You have an unused network. For about 20km between work and ISP it is more like 100ms peak to peak. (2Mb/s 1:1) > receiver would be better, especially if it know its location.

If it has to diiscover its It's going to take at least 30 seconds to do that, as it will need the detailed emphemeris data and that takes 30 seconds to transmit (it might well pick the strongest signal and try to read the coarse ephemeris data first; I'm not sure if that fits in the 30 seconds. _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
