GPS Rollover Mitigation by Integrasys

Madrid, March 11, 2019

At Integrasys, we have been working over the past years on a nanosecond switching solution to automatically switch the synchronization to an alternative synchronization path in case this primary synchronization clock suffers from any synchronization failure which will generate a dramatic service interruption over 48 hours.

Today, we are glad to announce that we have the solution to implement in minimum time for telco and broadcast customers to manage the most reliable communications in the coming GPS end of Week Rollover predicted on April 2019, where the GPS constellation will change the cycle and will reboot, stopping the GPS services over 48 hours for equipment already in operation.

In our company, we have been intensively working on the way to seamlessly synchronize clocks following Precision Time Protocol with 10MHz references, after working with CERN (European Organization for Nuclear Research) in the nanosecond synchronization project. For synchronizing experiments in large distance areas, Switzerland and Italy.

Nuclear research demands the highest synchronization accuracy and lowest jitter, which not even GPS complies with; therefore, Integrasys worked with CERN to enable this capability and fulfil the need. The work done under this project, have been extracting to software which enables an automated switch to the most accurate timing source available in the event GPS is interrupted due to the scheduled rollover on April 6, 2019.

Additionally, to the software solution, Integrasys offers simulation tests for transmission chains where we simulate the rollover and certify that the equipment installed is going to lose the synchronization or not over the rollover.

To summarise, Integrasys has started with numerous projects to prevent the event with its state-ofthe-art nanosecond switching and RF degradation mitigation which could drive in a massive revenueloose to teleports, TV channels, Terrestrial networks and satellite networks.
