DRAGN™
Dynamic Resilient Assured Guidance & Navigation
Modern operational environments are evolving faster than ever. Success on the frontlines depends on the ability to know precisely where you are, where you are headed, and to trust that information no matter the conditions.
While large platforms like fighter jets and helicopters are equipped with advanced Inertial Navigation Systems (INS) fused with GNSS, UAVs have traditionally faced tough constraints on size, weight, power consumption, and cost, forcing them to rely almost exclusively on GNSS.
This dependence on GNSS reduces their resilience to interference, making mission success vulnerable, particularly when operating on the front line or in contested environments where jamming and spoofing are common threats.
DRAGN™ – PNT Resilience & Modularity
DRAGN™ is designed as a modular Resilient Position, Navigation, and Timing (R-PNT) solution to face the rise of new technical threats on the battlefield (jamming, spoofing, meaconing …). Since resilience cannot be based on a single sensor, DRAGN™ is based on a layered architecture built on:
- A highly resilient GNSS receiver featuring high signal-to-noise ratio, advanced jamming and spoofing detection, and mitigation capabilities (with an optional CRPA antenna)
- A high-accuracy, low-SWaP-C inertial measurement unit (IMU)
- An adaptive, resilient PNT algorithm that leverages multiple sensors, including cameras, magnetometers, air-data sensors, atomic-grade oscillators, and collaborative navigation techniques
- AI-powered visual map matching algorithm for an absolute position fix as often as possible while the ground is visible (even at night thanks to IR camera).
