Image: J. Sherman/NIST Blog Editor's Note: Good to see NIST weighing in on this issue. The high level recommendation that the nation needs a coherent timing architecture that involves space, terrestrial broadcast, and fiber assets is consistent with numerous other...

Image: Shutterstock Blog Editor's Note: Power grids are not one of the things folks first think of when discussing dependence on GPS.  And some grid engineers don't like to admit it. We have heard them say "We don't need GPS to operate the grid, just to manage it." -...

Image: Shutterstock Blog Editor's Note: Perhaps this is a prelude to an invasion of Ukraine.  Regardless the Russians are not bluffing. Our intelligence and Space Force folks here in the U.S. say the Russians (and Chinese) can do it. What's the best way to protect...

Image: China Aerospace Science and Technology Corporation Blog Editor's Note: America used to think space was a safe place, so we put a lot of our most important assets there. We thought GPS was particularly safe because attacking a satellite was hard, and destroying...
