The rollover issue itself is caused by the fact that GPS systems count weeks using a ten-bit parameter. This means they start counting at week zero and reset when they hit week 1,024.
Is there a bug in the GPS system?
The bug isn’t disastrous and should only hit a small number of GPS devices, but for those impacted the results could be severe, resetting the receiver’s time and corrupting its location data. Only older devices are at risk, though, and if you’re just using a commercial device the fix is quite simple: just check that its software is up to date.

How often does a GPS rollover event occur?
The Global Positioning System (GPS) has its own date and time scale based on counting weeks, and seconds within a week. However, the field that contains the week number is limited to 1024 weeks, a GPS rollover event occurs when this counter reaches week 1023 and then rolls back to week 0. This happens about every 20 years.
The rollover issue itself is caused by the fact that GPS systems count weeks using a ten-bit parameter. This means they start counting at week zero and reset when they hit week 1,024.
When did the first reset on a GPS take place?
The rollover issue itself is caused by the fact that GPS systems count weeks using a ten-bit parameter. This means they start counting at week zero and reset when they hit week 1,024. The first count (or “GPS epoch”) started on January 6th, 1980, and the first reset took place on August 21st, 1999.
