A leap second will occur on the 30th June and Trimble Infrastructure has made every effort to ensure that Trimble receivers and software will work seamlessly through the added second.
Announced by the International Earth Rotation and Reference Systems Service (IERS), a leap second is an adjustment to Coordinated Universal Time (UTC) to account for the slowing rotation of the earth. Leap seconds were introduced in 1972 to simplify adjustments to UTC, one of the successors to Greenwich Mean Time and the primary regulator of world time. Leap seconds are only applied as needed and since their inception we have had 25 leap seconds. The last leap second, in 2012, caused problems on the internet and web based systems, with some web servers unable to process the extra second.
What do you need to do?
Ensure that your Trimble hardware has the latest firmware and that your software is upgraded to the latest updates and patches.
GNSS receivers operate at their best performance if they are on the latest firmware. If you are under maintenance or have a receiver less than 12 months old please check the software version and update it if necessary.
If you do experience difficulties on the morning of Wednesday 1st July, best practice would be to reset your receiver. On most models this is by turning the receiver off, then holding down the ‘on button’ for just over 30 seconds on start-up. The receiver may then take a few minutes to reacquire satellites.
For more information please see the Leap Second Support Note to review how each version of Survey GNSS firmware will handle the introduction of the UTC leap second to the GNSS satellite constellations.
We would also like to take this opportunity to remind you to check your receiver platforms to ensure they are running the most current firmware available from the respective manufacturer.
Contact your local UPG office if you need any assistance in update your software or firmware.
