For decades, protecting military GPS largely meant ensuring a signal could get through. Today, the challenge is more complicated. As threats to GPS become more complex, militaries must be prepared for both disruption and manipulation of critical information.
Jamming can interfere with GPS signals and deny access to crucial positioning, navigation and timing data. Spoofing presents a different challenge by introducing false signals that can cause a system to receive inaccurate positioning or timing information. For airmen operating in contested environments, protecting GPS means accounting for both.
The result is a broader mission for GPS protection. Anti-jam capability remains critical, but today's navigation technology must also protect against spoofing and provide greater awareness of jamming threats in the surrounding environment. The challenge isn't simply keeping a signal available. It's protecting the navigation information behind it.
Disruption and Manipulation
L3Harris' TruNav navigation portfolio addresses this broader challenge with modernized GPS and enhanced anti-spoofing and anti-jam solutions across different size, weight, power and cost requirements.
One of those solutions, TruNav AJ, brings multiple layers of protection together. The multichannel digital antenna electronics, when paired with the L3Harris TruTrak-M military GPS receiver, can perform anti-jam-aided anti-spoofing while also providing advanced detection and mitigation of jamming threats.
For military users, these capabilities offer protection against different threats to the GPS information their systems depend on, while providing greater awareness when jamming is present.
Adding Awareness to the Equation
Awareness is an important part of TruNav AJ's approach. Its advanced jammer situational awareness supports improved detection and mitigation of jamming threats, complementing the system's anti-jam protection.
In military aviation, GPS technology doesn't operate in an uncontested environment. Airmen and the systems supporting them may have to rely on navigation information even as the signals around them are challenged.
The objective is broader GPS protection built for a threat environment that includes more than jamming. TruNav AJ extends protection beyond interference alone. Rather than treating each threat separately, the system brings those capabilities together in a single solution. That is what it means to go beyond anti-jam.
From Advanced Technology to Usable Capability
Developing this protection is only part of the job. It also has to work within the systems that need it.
Military platforms have real constraints. Space, weight, power and cost all influence what can be integrated, along with schedule and performance requirements. New capability has to account for those realities without introducing unnecessary complexity.
TruNav AJ is designed with a streamlined setup for seamless integration. The broader TruNav portfolio spans a range of size, weight, power and cost points, giving customers options to address different system requirements.
Integration also goes beyond the hardware itself.
L3Harris brings end-to-end modeling and simulation, testing and systems engineering capabilities to its navigation portfolio. This approach helps customers consider navigation as part of the larger system while working toward cost, schedule and performance goals across the lifecycle.
Beyond Anti-Jam
GPS is more crucial than ever for military operations, but the threats challenging it are evolving. For airmen, that means GPS protection must address a range of challenges. Anti-jam capability remains essential, while anti-spoofing technology and greater awareness of jamming threats add layers of protection for operations in contested environments.
L3Harris’ TruNav AJ brings these capabilities together in a single multichannel digital antenna electronics system. In a contested environment, knowing where you are is only part of the challenge. Protecting the information that gets you there is just as important.
