Join the dedication ceremony at Turner Farm on Saturday, June 24th at 10am in the park. The Virginia Board of Historic Resources has designated a highway marker to recognize this site not only as a former Nike missile site, but as an important satellite tracking facility of the U.S. Army Map Service. The Marker states that "This tracking system contributed fundamentally to the Global Positioning System (GPS). The data gathered here enabled geospatial scientists to establish precise geographical reference points on the Earth’s surface and to refine their estimates of the Earth’s true shape and variations in its gravity field."
Local and state officials, members of the community and former employees of the U.S. Army Map Service and Defense Mapping Agency will be in attendance. The event is sponsored by the Fairfax County Park Authority and the Analemma Society.
Turner Farm is located at 925 Springvale Road, Great Falls, VA. For more information about the ceremony, please contact the Public Information Office at 703-324-8662 or via This email address is being protected from spambots. You need JavaScript enabled to view it..
