Army Acts to Bolster PNT, EW Capabilities

Jeff Brody

The U.S. Army is working to boost the capacity of its ground-based precision navigation and timing technologies to address spoofing threats, or when signals are disrupted to produce inaccurate information. The service branch said Thursday that its current PNT technologies are still prone to spoofing issues caused by various factors such as weather, terrain or near-peer adversaries.

Col. Nick Kioutas, the Army's PNT project manager, said the branch has adopted a layered approach to boost the accuracy on position and timing data, with the integration of inertial-based navigation systems, odometers and other non-radio frequency tools.

"Our systems will integrate all these data sources to determine which one we can trust the most," Kioutas said. 

The Army also plans to gain access to more PNT data sources via external networks of the global positioning system. The service branch is also working on a new Electronic Warfare Planning and Management Tool in addition to PNT efforts. The tool would work to facilitate the control and management of EW assets supporting land missions.
