IT specialist CACI International's anti-drone detection system, SkyTracker, has been successfully tested for the first time in a commercial airport at Atlantic City International Airport (ACY) from 25 January to 2 February.
CACI COO and president of the US Operations John Mengucci said: "The results of testing under our PathFinder agreement with the FAA at Atlantic City International Airport demonstrate that CACI's proprietary system - SkyTracker - performed as designed.
"SkyTracker successfully identified, detected, and tracked UAS in flight, and precisely located drone ground operators - all without interfering with airport ground operations."
In October this year, the FAA and IT specialist CACI International teamed up to protect the airspace in and around airports from UAS.
The CACI partnership is part of the larger UAS Pathfinder Program, which the FAA announced in May this year.
The Pathfinder testing programme includes studying drone use in a wide range of industries, such as news gathering, agriculture and transport.
FAA Senior Advisor UAS Integration Marke Gibson said: "The explosive growth of the unmanned aircraft industry makes evaluating detection technologies an urgent priority.
"This research is totally aimed at keeping our skies safe, which is our number one mission."
CACI uses radio frequency sensors, which can identify frequencies used by unmanned aircrafts, placed at high, prominent locations close to an airport.
On detecting the frequencies, the system triangulates the signals and locates the exact location of both the UAS and its operator.
DHS Science and Technology deputy under secretary Robert Griffin said: "Working with the FAA, the DHS Science and Technology Directorate is proud to provide our expertise in testing and simulation of technologies to better address the safety and security challenges posed by unmanned aerial systems."
