Army wants jam-proof GPS for missiles

Concerned that missile GPS guidance can be jammed, the Army is looking for more secure position, navigation and timing, or PNT, guidance systems.

The Army wants to take advantage of advances in GPS technology. 

"Recent techniques that preprocess RF data, apply advanced signal processing within software defined receivers, or incorporate precision clocks have demonstrated PNT improvements when the GPS receivers are subjected to electronic attacks," the Army research solicitation read.

"Vector tracking and deeply integrated GPS receiver architectures have shown the ability to improve signal tracking while the platform is performing high-g maneuvers or when the J/S ratio is elevated," the Army noted. "These systems improve tracking, and therefore PNT, by exploiting cross correlations that exist in the received GPS signals and knowledge of platform dynamics."
