If you want to test the accuracy of your gps receiver, then go to the following site. http://www.ngs.noaa.gov/datasheet.html This will tell you the location of benchmarks found in the usa, and for certain parts of canada. For the rest of canada, you have to pay to get the benchmark info. http://www.geod.nrcan.gc.ca/products/html-public/GSDinfo/English/factsheets/about_reference_networks.html In a few years we will get to use gps receivers that will recive three frequencies, not the current one. Even more accuracy!. Kevin --- "MALEY, PAUL D.
