> GPS absolutely requires up to date orbital parameters for each satellite it's using. Who is going to constantly ping the server for up to date ephemerides every 30 seconds when the GPS chip can give you them for free? I agree with the general point you're making, but this is wrong. The main benefit to getting ephemerides data is to get reasonably up-to-date orbital paths, you don't need it every 30 seconds. The GPS device needs to project future paths anyway up to 30 seconds into the future even in the best-case scenario, so it's already making predictions based on past data. The devices in question were already caching this data for days or weeks. It only became a problem when the server-side data was wrongly generated for whatever reason.
