Safesync

Safesync

SAFESYNC is a high performance Time Synchronization System provides synchronized Time and Frequency output. The unit is configured to provide accurate timing data at designated connectors mounted on the back panel.

The unit generates highly accurate disciplined 1 PPS signal from an internal high stability OCXO/Rubidium that is synchronised with reference to 1 PPS signal from the GPS / GLONASS / SBAS / IRNSS receiver along with the reference frequency that is phase synchronised to GPS / GLONASS / SBAS / IRNSS 1 PPS signal.

This is achieved by using a 72/128 channels multi GNSS Engine. GPS / GLONASS / SBAS / IRNSS receiver which tracks every visible satellite and maintains accurate and reliable time.
