You'd be using the same NTP software in either case. The difference is it you were to add a GPS reference clock to the current setup. Even with GPS you's till want to keep the internet based reference clocks. Currently your PC clock might be accurate that the few milliseconds level. Adding a GPS receiver into the mix will improve accuracy to the tens of microseconds level. You'd gain abut two orders of magnitude over the current setup. Do you need this? I can think of uses for a highly accurate clock in amateur radio. Perhaps you are measuring propagation delay. Doing this 100 times more accurately might be helpful. On the other hand maybe you only need log files time stamps to be with a second or so of correct? When I got into this may application was pointing telescopes and measuring the light from variable stars. Usually you can start with you application and work backwards to place a requirement on time accuracy On the other hand this is a "time nuts" list and some people here just want the BEST they can get. I'm not a fan of Meinberg because of the way they market freely available software. -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
