GNSS Application Atomic Clock
Our modern world is interconnected with advanced technologies. All aspects of our lives are dependent on our ability to measure space and time every day. “Where are we and what time is it”? These two basic questions connect us to all aspects of our modern, technologically driven lives. Satellites, in this case, Global Navigation Satellite Systems (GNSS) also known as Positioning Navigation and Timing (PNT) satellites, have quickly become an integral part of our daily lives and are now an unseen but vital utility that is used throughout the world. A day without GNSS satellites would be a very bad day indeed. Most people in the world use GNSS systems every day, without even knowing it. Only when it disappeared would they understand just how much they depend on it for carrying out their daily activities.
