SecureSync® Time and Frequency Reference System


Safran SecureSync

SecureSync harnesses Safran’s leading PNT technology into one flexible, modular platform designed to synchronize critical defense and commercial infrastructure that requires extreme reliability and security.

SecureSync is built on a highly configurable platform to offer precisely what customers need at the lowest cost of ownership. Greater resiliency in SecureSync is available through a multi-layered approach that can leverage anti-jam antennas, Safran’s complete Interference Detection and Mitigation (IDM) suite, as well as time error minimization with high performance internal oscillators. Qualified military customers are also eligible for secure military signals such as SAASM and M-Code.

Interference Detection & Mitigation

SecureSync also offers embedded interference detection and mitigation to help you identify the presence of jamming and spoofing. Interference detection is a key enabler for greater resiliency in critical infrastructure, as defined in the DHS Resilient PNT conformance framework and the federal PNT Executive Order.

We also offer the 8230AJ GPS/GNSS Anti-Jam Outdoor Antenna which uses a three-stage low noise amplifier, a mid-section SAW, and a tight pre-filter to protect against saturation by high level sub-harmonics and L-band signals. The Anti-Jam antenna rejects signals for the lower elevation angles – where most of the interference comes from.

Alternative signals such as the STL Option are also available which, as an encrypted signal 1000x stronger than GNSS, is an ideal solution for augmenting GPS or other GNSS constellations for resiliency and security or as a standalone indoor solution when roof access isn’t an option.


SecureSync is the key enabler of a highly available time and frequency synchronization distribution architecture. It adapts to demanding infrastructure environments, with extended temperature support (-20°C to +65 °C). Time distribution to legacy systems can be achieved with a range of synchronization signals, while timing protocols (NTP, PTP) are available for synchronizing of recent systems through the networks. And, alternative signals including LEO PNT are available such as the STL option.
