Similar to the frenzy of the Y2K bug that hit in late 1999, Saturday could bring a comparable fiasco over the weekend.

When we travel by car, most of us will use our GPS for many reasons -- mostly to get to where we need to go, but also to tell us how long it will take to get there. But if you are planning on traveling this weekend, pay close attention to your GPS.

The GPS satellites that orbit Earth keep track of weeks, but they are only capable of holding 1,024 weeks of data. And we're hitting that threshold Saturday night when the satellites will reset to 0.

The Air Force, which manages these satellites, assures that the probability of having a real-world problem is small. But those whose systems are dependent on the satellites should monitor them closely.
