GPS Week Number Issue

GPS Week Number Issue

You may have recently been contacted by us regarding potential impacts to location accuracy during 9-1-1 calls on your device.

This is due to the GPS Week Number Rollover (WNRO) event, which will occur as early as April 6, 2019. The Week Number Rollover refers to the limitation of values in the GPS message format counter. After the counter reaches the 1024th week, it will reset to zero, which is what will occur as early as April 6, 2019.

Properly configured devices should not be affected. However, some hardware chipsets incorrectly handle the April 6, 2019, rollover. Because GPS Time is used for user location determination, an improperly configured device may result in improper location information associated with 9-1-1 calls.

In addition to location accuracy during 9-1-1 calls, device applications that depend on GPS location may also be impacted.

Most devices are properly configured. However, the following devices are known to be affected beginning April 6, 2019. Certain devices have a software patch available to correct the issue. If no patch is available, you can contact us at 1 866 841 7004 or visit an Xplore Mobile store to understand your options. The following list provides the known impacts and possible resolution for known affected devices that you may have brought with you when coming to Xplore Mobile:
