Building resilience into Global Positioning System (GPS) timing and frequency receivers is crucial in the 21st century. Since the presidential directive on U.S Space-Based Position, Navigation, and Timing (PNT) and Critical Infrastructure Protection (PPD-21), federal agencies have been advancing their efforts when it comes to GPS and Global Navigation Satellite System (GNSS) capabilities.
The most important thing a soldier must maintain on the battlefield is Situational Awareness: being able to identify and understand what is happening around you and how it pertains to the mission. Over the past few decades, Global Positioning System or “GPS” technology has become an integral tool for helping US forces stay aware of their surroundings.
One of the most significant changes to the way the military operates has been the integration of GPS for positioning, navigation, and timing purposes, which has given military forces unprecedented command and control over battle grounds. Troops and command centers are now in a state of continuous situational awareness, with an endless stream of data being added to military servers at all time.
