Isn't a major problem with CDMA-based sources that the networks they depend on are getting shut down?
Domestically, yes. Not only are you dependant on Sprint if you go that route (Verizon is already pulling the plug on CDMA this year.), it was never any better than +/- 10 ms or so. You can get that via NTP pointed at the Internet. At best, all you were doing with CDMA was relying on a cell site's GPS receiver and holdover characteristics -- which were totally opaque to you. At least you can monitor NTP. --msa
