Microsemi Corporation has announced its TimeSource Enhanced Primary Reference Time Clock (TimeSource Enhanced PRTC), a new system protecting against serious threats associated with GNSS vulnerabilities.
It also enables telecommunications and mobile operators to meet the new G.8272.1 recommendation from the International Telecommunication Union (ITU). The stringent new ITU-T Recommendation G.8272.1 requires accuracy to within 30 nanoseconds (ns) or better when verified against a time standard such as UTC.
Microsemi’s new TimeSource Enhanced Primary Reference Time Clock protects against serious threats associated with GNSS vulnerabilities.
The TimeSource Enhanced PRTC “generates time” by producing its own independent time scale aligned with GNSS, while its phase, time and frequency signal outputs remain autonomous. This provides customers within the communications, power, public safety, data center and government network markets with a secure infrastructure, reducing dependency on GNSS and enabling network operators to retake control of the timing source used for network synchronization.
“Worldwide telecommunications, power utilities and other infrastructure customers are in critical need of protection against GNSS vulnerability, and Microsemi’s new TimeSource Enhanced PRTC provides a powerful, high performance solution to address this need,” said Randy Brudzinski, vice president and business unit manager of Microsemi’s Frequency and Time division. “In addition, maintaining less than 30 ns performance is important to mobile operators who require a high level of accuracy to support LTE/4G and the upcoming deployment of 5G.”
Massive deployment of GNSS as a timing source for synchronizing telecommunications networks (both wired and wireless) has created security risks to a point where governments, major telecommunications/mobile operators and enterprises are now urgently looking to protect their networks against both regional GNSS issues as well as the potential of a global GNSS outage. Microsemi’s TimeSource Enhanced PRTC works with the company’s cesium clocks to ensure time is generated in an autonomous manner. Specifically, the TimeSource Enhanced PRTC’s “source of time” aligns accurately with GNSS time without being dependent upon it—avoiding any vulnerability to threats caused by jamming and spoofing.
According to Research and Markets’ report from market research firm Markets and Markets titled, “Anti-Jamming Market for GPS by Technique (Nulling System, Beam Steering System, Civilian System), Receiver Type (Military & Government Grade, Commercial Transportation Grade), Application, End User, and Geography – Global Forecast to 2022,” the anti-jamming market for GPS is expected to reach $4.8 billion and more than 309,000 units by 2022, at a compound annual growth rate (CAGR) of 7 percent and 10 percent, respectively, between 2016-2022. Demand for secured weapons guided systems and increasing vulnerability of GPS signals due to development of low-cost GPS jammers are the major growth drivers of the market.
Microsemi’s technical experts will be showcasing the new TimeSource Enhanced PRTC, along with its integrated GNSS Grandmaster (IGM) 1100 series, SyncServerS600 series, TimeProvider 2700 and TimeProvider 5000, in booth #17 at the International Timing & Sync Forum (ITSF), taking place Nov. 1-3 in Prague, Czech Republic.
Symmetricom, Inc., has introduced new RoHS compliant versions of its existing SyncServer S200 and SyncServer S250 GPS Network Time Servers. Designed for large or expanding IT enterprises, the cost-effective SyncServer S200 and S250 with optional rubidium-based atomic clocks will reliably continue operational service for extended periods when primary time sources are impaired.
Accurate network time-keeping is essential for modern data networks to support a number of key functions — including precision time stamping, scheduled data backups, network management and security. These functions all rely on networked clocks to stay synchronized with each other. By using enterprise owned servers, companies are better poised to ensure accurate, reliable and more simplified network timing and synchronization, Symmetricom said.
The European Union’s Restriction of Hazardous Substances directive (or RoHS) assures environmental responsibility for the materials used in electrical and electronic equipment. The SyncServer S200 and S250 now offer network managers and engineers RoHS certified, entry-level time servers that still allow them to take advantage of rubidium-based clock technology. Unlike the more commonly deployed time servers that leverage temperature-compensated crystal oscillator (TCXO) and oven-controlled crystal oscillator (OCXO) technologies, the rubidium-based SyncServers provide superior holdover — technology that allows the network to continue to operate with accurate timing when the primary reference (usually GPS) is temporarily impaired due to events such as GPS jamming, antenna breakage, or solar interferences.
Communications and information technology managers can now take control of their network timing and synchronization and be assured of very accurate timing in their network that will not degrade or disrupt services during long periods where holdover is necessary, Symmetricom said.
