Abstract:	Precision aerial delivery of current electro-optical and laser guided munitions on high value targets provides enormous benefits. However, crucial deficiencies in these weapons, such as the lack of adverse weather capability and high cost, limit their utility. Coordinate bombing using INS/GPS (Inertial Navigation System/Global Positioning System) guidance can provide an effective means of adverse weather attack. In addition, the GPS accuracy removes the need and expense of a terminal seeker for many targets. However, an INS/GPS guided weapon requires ma target coordinates from some external source. The problem of real-time target recognition and accurate designation must be solved before coordinate bombing is effective against unsurveyed, relocatable targets. Synthetic Aperture Radar (SAR) mapping of the target area enables adverse weather targeting. The largest SAR target designation error source is usually the error in velocity reference provided to the radar for processing Doppler returns. A tightly coupled INS/GPS solution, should provide a greatly improved velocity reference for SAR targeting, and thus reduce weapon terminal impact errors. The “GPS Exploitation for Precision Targeting" program is investigating improvements in INS/GPS integration, and other targeting error sources, requiled to provide accurate, adverse weather targeting.
