Can't find your serial number? What is the GPS Week Number Rollover?

What is the GPS Week Number Rollover?

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

When the calendar resets, it can cause a miscommunication between GPS satellites and GPS receiver chips. As a result, some chips in navigation devices will lose the ability to process certain functions.

What does this mean for you? It's time to check your navigation device. Depending on your device, you may need to update or upgrade.
