Leica Zeno

Preparing for Leap Second 2016

Leap Second Zeno
Leica Zeno

With the defined SW and ME FW version (3.3 for Zeno 5; 1.13(46) for Zeno 10 and Zeno 15; 6.403 for Zeno 20, CS25, CS35 plus, CS25 GNSS plus ad GG02), the tracking behavior for GPS and Galileo of all Leica Zeno devices will not be affected over the leap second change. GLONASS tracking will lose lock briefly and recover a few seconds later.

If a Leica Zeno device is used after the leap second switch, the receiver will have trouble tracking GLONASS signals until a new almanac is downloaded, which can take up to a few minutes. A receiver reset will resolve the problem faster and enable users to track GLONASS satellites again.
