Timing Application

Besides tracking and navigation, GNSS signals are widely used for Precision Timing and Time Synchronization functions across networks because precise time is quite crucial to lots of applications. The reason is that each GPS satellite has multiple atomic clocks which can contribute precise time data to the GPS signals. LOCOSYS Timing Modules can be applied for so many applications, like 5G Femtocell, Microcell , Base station, High Speed Router, Network Switch, Traffic Control System, Energy Control System, Data Network Center, Video Surveillance System, Smart Grid System, Industrial Computer, IoT (Internet of Things), and so on.
