Time and Frequency Server with GPS M-Code Receiver

Microchip Technology’s new time and frequency server with an embedded M-Code GPS receiver gives protection to military communication systems, radar and networks from the threats associated with intentional GPS jamming and spoofing, as well as cybersecurity risks to critical infrastructure. The U.S. Air Force GPS Directorate approved the SyncServer S650 M-Code for use in support of military communication systems, radars and networks.

The encrypted M-Code signal is mandated for mission-critical Department of Defense (DoD) applications in hostile environments.  SyncServer S650 M-Code provides a secure, accurate, flexible platform for synchronizing mission-critical electronic systems and instrumentation for DoD programs requiring jam-resistant, encrypted time and frequency signals from the  M-Code Precise Positioning Service (PPS).

The SyncServer S650 M-Code is a rack-mounted server device that synchronizes to the atomic clocks aboard GPS satellites via M-Code. The S650 M-Code leverages new technology to provide enhanced anti-jamming protection and further hardening against spoofing, providing greater accuracy, and improving operator ease-of-use for key loading.

Harder to jam than commercial CA-Code GPS, M-Code provides a more secure signal than the commercial CA-Code or SAASM P(Y) signal, with greater accuracy. The instrument also is easier for operators to load crypto keys.

The SyncServer S650 M-Code can utilize Microchip’s FlexPort technology for multiport, user definable output signal configurations for Inter-Range Instrumentation Group (IRIG) timecodes, pulses and a variety of signal types essential for military communication, radars and network system synchronization. This is coupled with Microchip’s NTP Reflector technology for robust security, accuracy and reliability of network-based time services such as Network Time Protocol (NTP) and Precision Time Protocol (PTP). Other features include:

  • Four standard GbE ports, all with patented NTP hardware time stamping, with two additional 10 GbE ports optional
  • Contains most popular timing signal inputs/outputs standard in the base timing I/O module (IRIG B, 10 MHz, 1PPS)
  • Web-based management with high security cipher suite
  • Rubidium atomic clock or OCXO oscillator upgrades
  • Superior 10 MHz low phase noise options

Microchip has been delivering the SyncServer S650 to synchronize business critical and mission critical operations across all industry segments since its commercial introduction in 2016.
