Abstract:	Results are presented here of a feasibility study of reIative GPS pexformancz for a vpical m&ting application. Laboratory and van test data were used to investigate the effectiveness of engaging a fixed target with a GPS equip* weapon when the target has been located by a GPS-equipped aircraft. The relatise nature of the targeting process derives from the fact that the line of si$t is computed from a GF’S based target position estimate and we;ipon position eSthII2Le. under conditions of common sitelh oxking Tests were conducted with two Non-Devclopmcntal Item 01) nnl-ipation systems in side-by-side rest cotigurations. The weapon na\Qation system consisted of the HoneywellKI H-7MG Inlcgratcd GPS Inertial (IG’? system. The launch platiorm navjpation system consisted of a Licron SNU-84-IE IX5 integrated with a Collins MAGR via a IS_53 data bus. The Tess results substantiated the premise that two GPS bs& navigation systfzns c,xhibit similar positions errors trends when tnctig tie: siime Set of satellites. The test. results also indicated that SJI& non-common. bias-like CITCKS are present that do not cancel completely in pi rcktive differencin2 technique. VLviations in performance a~ a function of weapon flighl tie were examined.
