New Processing Technique for High Accuracy Gravity Data

For the processing of gravity data new software DRIFT was developed with the aim to increase significantly the accuracy of the resulting dataset. Special spline procedure was applied to analyze observed data and to evaluate more realistic drift curve, instead of linear approximation. The software was tested on various gravity data, from mineral exploration and microgravity to 4D gravity. It was proved that the standard deviation was reduced to less than 50% of original value. Increased accuracy enabled to investigate very low amplitude gravity signals.
