Abstract

In this work, an alternative navigation scheme for improving the performance of inertial navigation systems onboard guided munitions, missiles and unmanned platforms is investigated, to be used in case of a theater or country-wide GNSS (Global Navigation Satellite System) jamming scenario. Previously laid ground based beacon network is used by the aerial platform's EO/IIR (Electrooptic/ imaging infrared) seeker for bearing-only measurements and position updates are performed by the use of modified artillery survey algorithms based on triangulation techniques. Three angle-only passive position fixing techniques are offered for position updates. Effects of beacon placement geometry are analyzed and a tool for the optimal laying of beacons under several factors and, constraints is developed.
