 0.05 m/s, which reaches to world-leading level. It is connected to MBE or other instruments via cables, which achieves power supply and RS232 data communication.
