The FGPS suite of software has been developed in the field and office using real data acquired by all the major geophysical contractors and under a multitude of configurations and conditions. In addition to the academically approved and accepted methods, the software employs proprietary algorithms and methods of data storage which enable optimum performance at low cost, without compromising the quality of the results obtained.

This software is available for lease or purchase, with full 24 hour technical support.
