![]() I have some other GPS receivers that may be affected by this - they are old Magellan Sportrac units that I use for hiking. Somebody just got sloppy back in the earlier years there - lack of homework done, I guess. More recent TomTom devices, for example, are prepared for it already. Most GPS devices won't be impacted by this problem since most code was written more recently and will handle this special case. Then again, there were only a small handful of commercial and military GPS manufacturers back in 1999. ![]() So suddenly the date for impacted units will show up as back in 1999 when we reach 4/6/19.Īs this same thing had already happened before in 1999, it should have been anticipated, but evidently was not. The next time the 10 bit counter will reach week 1023 and rollover to 0 is on April 6, 2019. The 10 bit weeks counter ran out and rolled over to 0 again on Augand has been counting 1 for each year since. The event has to do with a rollover in a count of weeks (part of the GPS time information) where the number of bits forces a rollover from week 1023 to week 0 instead of 1024.
