NavList:

pictures of my computer solution and plot.  It's fairly messy.  Suprisingly the moon was my best line.

 

You can see the letters jumbled in the middle of the plot.  Those are the retarded AP's of the different body from the GPS fix which was the AP for the sight.  You will see that I don't retard the lines, just the AP and plot the intercept from these new AP's.

 

One of my biggest problems is that I shoot so close to the fix time that the distance to retard was at most about 3 miles, and often under 1nm, and that is hard to plot on such a small scale.  It would be even harder on a universal plotting sheet.  I think that my graphical errors in plotting are the biggest source of my position error on a regular basis.  Of course those with better drafting skills then I have can certainly reduce this error greatly.
