Synchronization systems enable the synchronization of equipment used in communication networks and critical systems (computer networks, telecommunications networks, satellites, defense/fight systems). They also allow time stamping of events occurring on these networks with the utmost reliability and traceability. Here are some of Spectracom products developed and refined for over 20 years.

GPS - synchronized clocks for wireless networks and broadcasting

These devices use a synchronization method based on the very stable time signal delivered by the constellation of navigation satellites. These satellites continuously broadcast high-precision time information with an accuracy better than a billionth of a second. These products are composed of a GPS receiver, an oscillator (quartz or rubidium) and a GPS signal's servo-control system. It is a clock synchronized to GPS atomic clocks. However, thanks to the core stability of the local clock, the time-frequency signals will remain accurate and stable even if the GPS signal is unavailable.

One specialty - in which Spectracom is a worldwide leader - is the development of clocks allowing time & frequency synchronization of broadcasting networks (DVB-T, DVB-H, DVB-SH, T-DMB.). Depending on the specific application and on its clients' positioning in the value chain (operators/components manufacturers), Orolia develops rugged field-deployable systems or OEM modules that are easily integrated in component manufacturers' products.

NetClock Time Servers

NetClock systems are based on GPS technology to offer official time anyhere on earth. NetClocks support virtually every time protocol to synchronize time-sensitive devices including network elements, facilities clocks, applications software, patient monitoring systems, medical devices, access control systems, voice and video recorders, and more.



Synchronization Supply Units (SSU)

SSU are used as a time reference for wireline telecom networks or dedicated military applications. These systems, with several redundancy levels and the utmost reliability, are used to filter the input frequency signal and to broadcast it over an expandable number of outputs in order to locally synchronize other network elements. Moreover, Orolia develops specific systems for delivering high-precision time-frequency signals to remote locations.


Complex custom-built systems

These include clocks, servo-control and redundancy systems for dedicated applications, in the military field in particular : primary time reference for nuclear attack submarines, time and synchronization reference to test ballistic or tactical missiles' path control, synchronization of the telecommunication system used by the President of the French Republic to launch the nuclear fire, synchronization of French Air Force army's systems and equipment, and the Swiss Army's jamming and electronic war systems.
