Yes (Google NTP Beaglebone or NTP Raspberry Pi I have both) although since that almost certainly means GPS derived time you typically use a PPS signal to get acceptable jitter. The JL Fury NMEA stream will do 10s of microseconds of offset and jitter but I don't believe that's common, certainly not in any of the other NMEA sources I used. Another low cost/low power approach is a Laureline appliance but they don't run NTP -- they simply respond to time queries with GPS derived responses. _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
