Airborne Vector Gravimetry with an Aided Inertial Survey System
The purpose of this paper is to define the fundamental problem of airborne vector gravimetry using an inertial survey system and explore the role that different augmenting sensors such as GPS and a star tracker can play in this process. Different system architectures that are potential candidates for obtaining measurement accuracies required by the geodesy and geophysics community and the exploration geophysics community are reviewed and their suitability for providing a technical solution is assessed.
