GPS timing is used in electric power grids for fault detection, substation control, protective relays, in synchrophasors, and numerous other applications. As we move to “Smart Grid,” timing will become even more critical.

The problem is that GPS signals are very weak and easy to disrupt. They have been disrupted by solar flares, malfunctioning electrical and electronic equipment, and poorly mounted TV antennas. Small illegal GPS jammers have become popular with privacy seekers and criminals, and U.S. adversaries are known to employ larger jammers that can deny GPS over very large areas.

The RNT Foundation is working to safeguard GPS services by advocating policies and systems to Protect, Toughen, and Augment them.

Here are a few of the many resources we have available on GPS and electric power:
