What is CORS?
CORS is the acronym for a GPS “Continuously Operating Reference Station”. Originally established in the United States by the U.S. Coast Guard to provide a precise positional reference for shipboard navigators, the system has become popular with Land Surveyors, Engineers, and with Geologists that research the movements of the Earths continental plates. Congress asked for a solution to improve the way reliable elevations and heights were being determined in the United States, and the National Geodetic Survey responded with a proposal for a Height Modernization Program to utilize GPS CORS sites as the basic elevation reference tool for the 21st century. Around the same time, the U.S.S.R. fell with the Iron Curtain, and the U.S. Department of Defense began to de-classify the secret gravity model of the Earth that had been used for targeting Inter Continental Ballistic Missiles. That secret gravity model is now available to the general public, and it is one of the key components of the Nati
