Multisensor Approaches for Determining Deflections of the Vertical.

Abstract

This final report documents the second phase of a study of methods for determining deflections of the vertical. In this phase multisensor techniques involving astrogeodetic, gravimetric, inertial, and gradiometric methods have been examined. The combination approaches discussed herein are those found to offer most promise in terms of accuracy, logistical convenience, and/or cost. Specific techniques treated in detail are the astrogeodetic method approached from a minimum variance estimation context, alternative moving base measurement techniques using supplemental astrogeodetic data, and regional adjustment of multiple tracks of inertial survey system measurements. Cost and logistical considerations for key single and multisensor deflection determination alternatives are reviewed. (Author)
