A New Method for the Determination of Deflections of the Vertical from Astrogeodetic and Inertially Derived Data,
Abstract
The paper first presents a review of prior developed methods for the determination of deflections of the vertical from astrogeodetic and inertially obtained data under consideration of gyro bias eliminations in Litton's local-level system. It then derives a Wiener-type optimal solution in semi-flat terrain under utilization of the collocation method in physical geodesy with prior emphasis on non-linear gyro bias removal and discusses the ramifications of presently and potentially available gyro and accelerometer hardware. Thereafter, a refined advanced method and deflection determination in strongly mountainous terrain is addressed under possible modification of the semi-flat terrain solutions and employment of spatial collocation. Finally, consideration is given to the associated problem of area adjustment solutions. (Author)
