Said, All of these were run out-of-the-box. So yes, auto-survey.
A fun experiment would be to set the position manually at different levels of [in]accuracy (say, +/- 1m, 3m, 10m, 30m, 100m) in lat, lon, and/or alt to graphically see the effect it makes on both 1PPS time offset and 10 MHz frequency stability. /tvb ----- Original Message ----- From: [EMAIL PROTECTED] To: [email protected] ; [EMAIL PROTECTED] Sent: Wednesday, February 13, 2008 10:50 AM Subject: Re: [time-nuts] GPS Locked and Unlocked Performance Comparison Hello Tom, on the measurements did you use Auto Survey on these receivers? Or did you give them a surveyed antenna position? Even good GPS's I have seen have a 3-5 feet height error or so from Auto Survey. I wonder how much better these units would perform if they get a well surveyed position set manually? Maybe their performance is so good already that it wouldn't make a difference in ADEV. bye, Said In a message dated 2/13/2008 04:47:46 Pacific Standard Time, [EMAIL PROTECTED] writes: > > Interesting thought.
