DOT Needs Better GPS Interference Tracking: GAO

DOT needs to improve its process for identifying and documenting GPS interference incidents, per a GAO report Thursday. It said DOT identified 196 potential GPS interference incidents in the first five months of this year, but its process doesn't include all available user reports and its data has inaccuracies. "Without a process that produces quality GPS interference information, federal efforts to quickly respond to and stop interference could be delayed," GAO said. It said DOT has worked to improve transportation sector resilience to GPS interference, but it's not clear how those efforts improved resilience. The report recommended DOT document its incident identification process and develop a strategic approach to resilience.
