Microsemi SyncServer S350 SAASM

Versatile network time servers are often needed to meet the requirements for demanding, high performance network time synchronisation as well as supply traditional time and frequency technology. The SyncServer® S350™ SAASM provides unsurpassed NTP performance for Military networks while being the most versatile time server in the world for traditional time and frequency applications.

The SyncServer S350 SAASM’s GB-GRAM receiver is a third-generation GPS PPS, 12-channel receiver. The internal Ground-Based GPS Receiver Application Module (GB-GRAM) complies with the U.S. Government’s GB-GRAM program that fulfills a GPS Wing initiative to migrate to a defined, open system architecture for ground-based embedded military applications.

When it comes to synchronising the time on servers and workstations for mission critical DoD networks, the S350 SAASM sets new standards for security, accuracy, reliability and timing versatility in network time servers.

Multiple and Versatile Timing Configurations

The Stratum 1 S350 SAASM will automatically synchronise to GPS, IRIG, 1PPS, and 10 MHz sources. Users set the priority for smooth transition from one reference to the next if a higher priority signal is lost or regained. Time code inputs/outputs include IRIG A/B/E/G/NASA36/XR3/2137 in AM and DCLS formats.

Unmatched NTP Performance with Unparalleled Flexibility and Security

The S350 SAASM has four dedicated and isolated Ethernet ports, one of which is Gigabit Ethernet – more than enough to meet the need of servicing thousands of NTP requests per second while maintaining microsecond caliber timestamp accuracy. Multiple ports provide the flexibility to adapt to different network topologies as networks grow and change. It also supports a wide range of network protocols including IPv4 and IPv6, for easy management and seamless integration into existing and future networks.

Enhanced Security – Secure and Easy Network Integration and Management

The S350 SAASM provides very reliable and secure network synchronisation technology by combining multi-port network interfaces with multiple time reference technology and enhanced security protocols. RADIUS, SSL, Autokey, MD5, passwords, access control lists and more are standard for maximum security. All of the expected network management and monitoring protocols are standard in the S350 SAASM.

Supports Black Keys 

With the dual frequency S350 SAASM, the P(Y) code is received on both the L1 and L2 bands. The S350 SAASM supports encrypted and unclassified (controlled) Black Keys which can be distributed and loaded electronically. Decryption of the Black Key takes place within the SAASM module. Classified Red keys are also supported.

Hot Start Ready 

The S350 SAASM provides a port that supports a hot start via a DAGR, PLGR or other PPS device to facilitate direct acquisition of the P(Y) code within hostile environments where the C/A code is unavailable.

Easy To Set Up and Maintain 

SyncServers are the easiest to set up and maintain network time servers in the world. The front panel of the SyncServer is designed to quickly bring the server online with a few front panel keystrokes or DHCP. To fully configure the unit, use the very intuitive web interface or the step-by-step wizards for the most common operations.

Assured Perfect Timing 

The Stratum 1 level S350 derives extremely accurate time directly from the atomic clocks aboard the GPS satellite system. Reliability can be further enhanced via Stratum 2 operation by retrieving time from other user-designated time servers. All SyncServers can be upgraded to an internal Rubidium atomic oscillator to keep the time server accurate if the GPS signal is lost.

Alarm Relays for Monitoring Systems 

Aside from extensive software based alarms, the hardware based alarm of the S350 relays further enhance Alarming choices.

Compliant with Joint Chiefs of Staff SAASM mandate 

Taking into account the Joint Chiefs of Staff mandate that all newly fielded DoD systems using GPS shall use SAASM PPS devices after October 2006 (unless waivered), the S350 SAASM meets present and future military GPS requirements. The S350 SAASM is a Precise Positioning Service (PPS) GPS instrument that authenticates satellite signals (when keyed) with anti-spoofing (A-S) technology and corrects for Selective Availability (SA) if enabled.
