Abstract
Gravity gradient measurements taken by an accelerometer type gradiometer are optimized by tilting the measuring plane of the instrument by a selected angle above and below the horizontal to obtain data that can be differenced or otherwise processed to remove instrument bias and by taking data at first and then at a second orthogonal azimuth heading to obtain absolute non-relative gradient measurements.
