HEKA Advances the Future of GPS-Denied Navigation with Nautilus DRIMU

HEKA unveils Nautilus DRIMU, delivering AI-driven GPS-denied navigation for defense, aerospace, and commercial autonomy.
As global defense and commercial operators face the growing reality of jammed, spoofed, or unavailable GPS signals, the Nautilus DRIMU addresses a critical need for resilient, autonomous navigation. Leveraging proprietary AI/ML sensor fusion, Nautilus integrates cutting-edge MEMS sensors, micro-hemispherical resonating gyroscopes, and onboard Kalman filtering to deliver unprecedented accuracy, reduced drift, and adaptive error correction.
"GPS denial is no longer a future threat - it is a present-day operational challenge," said Stephen Stilwell, Lead Flight Simulation Software Engineer & Project Manager at HEKA. "With Nautilus, we are giving warfighters, aerospace innovators, and commercial operators the ability to navigate confidently in the most contested domains."
A Foundation for Defense and Beyond
While Nautilus is built to meet the rugged demands of defense aviation, UAS swarms, and hypersonic systems, its dual-use design extends applications into commercial aerospace, autonomous vehicles, and maritime operations. By coupling AI-driven prediction with traditional dead reckoning, Nautilus provides continuous navigation assurance across air, land, and sea.
Nautilus is part of HEKA's expanding portfolio of disruptive technologies, including:
Voltai Energy Solutions - a modular, chemistry-agnostic battery management system (BMS) with >99% efficiency and multi-protocol communication for UAVs, defense platforms, and industrial energy storage.
HekaLink IDE - a 6-DOF digital twin for real-time design, testing, and validation of flight controls and guidance algorithms.
HEKOS RTOS - a safety-critical, DO-178C certifiable real-time operating system for deterministic execution in mission-critical systems.
CETUS UAS - a low-cost, modular quadcopter designed for training, reconnaissance, and commercial applications.
Together, these technologies form a complete ecosystem enabling rapid design, validation, and deployment of next-generation autonomous systems.
Market Opportunity
The global demand for GPS-alternative navigation is accelerating, with the U.S. Department of Defense and allied nations investing heavily in resilient positioning, navigation, and timing (PNT) systems. Commercial markets such as autonomous vehicles, aviation, and logistics are projected to expand this demand into multi-billion-dollar opportunities over the next decade.
HEKA's vertically integrated approach - spanning power, control, navigation, and simulation - positions the company as a trendsetter in aerospace autonomy and defense modernization.
