Your GPS is not synced - the number after the "E" should be 1 2 or 3 (see http://www.gpsinformation.org/dale/nmea.htm#GGA) My guess it's is either not seeing the sky clearly (indoors?) or it's not had time to get the current almanac (it can take 20 mins for the first startup before hte GPS starts seeing val;id data). Good data will look something like this: ntpq> cl assID=0 status=0000 clk_okay, last_clk_okay, device="NMEA GPS Clock", timecode="$GPGGA,211257,3751.0948,N,12229.2971,W,2,06,1.4,185.4,M,-27.9,M,,*79", poll=9517, noreply=0, badformat=0, baddata=0, fudgetime1=0.000, stratum=0, refid=GPS, flags=4 ntpq> 2 = DGPS 06 = sats in view 1.4 = Horizontal dilution of position You have no stats in view and fix quality "0" = invalid.
