Orolia's high-performance Time & Frequency equipment is essential to modern information systems. Typical applications include:
 Navigation & Space : atomic clocks on board navigation satellites (GPS, Galileo, Compass, Glonass, IRNSS) are used to produce signals received by GPS receivers to determine position anywhere on earth. To get very precise data, these signals must be perfectly synchronized. The extremely precise measurement of time on board each satellite is fundamental to the operation of global positioning. Some interplanetary observation satellites also have high-precision clocks on board.
Defense & Security : Synchronization is a vital requirement for military operations. The military forces are transforming their capabilities based on network-centric warfare, envisioned as a global information grid of secure, interconnected, and interoperable networks. Distribution of precise time over today's IP-based networks enables true synchronization of field operations, including centralized command and control systems. Precise and synchronized time on data logs, discrete clients, and trasaction is an imperative in conducting data forensics to support anti-hacking and disaster recovery efforts.
When extremely accurate timing is required, atomic clocks are used to secure military telecommunications and to synchronize the different elements of modern warfare (military communications satellites, "drones", aircraft, missiles, submarines, navigation centers, electronic war systems, etc.).
Telecom & Broadcast : time from precise clocks and their synchronization allow data to be generated and received anywhere on the network at a constant rate. Without this precision, broadcast and reception rates would be different, data would be lost and service quality would be affected. Clocks and synchronization systems are critical elements for keeping wireline telecom networks (optical backbone, and access and metropolitan networks), and wireless telecom networks (GSM, CDMA, 3G, Wimax.) in good working order. They assure top quality service required by telecommunication operators as well as the quality of broadcasting networks, Digital Terrestrial Broadcasting and mobile TV in particular.
