GPS Week Rollover 6 April 2019
On Saturday 6 April at 23:59:42 UTC the GPS week count will rollover and be reset to zero. This may cause some GPS receivers to show database expiry messages or stop displaying some live services that are timestamped. GPS position data should not be affected.
Garmin have said that they have had no issue with their aviation units that they have tested, so long as the unit is running the latest software. Some of the other manufacturers have issued software updates to handle the week rollover. You are advised to check with your device manufacturer to see if it will be affected and, if so, if there is a fix.
