IAI unveils improved anti-jamming GPS

March 6 (UPI) -- Israel Aerospace Industries has unveiled an upgrade to its satellite operational navigation systems, which it says repels attempts at jamming.

While most navigation, communication and electronic warfare systems rely on continuous availability of multiple satellites for navigation, the majority of worldwide avionics systems are vulnerable to localized, low-power jamming emitters.

"In the Army, we have recognized that PNT [Positioning Navigation Timing] is a critical enabler of our warfighting capability, and that GPS is the predominant materiel solution that we rely upon," the U.S. Army said in a 2015 statement.

IAI said its ADA-O development features an advanced architecture and can defeat jamming efforts. The system can be installed on armored vehicles, communications carriers and other land-based platforms.

The ADA approach to Assured PNT [Positioning Navigation Timing] involves the use of advanced digital processing techniques that provide a high-level of immunity in severe and dynamic multi-jammer scenarios, the IAI statement said.

The company said it recently sold an ADA package for "tens of millions of dollars" to an unnamed Asian-Pacific nation's military.
