Re: GPS week rollover
I think the chance we're still using the GPS satellites in 3238 is quite low, especially as we already have three other options that work everywhere and don't have such a restricted version. By then, those satellites won't work if they're still in orbit at all. Even if we didn't ever redesign them, one problem that affects people in 3238 beats problems for people in 1999, 2019, apparently also offsets of those years, and almost certainly in 2038. The 1265-year option is only if they wanted to keep their design--they also had the option to report dates in a more configurable way.
