A few months ago one of the satellites was still broadcasting while it was down for routine maintenance, reporting some time that was off by a third of the distance to the sun.
There are enough weird GPS errors that I'd hope they have a backup plan already.
- tjohns 9y agoWouldn't the GPS ephemeris/almanac data would still list the satellite as inop, even if it's still transmitting?
- jtolmar 9y agoThey did, so actual GPS location chips weren't thrown off. But apparently there are GPS-based clocks out there that don't actually bother to read the almanac. (I'm a few layers removed from the error report where I saw this so I don't really know the details.)
