From what information are you assuming these will run for centuries? Most sats have a design life of like 10 to 25 years max. Also keep in mind that station-keeping and correction data is mandatory to keep the accuracy in check. I think I read somewhere that after 180 days of un-corrected drift the GPS would be able to get you within a few km of your target - not meters/feet.
- willis936 7y agoI was told by someone who follows theses things more closely than me that block III GPS would have an inter satellite network that could share clock information independently of ground control. While looking into it the closest I could find was references to OCX, which is ground based controls. So maybe we're not there yet idk.
