Safran Electronics & Defense debuts resilient PNT system

Safran Electronics & Defense has introduced BlackNaute, a new autonomous positioning, navigation and timing (PNT) system. The system integrates Safran’s HRG Dual Core inertial navigation technology, the Skylight multi-mode GNSS receiver board and an atomic clock to offer navigation resilience in challenging electronic warfare environments.

BlackNaute’s built-in atomic clock is designed to maintain precise timing, which is essential for secure communications and collaborative combat operations. The system features advanced anti-jamming and anti-spoofing algorithms, which have been validated in more than 16,000 operational cases. These capabilities allow BlackNaute to detect compromised signals and automatically switch to autonomous and trusted navigation and timing sources to ensure continuity of operations.

Its modular design allows it to be adapted across a variety of platforms. Airbus Helicopters has selected the NH90 to be equipped with this new Embedded GNSS and Time INS (EGTI).

“What we are offering today is not just a new solution — it’s an operational guarantee, designed to meet the challenges of electromagnetic warfare,” said Alexandre Ziegler, Executive Vice President, Defense Global Business Unit at Safran Electronics & Defense. “It is a concentration of innovation combining precision, versatility, and security to ensure positioning, navigation and timing — anywhere, under any circumstances.”
