Airport Clocks and Time-distribution Systems

High reliability to within micro or nanoseconds and maximum availability are fundamental to the complex control centers in air travel. Time reference systems make flying safe and punctual. They supply the time to all the different systems throughout the airport, including time displays, talking clocks, flight monitoring, radar data and data exchanges.


Centralized systems for airport applications usually have a network consisting of a GPS synchronized main master clock, located in the main control room, and a number of sub-master clocks at various terminals. These master clocks then synchronize slave clocks and other IT systems in their environment, whereas the main master clock is connected with all sub-master clocks by means of the LAN/WAN and appropriate protocols (e.g. NTP). Air traffic control is also a crucial safety demand for people and monitoring instruments. With its Grandmaster clocks and NTP servers, MOBATIME delivers dependable time references for air traffic control monitoring systems.

NTP server or PTP grandmaster from MOBATIME guarantees that controlling and monitoring networks and the devices and instruments linked to these proceed in exact lockstep with one another.


MOBATIME can offer a variety of products and components for such applications and provides full customer support with regard to general system approach, depending on BoQ and customer specific requirements .
