    Bris accuracy? 1
    From: Doug Royer
    Date: 2004 Nov 8, 13:09 -0800

    Let's not get our panties in a bunch over these results just yet.That is why
    I included the ? in the origonal title.
    I just wished to show the results of the sessions over the weekend.They
    appear to be getting closer to ther GPS coordinates the more I use the Bris.
    Perhaps I was lucky during the latest sessions.
    Perhaps my skill in useing this tool is getting better after useing it and
    getting comfortable in useing it.
    Perhaps my confidance level in the results are increasing after working LOPs
    the last few weekends.
    To many perhaps.Don't really know.
    
    This is what I do know:
    The 1st times I used this tool/procedure the results were in miles(between 8
    - 12 miles differance.)
    The next times I used it the results were within a couple of miles
    differance.
    
    For this past weekend's sessions LOPs the "cocked hat" area of the LOPs were
    fairly large.I used universal plotting sheets to get the LOPs reduced useing
    the GPS coordinates and a scientific calculator.The reduction program I used
    uses an AP.The plotting sheets were used and that pos was gained before I
    used the software to get the pos.
    Because the "cocked hat" area on the plotting sheets was big I drew where
    the center of that area was on the sheet and used that point as the final
    position.
    Useing the same raw numbers the LOP software gave the positions as around
    1,000yds with the same bearing on Sat. and around 800 yds with the bearing
    of 010* T for Sunday's position.
