Rowe EDU is a place to learn about ADCPs and DVLs. There will be short tutorials describing a specific subject. The tutorials will include a short video and written documentation to help you understand the topics. The goal of these tutorials is to teach you how to use your ADCPs and DVLs. There is also an online chat to talk to someone live to help you with your ADCP questions.
See our ADCPs and DVLs in the field being used by customers. View ADCP and DVL data and results. Get some helpful hints on how to use your ADCP or DVL.
Introduction A water profile measurement is a profile of a water column that gives the direction and speed of the water currents. Water Profile Description Bins So to create a water profile measurement, the water column must be broken up into bins (cells). The bin sizes and number of bins are set by the user using the CWPBS command and CWPBN commands. Blank The Blank area is the area before the first bin to ignore.
General Acoustic Doppler Current Profilers (ADCP) are hydro-acoustic instruments that are used to measure water velocities or currents over a specific range of water depth. ADCPs utilizes the Doppler effect to measure water velocity in discrete layers – essentially sending a sound signal of a specific frequency into the water column and measuring the sound signal return. The change in return frequency is proportional to the water velocity. ADCPs can be deployed in many ways, up-looking, down-looking, and side-looking.
This report presents the results of the RTI Seaseven dual-frequency ADCP operation in comparison with the RDI’s Workhorse 600kHz during the first phase of the RoeCaille 2019 campaign.
Introduction Typically a DVL (Doppler Velocity Logger) is used in 2 different types of navigation: Dead Reckoning Navigation DVL-Aided INS Navigation Dead Reckoning relies on the DVL for velocity, time and range to maintain a position. A DVL-Aided INS relies on the DVL to maintain position and account for drift. Dead Reckoning Navigation Dead Reckoning Navigation relies on the DVL for velocity, time and range to maintain a position.
