L3Harris Advances GPS Protection With Anti-Jam and Anti-Spoofing Technology
L3Harris Technologies is advancing its military navigation capabilities with TruNav AJ, a GPS protection system designed to counter both signal jamming and spoofing in increasingly contested operating environments.
Traditional GPS protection has focused largely on preventing jamming, which disrupts access to positioning, navigation and timing signals. Spoofing creates a different threat by transmitting false signals that can provide military systems with incorrect positioning or timing information. L3Harris says modern navigation systems increasingly need protection against both threats.
TruNav AJ combines multichannel digital antenna electronics with anti-jam, anti-spoofing and jammer situational-awareness capabilities. When paired with the company’s TruTrak-M military GPS receiver, the system can perform anti-jam-assisted anti-spoofing while detecting and mitigating surrounding jamming threats.
L3Harris has also designed the technology for integration across military platforms with different size, weight, power and cost requirements. The company supports the navigation portfolio with modeling, simulation, testing and systems engineering capabilities.
The technology reflects the growing importance of resilient positioning and navigation as electronic warfare increasingly targets the GPS signals used by aircraft and other military systems.
