Radio Becomes an Aid to Navigation
Among the many innovations that NIST contributed to navigation was a radio
direction finder (RDF), a special antenna that determined the direction of
radio transmissions. The original RDF was made by an Italian team, but NIST
researchers patented an improved design, built in 1916. It served as a
prototype for the U.S. Navy and was used widely to pinpoint the positions of
enemy forces during World War I.
