Weapon systems relying on integrated GPS/INS navigation technology are susceptible to jamming from external sources. Anti-jam GPS navigation system can be realized by using spatially separated GPS antennas together with adaptive signal processingtechnology. The central element of such an anti-jam GPS navigation system is the adaptation algorithm. This proposal advances the development of fast responding, stable, adaptive filter algorithms based on recently developed nonlinear control technology.Adaptation algorithms proposed here can provide convergence guarantees and efficiencies not available in existing algorithms. Phase I research will demonstrate the use of these new adaptation algorithms in the synthesis of anti-jam GPS navigation systemusing a six degree-of-freedom simulation. Phase I research will also identify the computational requirements for implementing the anti-jam GPS navigation technology. Phase II work will develop a prototype of the anti-jam GPS navigation system usingcommercial off-the-shelf components. That work will also demonstrate the benefits of combining the anti-jam GPS technology with previously developed guidance-control techniques to develop robust flight control systems for a precision munition. Adaptationalgorithms developed under the present research has extensive applications in next generation signal processing systems. Applications include adaptive beam forming in phase-array radars, cellular telephony and video teleconferencing over Internet. Anti-jamGPS technology can provide reliable navigation sensors for the next generation air traffic automation and UAV systems.
