Critical Update: Leap Second Firmware Update

Critical Update: Leap Second Firmware Update

TopCon customers using a GNSS receiver; we would like to inform you of a critical firmware update to your GNSS receiver. The systems routinely correct for a Leap Second event that impacts all GNSS products around the world. The next almanac update for Leap Second is anticipated in July. As a result the GNSS receivers need to be updated to address the Leap Second so that they perform optimally.

Topcon has issued communication that all GNSS receivers be updated to the latest firmware available so that you don't experience any loss in productivity. To check if your GNSS receiver is up to date visit www.myTopcon.com. Once you log in and register your product, you will be able to download the latest firmware and update your receiver.

What is a Leap Second (LS) ?

A leap second is an occasional one-second adjustment to Coordinated Universal Time (UTC) to keep its time of day close to the astronomical time (UT1). Leap seconds are added to our clocks to compensate for the Earth's slowing rotation. The International Earth Rotation and Reference System Service (IERS) in Paris, France observes the Earth's rotation and compares it to the atomic time. Since this system of correction was implemented in 1972, 27 leap seconds have been inserted, the most recent on December 31, 2016 at 23:59:60 UTC (2016 LS Event).
