Time Synchronization Device
EKRA-TS-SV02A

SV02A device is designed to generate and store the time scale synchronized using signals from global navigational satellite systems GLONASS/GPS, as well as to display current date and time

SV02A device synchronizes its own clock using accurate time signals received from GLONASS/GPS, and serves a source of Stratum-1 level accurate time for all devices connected thereto

SV02A device has a metal case and shall be mounted on 19″ rackmount
