Similar to the Millennium bug, the GPS Week Number Roll Over occurs when the GPS calendar resets to 0. The next reset is due on April 6th 2019. What does this mean for you? It's time to check your Driver Terminal. Depending on your device, you may need to perform a software update, check the settings of your device or upgrade.
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.
