The NMEA timing messages arrive about 90mS after the PPS second and that doesn't vary more than about +/- 10mS. Currently showing 14 GPS and 9 GLONASS satellites and the PPS jitter is 21nS. The weather has been too bad today to put it into the outdoor cabinet where it can get a good view of the sky. As soon as I open the door it would fill with snow and the blast of cold air would upset the sample rates of the VLF sound cards. The weather here doesn't look good for days. I've not yet activated the survey-in and fixed position mode. How good will it be then! I'll just have to try it with the antenna on the office window ledge. -- Paul Nicholson --
