U.S. military and allied forces in upcoming exercises will put to the test commercial technologies that could help detect GPS jamming or other activities that disrupt satellite-based navigation. The project is led by the Defense Innovation Unit (DIU), a Pentagon organization focused on commercial technology. DIU is working with vendors to develop prototype systems that use data from satellites and other sources, artificial intelligence and machine learning tools to locate intentional interference to GNSS signals. “Mapping GPS disruptions and contextualizing patterns of behavior are key to mitigating the effects of degraded PNT as well as enabling safety of navigation under such conditions,” DIU program manager Lt. Col. Nicholas Estep said Aug. 17 in a news release. “Instead of developing, building and deploying hardware tailored for collection of navigation warfare operations, we are accessing currently available commercial data and analytics to address the need for PNT situational awareness,” Estep said.
