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 6, 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 Rollover (WNRO) occurs every 19 years, with the next rollover 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.
