The 18 numbers are typical of my experience with various NMEA serial devices. I've found one exception -- the JL Fury. These are typical values: o127.127.22.0 .GPPS. 0 l 5 8 377 0.000 0.001 0.002 *127.127.20.0 .FURY. 0 l 4 8 377 0.000 -0.042 0.023 The JL Firefly II is about an order of magnitude worse than the Fury so it's not simply that they're GPSDOs from JL. Still better than your typical serial device but nothing to write home about. _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
