SAFESYNC - High Performance Time Synchronization System-1

WITH PRECISION RUBIDIUM/OCXO OSCLLATOR 72/184 Channel GNSS Engine Supports GPS/QZSS, GLONASS,BEIDOU,GALILEO & IRNSS Anti spooﬁng and Anti jamming detect Features. 1 Gbps / 10/ 100Mbps NTP Server Synchronization over ETHERNET & FiberOptic Highly stable Rubidium/OCXO Oscillator Programmable pulse per second One micro second per day hold over Accuracy GPS GLONASS Monitoring Software (RHEL and Windows) Customized for defence application Safesync is a high performance Timing Synchroniza�on System provides synchronized Time and Frequency output.The unit is conﬁgured to provide appropriate �ming interface data at designated connectors mounted on the backpanel. The unit generates highly accurate disciplined 1PPS signal from an internal highstability Rubidium that is synchronised with reference to 1PPS signal from the GPS/ GLONASS/ SBAS/ IRNSS receiver along with the reference frequency that is phase synchronised to GPS / GLONASS/ SBAS/ IRNSS 1PPS signal. MECHANICAL DRAWING: FRONT VIEW REAR VIEW This is achieved by using an 72/184 channels Engine . GPS/ GLONASS/ IRNSS /SBAS receiver which tracks every visible satellite and maintains accurate and reliable time While tracking GNSS is accurate to <15nsecs to UTC. Beyond accurate NTP time stamping, this precision is excellent for generating the standards 1PPS and 10MHZ outputs. The unit is specially designed to meet the requirements of timing and synchronisation applications. On power up the unit enters phase lock mode and Rubidium gets disciplined with respect to GPS/ GLONASS,IRNSS. The built-in Rubidium Oscillator keeps the TSS extremely accurate while servicing NTP in the event GPS/ GLONASS service is interrupted. The unit is built to meet the EMI/EMC speciﬁ -cations as per MIL-461E standard. Informative status LEDs provides health of the system. Bright Vaccum ﬂuorescent di
