I was just wondering what, in everybody's experience, are the suspects for multi-path? I am working in a stockpile area that is essentially koalin piles placed on a pad composed of koalin. Everything except for me is some shade of white and reflects sunlight like crazy. With the exception of my problem immediately below, I haven't noticed any problems measuring stockpiles in other areas.
Thanks,

Here is a question for Mr. G. would the color of an object effect the reflectivity of GPS signals? Would a "slick" surface cause more problems than a rough surface?
