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 jamming scenario. Previously laid ground based beacon network is used by the aerial platform’s EO/IIR 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, reverse intersection which is a modified intersection method, two point resection and three point resection. Effects of beacon placement geometry are analyzed and a tool for the optimal laying of beacons under several factors and, constraints is developed.
