Datasheet

HydroPos

Overview

The HydroPos Seismic Version 2 Acquisition and Post Processing module is a software programme that allows the user to plan, acquire and post process acoustic data from Sonardyne’s OCB12 acoustic system and 7815 transponders.

HydroPos is designed to run under Windows XP or Windows 7 and requires a PC capable of running the operating system. A minimum screen resolution of 1024 x 768 is recommended.

Line data can be imported in OGP P1 and SEG SPS formats as well as a CSV file and once loaded transponder locations can be simply added either by “hand” or via the HydroPos Seismic Re-Programmer or RFiD Cable deployment modules.

During Acoustic Acquisition HydroPos commands the OBC12 transceiver to interrogate the relevant 7815 transponders and logs the acoustic replies. An initial online positioning solution is available on the acquisition screen with a visual indication of positioning accuracy.

HydroPos also provides on-line vessel positioning information to the user, to enable acquisition by the most efficient sail line plan, and at the optimum interrogation speed and geometry as well as an independent helmsman’s display to provide vessel guidance. The helmsman’s display is available on other machines on the same network as the acquisition PC.

On completion of data acquisition, the raw data can be exported from HydroPos into the OGP P2/94 format for submission to the client.

 HydroPos is also able to post process the raw data. This simple procedure also allows the operator the ability to automatically or manually remove any ranges which obviously do not fit the solution.

Data can be processed several times allowing for different parameters and scenarios to be tried; alterations to sound speed and solving for depth or fixed depth for example.

All raw and processed data is stored in a single, user-selectable, logging file (.LOG) to allow easy archiving of the data. The recorded .LOG file contains all the online acquisition parameters as a header, followed by blocks of recorded data. This enables the data to be easily processed as blocks of data, either at a later date, or at a remote location if required.
