Timing Application

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.

LOCOSYS GPS Timing Application real case

LOCOSYS ST-1612i-GT modules can simultaneously acquire and track multiple satellite constellations that include GPS, GLONASS, GALILEO and QZSS. ST-1612i-GT feature accurate PPS for timing applications. It has T-RAIM algorithm and position hold auto survey mode.

LOCOSYS ST-1612-T module can simultaneously acquire and track multiple satellite constellations that include GPS and GLONASS. The ST-1612-T has timing features of T-RAIM algorithm and position hold auto survey mode. Besides, 1PPS output is available with only one visible satellite. Its precision GNSS timing is suitable for applications such as communication base stations and electrical power grids.
