Rugged GPS Time & Frequency Reference – VITA 75

As the exclusive UK distribution partner for Spectracom, Steatite says it can provide customers with access to the latest precision time synchronisation technology. Its latest offering is the VersaSync GPS master clock and network time server. It delivers software-configurable time and frequency signals, even in GNSS-denied scenarios, says the company.

It supports both precision time protocol (PTP) and network time protocol (NTP) synchronisation standards. This robust, military grade unit (MIL-STD-810G) server is lightweight (0.91kg) and portable. Its robust, compact (147.3 x 127.5 x 63.0mm) and VITA 75-compliant design facilitate its integration with existing hardware. I/Os can be configured to accommodate a variety of timecode formats, such as IRIG, HaveQuick, 1PPS, xPPS. A choice of GNSS receivers is also offered.

Each VersaSync unit has a built-in, high stability oscillator/clock resource (either OCXO or CSAC based, depending on the degree of exactitude required) that enables time and frequency accuracy to be upheld for extended periods without GPS/GNSS support. It can be re-synchronised by an external reference if required.

Applications include large scale UAVs, military vehicles, radar equipment (civil or military) and marine (sonar systems). Operational temperature range covers -45 to +85 degree C. They can also cope with 95 per cent humidity levels and have strong resilience to shock (20g) and vibration (7.7g). Functioning at altitudes up to 13,000m, they are suited to airborne deployment.
