Safran SecureSync 2400 Network Time Server

The Safran SecureSync 2400 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. 

Resilient Timing for Evolving Requirements

Resilient Timing depends on securing the time reference acquisition and timescale keeping, in the face of GNSS interference. Government recommendations, like the Executive Order in the US or the Cybersecurity Act in European Union, pave the way for future regulations in this domain. 

The Safran SecureSync product ecosystem offers a number of solutions to address GNSS threats. With a layered-defense approach, each protective layer increases the sophistication required to compromise, minimizing chances for successful attack. 

SecureSync relies on the proven Interference Detection Suite, allowing jamming and spoofing detection. Threats are mitigated by highperformance internal oscillators, or through strong modularity and choice of input interfaces, building redundancy into the timing system architecture. 

Whatever your industry, there is a cost-effective SecureSync configuration that keeps your time distribution accurate and available. 


Safran SecureSync 2400 is designed with security in mind, combining cybersecurity best practices, including VLAN support account/access management, authentication, encryption, security event logs, network features disabling, as well as regular, secured firmware updates to keep pace with the latest vulnerabilities and protocol improvements. 

Networking that Scales

Safran SecureSync 2400 provides strong and scalable networking capability, thanks to higher embedded processing power. Two Gigabit Ethernet ports (one RJ45, one SFP) are available on the base unit enabling flexible network synchronization as a NTP server or PTP slave/ master, as a NTP stratum 2 server, or as a PTP slave/boundary clock. 

New generation network option cards (1204- 49 and 4A) provide additional dual and quad Gigabit Ethernet SFP ports, embedding their own processing capability and offering further capabilities as NTP server and future PTP slave/master. Scaling up network timing distribution or adding timing redundancy in the network becomes easy. 


For applications that use “physical” timing signals and require multiple interface types, Safran SecureSync 2400 offers unmatched modularity and a choice of more than 40 option cards. 

The base unit provides configurable Input/ Output timing interfaces (TTL pulse, RS232/ RS485, IRIG AM /DCLS), on top of 10 MHz and 1 pps outputs. If more interfaces are needed, the base unit supports either 2 (2402) or 6 (2406) option card slots, enabling whatever combination of frequency, phase, NMEA or Have Quick time codes, and network synchronization is needed. 


At the appliance level, SecureSync includes an optional, dual (redundant), hot swappable power supply combined with AC, 12 VDC or 24/48 VDC power modules. Modularity enables multiple time reference management as well as redundant time distribution architectures, which is instrumental to system- level reliability. Any failure is identified and reported in real time, reducing periods of unavailability. 


SecureSync 2400 embeds local and remote monitoring tools, including detailed event logs, real-time access to health and operation status, timing performance graphs, and alerts. Integration into automated monitoring systems is supported with legacy protocols like SNMP as well as the more recent REST API. Quick, local diagnostics are accelerated thanks to the front panel indicators and OLED display.
