Lockheed Martin [LMT] last month said it has acquired PercepTek, Inc., a developer of autonomous software technologies used in navigation for unmanned ground vehicles and aircraft systems, and automated persistent surveillance for security applications.

Terms of the deal were not disclosed. Lockheed Martin said the acquisition will not be material to its financial results.

“Lockheed Martin already is a leader in autonomous vehicles, with systems operating in the land, sea, air and space domains,” Christopher Kubasik, executive vice president of Lockheed Martin’s Electronic Systems Business Area, said in a statement. “The acquisition of PercepTek will strengthen our capabilities in unmanned systems and surveillance, allowing us to provide a broader portfolio of solutions to our customers.”

PercepTek’s customers include the Army’s Aviation Applied Technology Directorate and Tank-Automotive Armaments Command, the Defense Advanced Research Projects Agency, and the Air Force. The company also serves the commercial automotive, agriculture and mining markets.

Colorado-based PercepTek will become part of Lockheed Martin Missiles and Fire Control division.
