GPS devices - Is yours compatible for the GPS WNRO on April 6, 2019?

What is GPS Week Number Rollover (WNRO)?
WNRO is an event with the potential to impact GPS receivers worldwide.

What exactly is happening?
A GPS signal contains a time element that tracks weeks. This number is encoded as a 10-bit field in each message. A maximum of 1,024 weeks can go by before GPS receivers need to reset the week number and start counting again from zero. This period is called an epoch, and we’re about to rollover from one epoch to the next.

When is GPS Week Number Rollover?
Our current epoch started on August 1, 1999 and is due to end on April 6, 2019, which is when the 2nd rollover takes place.

What could potentially happen?
It’s possible the rollover could create some GPS or timing errors.

Will this only relate older GPS systems?
No. All GPS systems have the potential to be affected by WNRO.
