Application Note, White Papers, Case Studies & Presentations

The Communications Industry is just one of many industries that have serious concerns over Cyber security issues related to hackers and possible damage to infrastructure from terrorist activities. One of the components of Cyber Security that is a critical piece of the communications infrastructure is GNSS vulnerability. GNSS (Global Navigation Satellite System) technology includes GPS (Global Positioning System, United States owned and operated) along with Global Satellite Navigation Systems operated by China (Beidu) and Russia (Glonass). These Global Navigation Systems are used to obtain an accurate position or location but are also used to deliver accurate timing that is distributed in communications networks for a variety of applications.

A major telecom operator's timing was being disrupted intermittently

Case Study

Timing dependent applications rely on their clocks being correct within the set tolerances required by that technology

Whitepaper

Worldwide Financial Institutions seek to offer the fastest trading speeds possible to support high-frequency trading and comply to MIFID II

Case Study

Practical issues to overcome when performing audits of time distribution systems to financial trading regulations such as MiFID II and FINRAR

Presentation

GNSS signals are used extensively in many Positioning Navigation & Timing applications necessitating fixed antenna installations

Application Note

Time for Telecoms - presentation to Wireless Heritage SIG

Presentation

A sync system was reporting loss of signal and poor quality timing from the upstream GPS receiver due to GPS jamming

Case Study

Sync Consultancy and Testing Services - Chronos has been actively engaged in synchronisation and timing for over 30 years

Application Note

LD4 Data Centre had been experiencing interference to the GPS L1 signal for several months due to a rogue antenna

Case Study

As demand for bandwidth increases exponentially, wireless backhaul networks have rapidly shifted from circuit switched to packet switched
