RTX’s Collins Aerospace Showcases Breakthrough Anti-Jam Navigation Technology
Collins Aerospace, an RTX business, has unveiled its latest advancement in anti-jam Assured Positioning, Navigation and Timing (APNT) technology during the U.S. Army’s All-Domain Persistent Experiment (ADPE) at White Sands Missile Range, New Mexico. The successful demonstration highlighted the company’s smallest and most portable APNT ground solution to date, underscoring Collins’ ability to deliver resilient navigation capabilities for modern and future battlefields.
Designed to operate in highly contested environments, the new system brings advanced navigation assurance into a compact, modular form that can be rapidly integrated across a wide range of military platforms.
Compact Design, Powerful Performance
At the heart of the demonstrtion was Collins Aerospace’s Compact Modular Open Systems Standards (CMOSS) Mounted Form Factor (CMFF) card. Despite its small footprint, the card delivers robust navigation resilience for ground vehicles, including robotic and autonomous systems that depend on precise positioning and timing to operate effectively.
Paired with an external antenna, the APNT solution demonstrated exceptional performance in denied and degraded GPS conditions. The system maintained accuracy and reliability even when exposed to intense electronic interference, proving that size does not compromise capability. Its modular architecture also enables faster upgrades and seamless integration into existing and future vehicle systems.
Resilient Navigation in Contested Environments
During the All-Domain Persistent Experiment, Collins’ APNT solution was tested against a dense environment of GPS jammers and spoofers—conditions that increasingly define modern conflict zones. Despite these challenges, the system consistently delivered assured navigation.
By leveraging Military-code GPS signals along with a combination of internal and external organic sensors, the solution fused multiple data sources in real time. This multi-sensor approach allowed ground vehicles to maintain accurate positioning and timing even when reliable GPS data was unavailable or deliberately disrupted.
“Our card provides highly precise navigation in contested environments and offers a scalable, cost-effective solution that is ready now for integration on a variety of platforms,” said Sandy Brown, vice president and general manager of Mission Critical Products at Collins Aerospace. “The smaller form factor enables faster mission customization while significantly improving situational awareness for operators.”
Supporting the Army’s Future Vision
The All-Domain Persistent Experiment serves as the U.S. Army’s open-air test environment for evaluating new technologies under Denied, Degraded, Intermittent, and Limited (DDIL) conditions. The initiative focuses on advancing capabilities across sensors, networks, data processing, positioning and timing, and electronic warfare—key pillars of the Army’s multi-domain operations strategy.
Collins Aerospace’s successful APNT demonstration aligns closely with these objectives, offering a practical and deployable solution to one of the military’s most pressing challenges: maintaining assured navigation in environments where GPS can no longer be taken for granted.
A Step Forward in Assured Navigation
As adversaries continue to invest heavily in electronic warfare and GPS denial technologies, assured navigation has become critical for mission success. Collins Aerospace’s compact APNT solution represents a significant step forward, combining advanced performance, modular design, and operational readiness.
With this demonstration, Collins reinforces its role as a key technology partner to the U.S. Army, delivering resilient, adaptable systems that help ensure freedom of maneuver and operational advantage in the most challenging environments.
