Safran Federal Systems announced the U.S. launch of the Blacknaute Inertial Navigation System, a next-generation solution engineered to deliver precision navigation in GPS-denied and Electronic Warfare-contested environments, at the 2025 Association of the United States Army (AUSA) Annual Meeting & Exposition. Purpose-built for the U.S. DoD community, Blacknaute™ is powered by Safran's patented HRG Dual Core technology, which is field-proven and trusted across mission-critical applications worldwide. The system is designed to support current platforms and other emerging DoD platforms requiring resilient positioning, navigation, and timing (PNT).

"Blacknaute™ represents a leap forward in GPS-denied inertial navigation," said Jon Leombrone, Executive Vice President of Navigation Systems at Safran Federal Systems. "With high-performance capabilities, modular architecture, and an open-systems design, Blacknaute™ is built to meet the evolving demands of next-generation defense platforms."

Key features of Blacknaute™ Inertial Navigation System

• Precision Inertial Performance: Achieves better than 0.4 nmi/hour drift, enabling sustained accuracy in GPS-contested or denied environments.
• HRG Dual Core Technology: Patented hemispherical resonator gyro platform with decades of proven military and space-grade performance.
• M-Code Ready GNSS Receiver: Integrated multi-constellation receiver with M-Code support for secure military satellite navigation.
• Ultra-Stable Atomic Clock: Delivers precise timing with drift of less than 1 second per 30,000 years, enhancing system integrity and synchronization.
• EW-Resilient with IDM Technology: Proprietary Interference Detection and Mitigation (IDM) supports jamming/spoofing resistance and threat awareness.
• SWaP-Optimized for Tactical Platforms: Lightweight (<16 lbs.), modular, and ruggedized for fixed-wing, rotary, and autonomous systems.
• Standards-Based Integration: MIL-STD interfaces and TSO-C220 compliance; fully aligned with open mission systems architecture.
