Every camera, console and archive log in your facility deserves the same clock.

A GPS/GNSS PTP grandmaster is an on-premises Stratum-1 time server that derives UTC directly from satellite signals rather than from internet-based NTP pools. For a broadcast facility, this means cameras, automation systems, MAM databases and playout servers share a single, traceable time reference that stays locked even on an isolated production network with no path to the public internet. It removes the dependency on external infrastructure and gives engineers full visibility and control over their timing system.

The PreciseSync-GMC-300 achieves 15 nanosecond accuracy with GNSS signal lock, with a PTP timestamp accuracy of less than 100 nanoseconds to UTC at the grandmaster port. Client-side accuracy depends on network architecture, switch delay measurement capability and the PTP implementation of end devices, but the grandmaster reference itself stays within the 100 nanosecond window under normal operating conditions.

Yes. The same chassis distributes IRIG-B (AM and TTL), differential pulse and DCF77 outputs to SDI-era slave clocks and reference equipment, while simultaneously serving PTP over Ethernet to IP-native routers, consoles and video infrastructure. A facility can migrate to IP at its own pace without running two entirely separate time systems in parallel, which reduces both operational complexity and the risk of synchronisation mismatches during the transition period.

The on-board OCXO oscillator engages holdover mode immediately, maintaining microsecond-level timing accuracy throughout the signal loss period. SNMP traps and syslog notifications alert the engineering team the moment the satellite lock is lost, so technicians can investigate and resolve the antenna issue before it has any impact on on-air output or production logs.

The GMC-300 (1U rack) covers most broadcast studios and OB vehicle racks where a single high-performance grandmaster is sufficient. The GMC-300-R is the choice for master control rooms and playout centres that require full hardware redundancy across GPS receiver, master clock, comparator and power supply within a single 3U chassis. The GMC-300-D (DIN Rail) is designed for space-constrained technical rooms, OB vehicle panels and compact broadcast racks where a 19-inch rack unit is not practical.

A single PreciseSync-GMC-300 can distribute PTP to any number of IP-connected clients and drive slave clocks and display units simultaneously. Most multi-studio facilities deploy one grandmaster per production network or per site, with each unit locked to the same GNSS reference for a consistent UTC base across the building or campus. For mission-critical facilities where hardware failure is not an option, the GMC-300-R provides built-in component-level redundancy within one chassis.
