Dansville FAA Radar Site (1959-Active) - A Federal Aviation Administration (FAA) Long Range Radar (LRR) site first established in 1959 near Dansville, Livingston County, New York. The site is used to identify and track military and civilian aircraft movements within a 200-mile radius and to provide air-ground radio communication with those aircraft. Assigned a SAGE System ID of Z-309, a JSS ID of J-56, and an FAA ID of DSV. Active FAA Radar Site.


This site became an FAA radar site in 1959, furnishing radar track data to the FAA ARTCCs and later to USAF Direction Centers. Located on a 1.7-acre site belonging to the U.S. government at 7903 Story Road, Springwater, New York. The initial FAA ARSR-1 search radar was eventually upgraded to an ARSR-1E configuration that remained in operation until it was modified to become a CARSR radar with a 7172 antenna as of 24 May 2012.

Originally equipped with an FYQ-49 and "data tied" to the JSS System. By 1990 the site was equipped with a ARSR-1E search radar and a CD-2A Common Digitizer. The Dansville CD-2A was scheduled to receive an upgrade kit to implement three level weather data processing in September 1992.


The nationwide replacement program converting FAA legacy radar systems to the CARSR radar configuration was completed by 17 Aug 2015 and Dansville FAA Radar Site was a part of that program. Legacy FAA radars underwent a Service Life Extension Program (SLEP) that replaced key components in the vintage ARSR-1, ARSR-2, FPS-20, FPS-66 and FPS-67 radars. The CARSR program replaced legacy klystron radar transmitters with a solid-state transmitter as well as renovating the radar receiver and signal processor. The CARSR modification also included common digitizer functionality making a separate common digitizer unnecessary. The Dansville FAA Radar Site is now operating with the CARSR radar.

The radar site data is now available to the USAF/NORAD Battle Control System-Fixed (BCS-F) operations centers (EADS & WADS) as well as the FAA New York ARTCC (ZNY) and adjacent ARTCCs. Other federal agencies have access to the data under the Homeland Security umbrella.
