Sound Speed Sensor
The sound speed in water, such as at the ocean surface or surrounding a remote operated vehicle (ROV), is measured by sensors that use “time of flight” technology to provide low noise, high accuracy and high resolution data. Time of Flight (TOF) describes various methods and sensors that measure the time it takes for an object, particle or wave to travel a distance through a medium. Sound speed sensors are often installed on ships flow-through systems and on ROVs.
The resolution of the sound velocity sensor on the ROPOS navigation system is 0.001m/s with an accuracy of +/- 0.017m per second.
