Check your Driver Terminal’s status

Similar to the Millennium bug, the GPS Week Number Roll Over Issue occurs when the GPS calendar resets to 0. The next reset is due on April 6th 2019. After the roll over, the performance of some Driver Terminals will be impacted. The majority of our TomTom products will not be affected by this issue, but we want to ensure that you are well-informed on the potential impact. Hence, what does this mean for you? It’s time to check your Driver Terminal.

Depending on your fleet size, you have two different options to check its status. Get started below.

What is the GPS Week Number Roll Over and why does it matter to you?

The GPS Week Number Roll Over (WNRO) occurs every 19 years, with the next roll over taking place on 6 April 2019. Similar to odometers in older cars rolling over from 99,999 km to 0, the GPS WNRO is the resetting of the GPS calendar back to 0.

When the calendar resets, it causes a miscommunication between GPS satellites and GPS receiver chips. As a result, some chips in Driver Terminals will lose the ability to process certain functions.
