Not sure why you were downvoted; this is my understanding also. Could someone with deeper GPS knowledge chime in?

- ahelwer 7y agoIf you read my post, it ends with "...and it's likely some will see a software failure this weekend" - of course a properly-coded GPS device will be fine but the likelihood of the many thousands of different types of GPS devices out there all gracefully handling an event that happens once every two decades is basically zero.
- rightbyte 7y agoSatelite constellation (position in the sky) is date stamped right? If the internal clock date doesn't match the received the updates may be ignored.
- makomk 7y agoThe satellite position updates use essentially the same time format as the rest of GPS, as I understand it. So the problem comes when some GPS receivers try and use the latest information but base their calculations on an erroneous belief it's now 1024 weeks into the past, causing them to fail to find satellites.
