Here is a Google Earth file that contains locations and basic information about all of the National Geodetic Survey (NGS) Continuously Operating Reference Stations CORS. Data was downloaded from ngs.noaa.gov and then merged together to create one large file. It was then symbolized based on the sampling rate of the GPS receiver at the CORS location (e.g. 1s, 5s, 15s, 30s etc.) and each point contains basic information and a link to the full data sheet.
This little file has been pretty helpful with planning GPS control networks on many of my LIDAR projects throughout the US.
