Hi,
I played with my GPS. It is a Rikaline USB GPS module for a laptop
computer and has the Sirf II receiver. I noticed the resulting path that
I recorded didn't look like I expected. It was close, but looked sloppy.
So I stuck it to a piece of steel sheet, about 8"x9" and ran it again.
(This is one of those that has a magnet to stick to the top of your
car.) It worked much better the second time.
Does a GPS receiver prefer a ground plane? Or did I just have a better
fix the second time? If a ground plane is preferred, does anybody know
the recommended size of the plane?
