ASB Systems, Coastal O's affiliate in Mumbai, India, has been hard at work on the development of our new ADCP data collection and processing modules, which will be included in the next release of HYPACK® Max. These modules have been designed to log data from RD Instruments' Workhorse ADCP's.

The first module developed is the ADCP Logger. This module is designed to run alongside the HYPACK® Survey program, logging ADCP data simultaneously with HYPACK® raw data. The program uses RDI's ADCP configuration files to deploy the ADCP. The Logger has numerous display windows, including velocity profiles, intensity profiles, current magnitude, and tabular displays. The logged data files contain RDI raw data from the ADCP, in addition to navigation data passed from the Survey program through Shared Memory and into the Logger. The user also has the option to log standard RDI *r.000 files.

The next module is the ADCP Profile program. This program allows the user to load HYPACK's edited files and ADCP files, and get a cross sectional view of the survey line, echosounder depth or ADCP bottom track, and also display the current velocities. The user can then print or plot these profiles, and also calculate discharges and print a report.

Last but not least is the ADCP to DXF program. This program was created so that the user can create DXF current vectors from the data collected in Survey and the ADCP Logger. The user can specify vector length, vector type, current depth level and current speed units. These DXF vectors can then be imported into CAD/GIS packages, or plotted right in Hyplot®.
