Reference time clock protects against 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. The system is also designed to meet the stringent new ITU-T Recommendation G.8272.1, which requires accuracy to within 30 ns or better when verified against a time standard such as UTC.
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. The 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 a report from Research and Markets 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.
