This report is a continuation of a previous OSU report, "Kinematical Geodesy" (1967). Part A gives basic principles and the theoretical foundations for the separation of gravitation and inertia by a combined accelerometer-gradiometer system, with applications to aerial gravimetry and to inertial navigation. In Part B, proposed methods for the geodetic use of second-order gradients are briefly described and evaluated. The new technique of least-squares collocation avoids the shortcomings of those methods. The application of this technique to the use of gradients for the determination of the gravity field and of spherical harmonics is investigated.
