To sync to a second any gps receiver will do. The Garmin 18PC or USB will do and will get you down to about 5ms accuracy with some tuning. The PPS on the 18LVC will do 1000 times better ( again $50-100 range) On the 18PC you have to supply the, I think it is 12 V from somewhere else. On the USB it will supply its own voltage if I read correctly. >Thanks. >Diego >On Fri, Jan 9, 2009 at 1:18 PM, Richard B.
