Abstract

The effect of gravitational disturbances prior and subsequent to compensation with prepared maps for advanced tactical fighter application is quantified. The avionics issues associated with implementation of vertical deflection compensation are addressed. It is shown that a unique implementation concept designated the VERDICT (vertical deflection inertial compensation terminal) can provide the required compensation and is adaptable to a wide variety of inertial navigators. The authors document the validation of the VERDICT concept and present an approach to the hardware design of VERDICT. It is concluded that the combination of advanced mass storage and digital processing electronics, and the availability of large gravity databases from satellite altimetry make the VERDICT concept feasible for near-term implementation
