The 2015 Leap Second – LabSat Scenarios Now Available

Posted in News

The 2015 leap second took place on Tuesday at 23:59:60 UTC.

Were you ready?

This event occurs every couple of years and can have an impact on systems that require a precise time signal. As we discovered earlier this year, some GNSS receivers may have had difficulty in dealing with the addition of this leap second due to the differing ‘day numbering’ between satellite constellations: GPS and Galileo use 1-7 as week day numbers whereas the Chinese BeiDou network uses 1-6.

Do you need to replicate the Leap Second?

Do you have a GNSS-enabled device in development? With the LabSat 3 Simulator you can reliably test your products on the bench to see how they cope with events such as the leap second, alongside standard issues such as multipath and signal obscuration.

Recordings of the leap second from the three main constellations are now available for use with a LabSat 3.


We have recorded this event this as single channel only file for GPS, GLONASS, and BeiDou; and as a triple constellation file of all three.

The scenarios are approximately thirty minutes long, and are free of charge.
