NATO Creates Tool to Address Signal Degradation

nato-creates-tool-to-address-signal-degradation

The NATO Communications and Information Agency's new software works to facilitate assessments of areas prone to degradation of signals from global navigation satellite systems. The Radar Electromagnetic and Communication Coverage Tool or REACT allows users to estimate areas where interfering signals may affect the performance of GPS and other GNSS technologies that provide positioning, navigation and timing data, NCIA said Monday.
