Safran launches its most advanced Miniature Rubidium Atomic Clock, delivering unmatched stability in extreme environments.

Prague – October 27, 2025 – Safran Electronics & Defense launches MIRA, its second-generation Miniature Rubidium Atomic clock setting a new standard in precision timing technology for defense, aerospace, telecom, and industrial markets.

Building on the company’s 30 years of expertise in compact Rubidium atomic clocks – over 40,000 sold in the past decade – MIRA sets a new benchmark in performance. Smaller, lighter, and the most power-efficient in its class (0.5 W), it delivers superior accuracy and resilience. Its unique configuration allows two levels of performance and power consumption, unmatched in the market. With a holdover of less than 500 nanoseconds over 24 hours (at fixed temperature), MIRA ensures a stable signal even without GNSS. Its compact 40 cc design, with a reduced height of only 16 mm, makes it ideal for mobile systems and PCB mounting in space-constrained environments.

MIRA is engineered to withstand extreme environments, operating reliably from – 40°C to +80°C and enduring 50g shock, 7.7 gRMS vibration, and high-altitude flight – without loss of atomic lock. Its standard interfaces and flexible disciplining functions enable seamless integration, supporting rapid upgrades for both new and legacy platforms. Importantly, MIRA addresses today’s electronic warfare challenges by guaranteeing timing continuity in GNSS-denied or contested environments, where resilience and independence from vulnerable satellite signals are mission-critical.

The benefits are immediate: reliable operation in harsh environments, longer autonomy for portable systems, and faster deployment across critical infrastructure. MIRA supports a wide range of applications, including secure telecom and satcom networks, radars, navigation systems, counter-UAV systems and synchronization of UAV communications and payloads.

“By combining atomic-level accuracy with unmatched resilience and portability, we are enabling the next generation of applications – from critical networks to inertial navigation systems, and ultimately to LEO space missions,” said Jérôme Auger, Product Manager at Safran Electronics & Defense. “We also give our customers confidence that their missions will remain secure and synchronized, even when GNSS is compromised by electronic warfare methods.”

With MIRA, Safran reinforces its role as a trusted leader in Precision Navigation and Timing solutions. This next-generation technology not only enhances mission reliability for defense and aerospace, but also safeguards vital infrastructure across telecom and industry – shaping a more secure and connected future.
