Harris Corporation was an American technology company, defense contractor, and information technology services provider that produced wireless equipment, tactical radios, electronic systems, night vision equipment and both terrestrial and spaceborne antennas for use in the government, defense, emergency service, and commercial sectors.

[citation needed] In 1959, they acquired microwave technology company PRD Electronics, also headquartered in Brooklyn, New York.

[citation needed] In 1967, they merged with Radiation Incorporated (formed in 1950) of Melbourne, Florida, a developer of antenna, integrated circuit and modem technology used in the space race.

[12] In 1983, Harris acquired Lanier Business Products, Inc., a dictation, word processing and computer company based in Atlanta, Georgia.

[14] Harris Corporation developed a Hand Held Computer for use during the address canvassing portion of the 2010 United States Census.

Harris received $225M for the transaction, exactly half of what it paid seven years earlier for Leitch Technology, its final acquisition for the Broadcast division.

[23] In October 2018 Harris announced an all-stock "merger of equals" with New York-based L3 Technologies, to be closed (subject to approvals) in mid-2019.

[26][27] The Harris Communication Systems segment served markets in tactical and airborne radios, night vision technology and defense and public safety networks.

Electronic Systems (ES) division provided the "ALQ-214" radio frequency jamming equipment for the U.S. Navy's F/A-18 Hornet aircraft.

[29] The Harris Space and Intelligence Systems segment, formed when Harris purchased Exelis,[30] provides capabilities in Earth observation, weather, geospatial monitoring, space protection and intelligence, including sensors and payloads, ground processing and information analytics.

[31] Harris Corporation produced multiple cell-site simulator products, such as the StingRay and Hailstorm phone trackers (see table below); These masquerade as legitimate cellphone towers duping mobile devices to connect to them instead of real cellular networks, so all wireless voice and data traffic originating in a given area are intercepted by the systems, enabling Stingray operators to conduct mass surveillance and triangulate the position of mobile devices.

The American Civil Liberties Union (ACLU) says at least 53 law enforcement agencies in 21 states, use this or similar devices.

[35] These platforms are controversial[36][37] as they surveil communications of all mobile devices in their vicinity, including those of individuals not suspected of any crimes.

[38][39] Harris have been criticized by civil rights advocates for requiring local municipalities, police and state governments to enter into non-disclosure agreements (NDA)[40] and to conceal usage of these platforms from citizens and the courts.
