Fun fact: GPS uses 10 bits to store the week. That means it runs out... oh heck – April 6, 2019

Week count?

What purpose does a week count actually serve in computing a position? I'm old enough to remember pre-GPS times[1], and we already had 32-bit timestamps. Is that final week purely coincidental with other silly traditions and tragically stupid one-off events, or might this be made a scapegoat for something?

[1] In fact I even spent some time in the 1980s working on a pre-GPS tracking and positioning system for vehicles, where fitting the entire onboard software into a 128k ROM was one of the issues we had to deal with.
