Silas Acquisition

SILAS is a complete data acquisition, processing and interpretation package to cover a wide range of tasks

It is source independent and can handle analogue or digital data from boomers, sparkers, parametric and chirp systems. Used by professionals such as universities, dredgers, geophysical & hydrographic surveyors.

Description

Digital data-acquisition for high resolution seismics Features: - Calibration of source signal - All raw reflection data are recorded on harddisk - Online link with navigation system for synchronisation and position control - Real-time data acquisition control - Vertical data density can be determined by user by setting the sampling rate - Control of the number of samples per shot, without interruption of data acquisition - Adjustment of recorded depth interval - Modifications of settings are recorded in shotheader - Real-time monitoring of reflected signal intensity - Real-time monitoring of incoming data quality - Real-time tracking of seabed/acoustic interface or muddensity level
